Marks & Spencer: Effectiveness of worker voice apps in detecting supply chain exploitation and modern slavery risks 2025-2026

Marks and Spencer; the global clothing chain currently relies on digital worker voice applications to detect modern slavery and exploitation within its global supply chains worldwide. Between 2019 and 2025, the retailer shifted its auditing method after traditional third party social audits failed to capture hidden supply chain related modern slavery exploitations. An independent gap analysis by Oxfam showed that the retailers standard audits missed worker sentiment and concealed labor abuses.

In response, Marks and Spencer launched a pilot program in November of 2019 and started using the nGaje platform across 12 suppliers. The trial later expanded to 48 sites by late 2020. Records from the initial rollout confirmed that 97 percent of participating employees found the nGaje voice platform application easy to use. The nGaje digital survey system allows workers to report labour conditions anonymously in multiple languages and this direct reporting channel bypasses local management.

By 2021, the company expanded the program to over 500 food supplier sites in the United Kingdom. Since the beginning of this nGaje partnership, more than 30, 000 workers have submitted direct feedback. Subsequently the application keeps tracking indicators of forced labor, harassment, discrimination, and compulsory overtime.

In 2022, Marks and Spencer introduced the Everyone Business Application for its Clothing and Home division. This tool enables corporate colleagues to log observations during factory visits. The company also tracks noncompliances related to freely chosen employment through SEDEX and SMETA audits. In the 2021 to 2022 reporting period, auditors recorded five noncompliances in this category. By the 2023 to 2024 period, the number dropped to four. In the 2024 to 2025 reporting period, auditors found three noncompliances.

The retailer reviewed the three years of its worker voice program in 2024. Following this review, Marks and Spencer onboarded a new delivery partner to expand the tracked indicators. The cohort of supplier sites transitions to this updated system between June 2024 and June 2025. The mandatory program applies to all tier one sites in the United Kingdom and the Republic of Ireland. The data feeds directly into the corporate environmental, social, and governance reporting structure.

The retailer also integrates external intelligence to verify internal application data. In 2019, the company expanded its sponsorship of the Modern Slavery Helpline. Records from that year confirm that 50 percent of cases reported to the helpline involved forced labor situations. This external data provides visibility for suspected cases linked to the retailer. When the digital tools or external helplines detect a violation, the human rights manager investigates the site and mandates remediation. This dual method ensures that digital feedback results in verified corrective actions on the factory floor.

Marks and Spencer mandates worker voice applications across all tier one production sites. The retailer introduced this requirement in 2024. The mandate aligns with the Global Supply Chain Worker Voice Best Practice Guidelines. The company uses the nGaje application to collect direct feedback from employees. In specific regions, the retailer deploys alternative software. The company began working with the Timby platform in India and Pakistan during the 2024 to 2025 reporting pattern. These digital tools replace periodic audits with continuous data collection methods.

The data collection method relies on direct employee participation. During the 2022 to 2023 reporting period, the nGaje software recorded 30, 967 responses. This figure represented nearly one third of the workers at the participating sites. By the 2023 to 2024 pattern, the participation numbers increased. The company recorded 40, 807 participants across 361 sites in the United Kingdom and the Republic of Ireland. The data allows the retailer to track workplace conditions and identify modern slavery risks. The software converts worker feedback into quantifiable metrics.

The second phase of the worker voice program launched between June 2024 and June 2025. This phase introduces new indicators to detect modern slavery risks. The updated software tracks forced labor indicators, wage disputes, and workplace harassment. The data collection process requires suppliers to implement corrective action plans based on the application results. The retailer monitors these action plans through a centralized database.

Traditional audits run parallel to the digital feedback tools. The company uses Sedex Members Ethical Trade Audits to inspect supplier sites. During the 2024 to 2025 period, these audits identified three violations related to forced labor in the Fashion, Home, and Beauty supply chain. This number decreased from four violations in the previous year. The digital applications capture daily grievances that periodic physical inspections miss. The combination of physical audits and digital feedback creates a detailed view of the supply chain.

The retailer updated its grievance procedures in July 2022. The updated rules comply with the Advisory, Conciliation and Arbitration Service guidelines. The procedures dictate how the company investigates complaints submitted through the digital tools. The company requires suppliers to resolve identified problems within specific timeframes. The data shows a direct correlation between application usage and faster resolution times for workplace disputes.

The table details the participation metrics and audit findings from the 2022 to 2025 reporting pattern.

The data confirms the expansion of the digital feedback tools. The retailer uses the metrics to enforce compliance across its global supply chain. The information gathered from the applications dictates where the company deploys physical auditors. The software acts as an early warning system for labor exploitation. The retailer plans to expand the application usage to tier two suppliers in future reporting pattern.

M&S publicly discloses its tier one supply base through an Interactive Supplier Map. The company launched this mapping tool in 2016 and updates the data regularly. The map displays production countries, factory locations, and specific site profiles. The database includes metrics on worker representation and gender demographics. In 2024, the retailer signed the Transparency Pledge to further open its supply chain data to public scrutiny. The company uses the Open Supply Hub to share site information with independent researchers and labor rights organizations.

The retailer expanded its ethical compliance policy to tier two suppliers in 2024. The company initiated a supply chain mapping exercise to gain visibility into these deeper production levels. The digital feedback tools support these mapping efforts by identifying undocumented subcontractors. The company also funds specific training programs. By February 2025, the retailer trained 1, 144 tea and coffee farmers across five countries. Women made up 56 percent of these participants. The training covered leadership skills and financial literacy. The company financed these initiatives through the A Cup of Ambition fund.

The retailer shares its grievance data with external organizations to study workplace. In 2023, the company contributed to a research study examining worker and management experiences with grievance systems in the garment sector of Cambodia. The study analyzed how employees interact with digital reporting tools compared to traditional human resources departments. The findings influenced the 2024 rollout of the Global Supply Chain Worker Voice Best Practice Guidelines. The guidelines dictate that digital reporting tools must guarantee anonymity to protect workers from retaliation.

The company relies on local non governmental organizations to implement the digital tools. In India, the retailer partnered with the South India Garment and Textiles Supply Chain Programme and the Social Awareness and Voluntary Education organization. These partnerships ensure the digital applications accommodate local languages and cultural contexts. The software offers multiple language options to serve diverse migrant worker populations. The data collected from these localized deployments feeds into the central ESG reporting system. The retailer presents this data quarterly to its executive committee to shape future sourcing decisions.

Marks and Spencer deploys a fragmented targeted digital architecture to monitor factory conditions. The retailer divides its software deployment based on product categories and geographic regions. This method allows the company to bypass traditional audits and collect raw data directly from the factory floor. The technology stack relies on four primary applications. These include nGaje, Ulula, Just Good Work, and Laborlink. Each software serves a distinct demographic within the global supply chain.

The nGaje platform dominates the Food division in the United Kingdom and the Republic of Ireland. By 2021, the retailer connected digitally with almost 3, 000 workers across 54 food sites. The company trained 230 food suppliers to use the technology. Internal metrics show that 97 percent of these suppliers found the tool useful. The software measures 10 core metrics. One of these core metrics tracks worker awareness and response to modern slavery. The application functions on mobile devices and bypasses local management to secure unfiltered responses.

For the Clothing and Home division, the retailer uses Ulula. The company partnered with the ethical trade consultancy Impact to deploy this software in India. Ulula connected with almost 3, 000 workers in the region. The platform gathers anonymous feedback through text messages, voice calls, and a dedicated mobile application. This digital channel protects workers from retaliation and provides real time data on factory conditions.

Seasonal agricultural workers face different vulnerabilities. To address this demographic, Marks and Spencer financed the development of the Just Good Work application. The tool migrant laborers in the United Kingdom and southern Spain. Regions like Almeria, Murcia, and Huelva rely heavily on seasonal labor. The application educates workers about their legal rights and contractual entitlements in their native languages. The software functions as a direct countermeasure against exploitative recruitment agencies. By providing immediate access to local labor laws, the application prevents recruiters from charging illegal fees or withholding passports. The retailer reported that the tool minimizes scheme costs to recruiters and independently assesses scheme operations. By 2023, workers had downloaded the software 19, 000 times.

The retailer also used Laborlink during its Global Community Programme. The Global Community Programme targeted financial literacy among factory workers. The Laborlink surveys provided baseline data on worker banking habits. The company surveyed 15, 626 workers before and after training sessions using mobile phone technology. After the intervention, the 15, 626 surveyed workers showed marked improvement in financial independence. The data revealed that 57 percent of trained workers subsequently opened bank accounts. The direct deposit of wages into personal bank accounts reduces the risk of wage theft by factory management.

Deploying these tools across different supply chain tiers presents serious logistical challenges. Tier 1 suppliers operate under strict mandates. In 2024, the retailer required all Tier 1 production sites to implement verified worker voice systems. Tier 2 facilities operate further down the supply chain and frequently show reduced maturity in ethical compliance. During site visits, auditors found noncompliant emergency exits, excessive working hours, and incomplete payroll records at Tier 2 locations. To force compliance, the retailer expanded its audit program. In 2021, the company assessed 83 top Tier 2 fabric suppliers using the Higg Index Facility Social and Labour Module. This module evaluates recruitment practices, working hours, and wage payments. The company expanded this assessment to 250 facilities in 2022. By pushing this requirement to 250 facilities, the retailer gained direct visibility into indirect suppliers. The data collected from these assessments dictates future commercial relationships and forces suppliers to remediate identified violations. In 2024, the retailer rolled out a mandatory Tier 2 ethical compliance policy internally.

The data confirms a deliberate strategy to digitize supply chain oversight. The retailer uses distinct software platforms to match the technological literacy and specific vulnerabilities of different worker demographics. The expansion into Tier 2 facilities marks a necessary escalation in detecting modern slavery risks deep within the manufacturing base.

Marks and Spencer concentrates its food supply chain heavily in the United Kingdom. Over 80 percent of its 495 food factories operate within the UK. The company mandated the nGaje application across this domestic base. By 2022, the digital rollout reached over 500 food sites in the region. This domestic concentration allows for standardized compliance tracking. The United Kingdom and the Republic of Ireland maintain the highest consistent usage rates for the nGaje platform. Factory managers in these regions face strict reporting requirements. The company acquired Gist in September 2022 to control its food logistics directly. This acquisition brought more workers under the direct digital monitoring umbrella.

Operations in Asia present a different statistical reality. The clothing and home division sources products from 884 factories across 41 countries. The company relies on independent applications and local partnerships to gather feedback in these regions. In Thailand, Marks and Spencer partners with the Issara Institute. Workers use the Issara application to report conditions. In 2022, this system processed 105, 365 calls and messages from workers and job seekers. This massive volume of data led to the direct remediation of 34, 608 specific labor complaints. The Thai implementation proves that high engagement occurs when workers trust the reporting software.

To cover the vast Asian network, the company expanded its digital feedback programs in 2023. The new deployment reached 138 factories across seven countries. These nations include Bangladesh, Cambodia, China, India, Pakistan, Turkey, and Vietnam. The company tests various digital solutions to match local language and technology access. Adoption rates in these countries trail the United Kingdom due to fragmented factory ownership and varying internet access. In 2021, the retailer increased the scope of its audit program to 83 top fabric suppliers using the Higg Index Facility Social and Labor Module. By 2022, the company extended this digital tracking to 250 facilities.

The geographic divide shows a clear pattern in digital adoption. European suppliers use standardized corporate applications with high compliance rates. Asian suppliers generate higher total volumes of grievance reports through localized third party applications. The company operates 1, 487 stores and over 100 websites globally. Managing the 65, 000 direct employees requires different tools than managing the extended supply chain. Direct employees use the One Trust program to report grievances. Supply chain workers rely on nGaje or local alternatives.

Audit data from 2024 and 2025 shows the direct results of these digital tracking systems. Across the fashion and beauty supply chain, auditors identified 3 noncompliances under the category of freely chosen employment. This number dropped from 4 noncompliances recorded between 2023 and 2024. The food supply chain demonstrated a steeper decline in violations. During 2024 and 2025, auditors found 6 noncompliances relating to freely chosen employment in the food sector. This represents a sharp drop from the 18 violations discovered in the previous reporting period. The company attributes this reduction to the continuous monitoring provided by worker voice applications. Traditional audits only capture a single moment in time. Digital applications provide constant surveillance of factory conditions. During the early pandemic period, the company managed to conduct 48 physical audits across Europe and Asia. The digital tools filled the surveillance gap when physical inspections became impossible.

The company also shares its geographic data with external partners. Marks and Spencer operates as a founding member of the Modern Slavery Intelligence Network. This group formed in response to Operation Fort, the largest modern slavery investigation in the United Kingdom. Members pool intelligence gathered from their respective supply chains. The nGaje application feeds localized data into this broader national network. This data sharing helps identify regional patterns of exploitation before they spread across multiple suppliers. The integration of factory level data with national intelligence networks represents a major shift in supply chain management.

The data reveals that a single application cannot serve the entire global supply chain. The United Kingdom food sector achieves high adoption through strict corporate mandates. The Asian clothing sector requires localized tools to overcome language differences and fragmented ownership. The retailer continues to adjust its digital strategy based on these geographic realities.

Digital reporting tools face a central challenge. Workers fear retaliation from factory management. Marks and Spencer acknowledged this reality in their 2021 and 2022 Modern Slavery Statements. Corporate directors noted the difficulty of collecting data that protects worker anonymity while allowing the company to respond and guarantee remedy without revealing the identity of the reporter. If a factory supervisor can identify a complainant, the reporting software becomes a liability rather than a shield. The company stated that their priority was to develop a process to respond appropriately to feedback while maintaining strict confidentiality. The retailer recognized that multiple brands setting up overlapping worker voice programs could cause confusion. Protecting the identity of at risk workers remains the top priority for any digital compliance program.

An investigation by Oxfam in 2021 into the food and footwear supply chains of the retailer revealed severe retaliation fears. Researchers interviewed nearly 400 workers across the United Kingdom and India. The findings made uncomfortable reading for companies relying on a large low paid workforce. Workers detailed concerns including in work poverty, long term damage to health, poor sick pay, and poor worker representation. In India, researchers documented extremely low wages and debt. Women faced huge obstacles to career progression. Workers at three sites reported that only company managed trade unions were permitted. Trade unionists stated they worked anonymously to avoid retaliation from their employers. Production pressure, hostility to trade unions, and the prevalence of precarious jobs were all named as obstacles to fair negotiation. This reality forces digital platforms to guarantee absolute data security.

To address these security gaps, the retailer shifted its methods. By 2021, the company integrated nGaje, an anonymous and multilingual reporting platform, across its major production hubs. The software encrypts user identities, preventing local managers from intercepting complaints. The retailer offers the opportunity for workers to input their comments directly into the system. Since its launch, the company has heard from over 30, 000 workers. Closer engagement provides direct insight into working conditions and worker sentiment. The company provides supplier partners with their in total score for each area of focus and uses the survey results to identify problems. The retailer established a new board committee to review the material and provide a steer to the business. This executive oversight guarantees that anonymous reports receive immediate attention from top leadership rather than being buried by middle management.

Industry data from Ulula between 2022 and 2023 recorded nearly 1, 500 grievances across supply chains. The firm anonymized and aggregated the results of incoming worker grievances over four quarters. Payment reimbursement, wage disputes, and labor rights dominated the reports. Discrimination and facility complaints remained consistently low. In the apparel sector specifically, labor rights were the primary concern for workers, alongside unethical behavior. This data proves that when anonymity is secure, workers prioritize financial and legal violations. The inclusion of worker voice with real time, two way communication on human rights due diligence matters represents a major shift for supply chain management. Businesses need primary data to guide them towards the most meaningful and direct actions.

The Responsible Business Alliance launched RBA Voices to provide secure escalation options for workers. The system manages all cases within a protected database designed to safeguard submitter identity. Marks and Spencer enforces a strict anti retaliation policy. The retailer requires supplier partners to provide secure grievance tools for workers and communities. The company promotes workplace representation by participating in initiatives which provide capacity building to factories on freedom of association, such as the International Labour Organization Better Work programme. The retailer publicly disclosed its tier one supply base to increase transparency about where its products are made. The public map highlights production countries, individual factory locations, and profiles for sites used by direct suppliers. This level of transparency, combined with secure digital reporting, creates a safer environment for workers to speak out against exploitation.

When a worker submits a grievance through a digital voice application, the data triggers a strict escalation procedure. Marks and Spencer routes all digital flags concerning forced labor or human trafficking directly to specialist Sourcing Office compliance teams. These teams operate in high risk sourcing regions including Bangladesh, Cambodia, China, Hong Kong, India, Pakistan, Sri Lanka, Turkey, and Vietnam. Local presence allows investigators to bypass factory management and verify digital claims directly with the affected workforce.

The retailer relies on the Whistleblowing Standard Operating Procedure to govern the initial response. For agricultural and grocery suppliers, the company applies the United Kingdom Food Supply Chain Serious Incident Escalation and Management procedure. This framework standardizes the investigation process across the industry. Investigators cross reference digital alerts with data from the Unseen Helpline Business Portal. This external partnership provides an additional level of verification for suspected labor exploitation.

Verified data from the 2024 to 2025 reporting period reveals the exact volume of these escalations. Marks and Spencer received 11 allegations with a possible link to labor exploitation through its reporting channels. Following investigations in the food supply chain, the company confirmed 6 non compliances related to the principle that employment is freely chosen. These violations included 3 instances of illegal recruitment fees and 2 cases involving incorrect notice periods. The fashion, home, and beauty division recorded 3 similar non compliances during the same period.

The escalation process demands immediate remediation. Suppliers must eliminate illegal recruitment fees and reimburse affected workers. The company monitors these corrective actions through follow up audits and continuous digital polling. If a supplier fails to correct the violation, Marks and Spencer initiates a formal disengagement process. The corporate policy dictates that disengagement must follow strict rules to prevent abrupt factory closures that could leave at risk workers destitute.

To visualize the distribution of confirmed labor violations across divisions, the following chart details the non compliances recorded in the 2024 to 2025 period.

The Board Environmental Social and Governance Committee reviews the escalation data quarterly. This executive oversight guarantees that regional compliance teams possess the necessary authority to enforce remediation. The integration of digital worker voice applications with the Safecall independent hotline creates a direct line from the factory floor to the corporate boardroom. This structure removes middle management filters that previously concealed exploitation. By digitizing the initial complaint, the retailer forces a documented, auditable response to every modern slavery allegation.

Automated worker voice applications generate thousands of data points across global supply chains. Retailers rely on these digital platforms to detect modern slavery and forced labor. The accuracy of these systems remains a subject of intense scrutiny. Supply chain auditors face two distinct statistical errors. False positives occur when an application flags a compliant supplier for labor violations. False negatives occur when the software fails to detect active exploitation. Balancing these two extremes determines the actual effectiveness of digital monitoring tools.

Marks and Spencer relies on the nGaje platform and other audit methods to monitor its food and apparel suppliers. During the 2024 to 2025 financial year, audits of in scope suppliers within the food supply chain identified six non compliances relating to the principle that employment must be freely chosen. This figure represents a decrease from the 18 non compliances recorded during the 2023 to 2024 reporting period. The reduction in flagged violations raises a central question. Are suppliers improving their labor practices, or are workers learning to bypass the reporting software?

Hidden exploitation represents a serious threat to supply chain integrity. A 2019 British Academy study by researchers Lisa Rende Taylor and Elena Shih evaluated worker feedback technologies across seven countries. The researchers found that due diligence oriented technology tools rarely identified modern slavery. Workers showed little trust in business driven applications and feared retaliation from their employers. Conversely, the study noted that worker focused feedback tools managed by independent organizations regularly identified forced labor and human trafficking. When workers do not trust the platform, they submit neutral or positive feedback. This creates a false negative, masking active abuse.

False positives create a different set of operational challenges. The New South Wales Government published a 2023 guidance document on reasonable steps for supply chain monitoring. The report noted that commercial risk tools frequently create false positives. digital systems analyze modern slavery risks at the country and product level rather than penetrating specific worksites. This broad analytical method flags a large number of high risk suppliers. Companies then expend significant resources investigating alerts that yield no actual evidence of exploitation. When compliance teams waste time on false alarms, actual victims of forced labor remain hidden.

Anonymity drives data accuracy. EcoVadis released 2025 data from its Worker Voice survey tool, which collected over 90, 000 survey data points across 89 countries. The platform supports 144 languages. The findings show that more than 80 percent of workers in key countries reported satisfaction with grievance channels when the system guaranteed their anonymity. Removing the fear of reprisal encourages workers to provide candid insights about excessive overtime and unsafe environments.

Collecting vast amounts of worker data introduces severe security risks. In May 2025, Marks and Spencer suffered a massive cyber attack that compromised personal data. When retailers gather detailed feedback from thousands of factory workers, they create a centralized database of highly sensitive information. If hackers breach these systems, the exposed data places whistleblowers in direct danger. A compromised identity transforms a digital weakness into a physical threat for the reporting employee.

Marks and Spencer continues to adjust its digital monitoring strategy. In 2025, the retailer launched the second phase of its worker voice programme. The company built this updated version to identify a broader range of possible modern slavery indicators. By refining the questions asked through the application, the retailer aims to reduce false positives while capturing subtle signs of coercion.

The effectiveness of automated alerts depends entirely on the quality of the data entered by the workforce. If a digital tool asks the wrong questions, it generates inaccurate risk profiles. Retailers must verify digital alerts through physical inspections and independent worker interviews. Software applications can process thousands of surveys in seconds, they cannot replace the verified findings of a trained human rights investigator.

Migrant laborers face severe language and literacy obstacles when navigating foreign agricultural and manufacturing sectors. Conventional auditing methods break down when workers cannot read their employment contracts or understand their legal rights. To bypass these communication blocks, Marks and Spencer funds and deploys targeted digital applications designed specifically for non native speakers and workers with low reading proficiency.

The retailer relies heavily on the Just Good Work application to reach seasonal laborers. By October 2024, over 52, 000 job seekers and successful visa scheme applicants had accessed the software. The platform delivers essential information regarding recruitment, visas, and workplace rights directly to the user. To accommodate diverse labor pools, the application supports multiple languages including Romanian, Bulgarian, Polish, Ukrainian, Kiswahili, Nepali, and Bahasa Indonesia. Data from the Gangmasters and Labour Abuse Authority in 2023 indicates that Russian is the most frequently used language on the platform among seasonal agricultural workers arriving from Central Asia. The application also features inline questions and checklists that users can submit anonymously. This continuous feedback loop gives the retailer visibility into the recruitment journey before the worker even arrives in the destination country.

Text based translations alone do not solve the accessibility problem for workers who cannot read. The Just Good Work platform integrates audio and visual capabilities to bypass written text entirely. Workers can watch animated videos or listen to audio recordings explaining their rights in their native dialects. The software also functions entirely offline. Users can download the necessary files while connected to Wi Fi and access the materials later in remote agricultural fields where cellular data is unavailable. The offline mode includes a secure storage feature where workers can save digital copies of their passports, visas, and employment contracts.

Marks and Spencer also uses the nGaje platform to conduct anonymous worker sentiment surveys across its supply chain. The retailer rolled out this digital program to more than 500 sites in the United Kingdom. The nGaje system presents 13 specific statements to employees and asks them to agree or disagree. To ensure comprehension, the software converts these surveys into the native languages of the workforce. During its year of operation, the program generated 29, 338 worker responses, which included over 4, 000 free text comments. The digital survey format allows the retailer to aggregate results quickly and identify sites requiring immediate intervention. By removing the language barrier, the system captures a more accurate picture of factory floor conditions than conventional audits. In 2019, Marks and Spencer partnered with the Co op supermarket chain and nGaje to publish an Communication Toolkit. This resource provides suppliers with exact steps to manage multi language workforces and ensure digital grievance channels remain accessible to all employees.

In Southeast Asia, the retailer partners with the Issara Institute to monitor labor conditions in Thailand. The Issara Institute operates a multi lingual hotline, social media chat channels, and a local language smartphone application. Over 3, 000 of the 100, 000 workers linked into the Issara Institute network belong directly to Marks and Spencer supply chains. Since 2014, the organization has resolved over 25, 000 cases of labor exploitation. Of those resolved cases, over 6, 000 involved individuals in forced labor situations. The technical support and direct worker feedback overhauled exploitative labor brokering systems into compliant human resource operations. During 2022 alone, the Issara Institute handled 105, 365 calls and messages from workers and job seekers. By offering multiple formats for reporting, from voice calls to digital text, the system ensures that literacy levels do not prevent workers from exposing exploitation.

The expansion of these tools continues across Europe. In 2023, Marks and Spencer began financing the development of a Spanish version of the Just Good Work application. Slated for a June 2024 launch, the tool focuses on agricultural workers in Almeria, Murcia, and Huelva. The software provides a free and accessible method for laborers to understand their entitlements under Spanish agricultural regulations.

Marks and Spencer expanded the nGaje worker voice application to more than 500 food production sites in the United Kingdom by 2022. This expansion followed an initial pilot program that tested the software across 48 facilities. The software allows employees to bypass local factory supervisors and send reports directly to the retailer. Direct reporting channels bypass traditional management structures. Factory supervisors face immediate scrutiny when employees report workplace conditions directly to buyers. This direct line of communication creates friction on the factory floor. Local managers lose their ability to filter information before it reaches the corporate compliance department. The sudden transparency exposes operational flaws that supervisors previously concealed to maintain their vendor ratings.

A 2021 Oxfam investigation into the retailer supply chain exposed serious problems regarding management interference. Researchers interviewed 390 workers across British food manufacturing sites and Indian footwear factories. The investigation found that trade unionists in India worked anonymously to avoid retaliation from factory supervisors. At three specific Indian footwear sites, employees were restricted to joining labor groups managed directly by the human resources department of the company. These groups controlled by the company prevent independent union negotiations. Workers reported that supervisors actively discouraged them from raising complaints about wages or working hours. The fear of termination kept employees silent during official factory audits.

Management resistance takes three primary forms across global supply chains. Anti Slavery International documented instances in Indian garment factories where supervisors leaked information about unannounced audits to hide compliance violations. Researchers investigating these facilities faced physical threats in Delhi when they attempted to interview employees outside the factory gates. In similar industry cases in Indonesia, employees initially refused to use digital communication tools. Workers feared retaliation because previous anonymous grievance systems resulted in managers identifying and interrogating the reporting individuals. Factory supervisors frequently attempt to identify whistleblowers to suppress negative data. Supervisors confiscate mobile phones during shifts to prevent employees from accessing reporting applications.

The retailer implemented a revised Human Rights Standard in 2021 to counter this resistance. The new standard requires suppliers to conduct annual due diligence. During the 2024 to 2025 reporting period, the company reviewed the due diligence plans of 48 nominated suppliers. Compliance data from the Fashion, Home and Beauty sector recorded three compliance failures under the category of freely chosen employment in 2025. This number decreased from four recorded violations in 2024. The company uses an independent hotline called Safecall to provide an alternative reporting method for employees facing local retaliation. This secondary channel operates in multiple languages and guarantees caller anonymity.

Direct reporting applications present structural limitations. Oxfam warned that these tools give a voice to individual workers fail to establish dialogue with the direct employers. Employees remain unclear on how their specific problems find resolution when local managers are excluded from the initial conversation. The retailer mandates a strict policy against retaliation to protect workers. Suppliers must provide grievance reporting channels that do not result in disciplinary measures. Even with these policies, the power between factory supervisors and floor workers remains a serious obstacle to accurate data collection. Workers require strong union representation on the factory floor to ensure that digital reporting produces actual improvements in their daily working conditions.

Traditional supply chain inspections frequently fail to detect modern slavery. Factory managers prepare for scheduled visits, coach employees on approved answers, and falsify timesheets. This creates an audit illusion, where official reports show compliance while actual conditions decline.

In January 2021, Oxfam published an independent evaluation of Marks and Spencer food suppliers. Researchers interviewed nearly 400 workers across the United Kingdom and India. The findings exposed a severe disconnect between official audit records and daily reality. Employees reported in work poverty, insufficient sick pay, and intense production pressure. Oxfam concluded that without trusted reporting channels, serious violations remain hidden regardless of inspection frequency. Workers expressed a distinct absence of trust in standard grievance procedures, meaning they kept silent during official factory walkthroughs.

The data supports this conclusion. Between April 2019 and April 2020, traditional ethical audits across the retailer’s global supply chain identified exactly 46 noncompliances under the category of freely chosen employment. By the 2023 to 2024 reporting period, that count dropped to four. In the 2024 to 2025 pattern, inspectors found only three noncompliances related to forced labor and compulsory overtime across the entire fashion, home, and beauty division.

These low detection rates contrast sharply with data from direct worker reporting. When the company integrated the Unseen modern slavery helpline and the nGaje worker voice application, the volume of verified intelligence increased. In 2019, 50 percent of cases reported to the Unseen helpline involved situations of forced labor. The nGaje platform asks employees to agree or disagree with 13 specific statements about their workplace. This digital method bypasses factory management entirely, allowing workers to submit feedback securely from their personal devices.

Recognizing the limitations of physical inspections, Marks and Spencer changed its compliance framework. The retailer mandates annual participation in the nGaje worker voice program for all tier one supplier sites in the United Kingdom and Republic of Ireland employing 30 or more people. For high risk international suppliers, the company still requires third party ethical audits every two years, these physical checks serve as a baseline rather than the sole metric of compliance.

The shift from periodic physical checks to continuous digital monitoring represents a structural change in how the retailer gathers supply chain data. Traditional audits rely on a snapshot method, capturing factory conditions on a specific day. In contrast, the nGaje system provides ongoing sentiment analysis, allowing compliance officers to track changes in worker satisfaction over time. This continuous data stream helps identify early warning signs of exploitation before they escalate into severe abuses.

The retailer expanded its digital reporting capabilities further in the 2024 to 2025 reporting pattern. Marks and Spencer onboarded a new delivery partner to manage the phase of the worker voice program across its food supply chain. The compliance team worked with this partner to increase the count of specific indicators tracked within the application. These new metrics specifically track early warning signs of modern slavery. A cohort of supplier sites began rolling out this updated program between June 2024 and June 2025, with a second group scheduled for the following year.

The company also integrated data from the Issara Partner Supplier Dashboard for its international operations. This system provides visibility into recruitment practices and working conditions reported directly by employees through independent channels. The dashboard verifies the responses of recruiters and suppliers, offering an objective assessment of how quickly and factory managers resolve worker complaints.

By combining the nGaje application in the United Kingdom with the Issara platform internationally, the retailer built a continuous data collection network. This network exposes the audit illusion by proving that low counts of official noncompliances do not equal an absence of exploitation. Instead, the data shows that workers report abuses when provided with secure, anonymous, and accessible digital tools.

Marks and Spencer tracks the lifecycle of supply chain complaints from the moment a worker submits a digital report to the final implementation of a corrective action plan. In 2024, the retailer introduced a mandatory requirement for all Tier 1 production sites to maintain active worker voice systems. This directive forces suppliers to integrate digital reporting tools directly into their daily operations. The resulting data feeds into the retailer’s environmental, social, and governance reporting framework. Executives monitor these metrics quarterly through the ESG Committee to measure the speed and success of supplier responses.

The company applies a strict methodology to process incoming data from platforms like the Issara Partner Supplier Dashboard and the Unseen Helpline Business Portal. The Issara dashboard gives the retailer direct visibility into recruitment and working conditions based on ongoing worker feedback. Independent organizations verify the responses from suppliers and recruiters, providing an objective assessment of both the quality and the timeliness of the remediation efforts. When a worker submits a grievance through the Safecall web reporting facility or a mobile application, the system triggers an exact timeline. Administrators must acknowledge receipt of the digital complaint within two working days for English submissions. Submissions in other languages receive an acknowledgment within five working days. This initial contact establishes a direct line of communication between the reporting worker and the compliance team.

Following the initial acknowledgment, investigators assess the complaint to determine the severity of the alleged exploitation. The official grievance procedure dictates that the company investigates all legitimate reports and promotes a resolution in the quickest possible timeframe. Yet, the exact duration of the remediation phase varies heavily based on the nature of the violation. The retailer explicitly states that while minor compliance matters reach a resolution in a matter of weeks, serious exploitation cases can take months or years to fully remediate. The protection of the reporting worker remains the primary concern during this period. Marks and Spencer enforces a strict anti-retaliation policy, ensuring that any supplier found punishing a worker for using a digital voice application faces immediate disciplinary action.

During the 2024 to 2025 reporting period, Marks and Spencer recorded 11 specific allegations linked to suspected labour exploitation or modern slavery. These reports surfaced through the Modern Slavery Helpline and various digital reporting channels. The compliance team investigates all allegations and mandates risk mitigation measures at either the factory level or the broader industry level. When investigators confirm a violation, they require the supplier to draft a corrective action plan. This document must include a specific time period for completion and an assigned monitoring strategy. In instances, the retailer deploys a third-party auditor to monitor the implementation of these corrective actions.

The resolution phase officially begins when all parties agree on the remedial action plan. The compliance team tracks the closure of non-compliances through follow-up audits and continuous worker feedback. Historical data shows the value of these tracking methods. During the 2016 to 2017 period, ethical audits identified 12 non-compliances related to forced labour indicators, including recruitment fees, mandatory overtime, and restricted toilet breaks. By transitioning to digital worker voice tools, the retailer captures these violations in real time rather than waiting for an annual audit. If a supplier fails to implement the required changes within the agreed timeframe, the retailer escalates the matter. In cases where no agreement materializes after a thorough investigation, Marks and Spencer reserves the right to take unilateral action regarding the supplier contract. The integration of digital worker voice tools ensures that the retailer retains a permanent, timestamped record of every interaction, preventing suppliers from ignoring or delaying the remediation process.

Marks and Spencer allocates significant capital to digital compliance and worker voice applications. The financial data from the 2024 to 2025 reporting period shows a direct correlation between supply chain transparency and corporate profitability. The retailer reported 13. 9 billion pounds in group revenue. The food division generated 9. 0 billion pounds. The fashion home and beauty division generated 4. 2 billion pounds. Group profit before tax reached 511. 8 million pounds. The company maintains an annual capital investment envelope between 500 million and 600 million pounds. A portion of this capital funds the nGaje worker voice platform.

The software expanded to 500 food sites across the United Kingdom by 2022. The digital expansion replaced manual audit processes. Manual audits require physical inspectors and generate high travel expenses. Digital compliance tools reduce these recurring expenses. The corporate strategy aims for over 500 million pounds in structural cost reductions. The cost benefit analysis reveals that digital worker voice tools prevent supply chain disruptions. The nGaje application allows workers to report grievances anonymously. This early detection system mitigates the risk of modern slavery. Modern slavery incidents result in severe legal penalties and brand damage. The financial protection offered by digital compliance far outweighs the software licensing fees.

The retailer commissioned Oxfam to conduct independent research into its supply chain. The investigation required funding for researchers to interview 390 workers across United Kingdom food manufacturing sites and Indian footwear factories. The six month study identified areas requiring financial intervention. Workers reported the inability to meet living costs. The findings prompted the retailer to expand the nGaje application. The software deployment requires initial setup fees and ongoing maintenance costs. The investment provides real time data on worker sentiment. The application asks employees to agree or disagree with 13 statements. The system processes responses in multiple languages. The translation features eliminate the need for costly human interpreters during standard compliance checks.

Financial stability allows the company to fund these ethical initiatives. The Marks and Spencer Employee Benefit Trust holds over 40 million shares. These shares carry a market value of 143. 9 million pounds. The company operates a joint venture with Ocado. The retailer holds a 50 percent investment in the grocery delivery business. The diversified revenue streams protect the core business from market volatility. The financial health of the organization enables long term investments in supply chain visibility. The business recorded an operating profit before adjusting items of 890. 1 million pounds. The strong balance sheet supports the mandatory rollout of the worker voice program.

Suppliers in the United Kingdom and the Republic of Ireland must participate in the digital compliance program. The mandate shifts operational costs to the supplier network. Suppliers must allocate time for workers to complete the digital surveys. The retailer provides capacity building tools to offset these operational expenses. The company launched three toolkits for suppliers focusing on ethical trade and lean manufacturing. Lean manufacturing principles help suppliers recover the time spent on compliance activities. The financial return on investment manifests in reduced labor turnover and higher product quality. The retailer sells more own label Fairtrade tea and coffee than any other United Kingdom competitor. The ethical sourcing strategy motivates consumer purchases and supports the 9. 1 percent increase in food sales reported in 2025.

The retailer also invests heavily in its direct workforce. Marks and Spencer made a record investment of 95 million pounds in store colleague pay. The company raised over 1. 7 million pounds of Fairtrade Premium for farmers and workers in 2021. The business holds net funds exceeding 400 million pounds. The operating profit margin for the fashion home and beauty division reached 11. 2 percent in 2025. The food division achieved a 5. 2 percent adjusted operating profit margin.

Marks and Spencer expanded its digital grievance infrastructure across the Indian cotton and garment sector during the 2024 to 2025 financial year. The retailer integrated the Timby application into its supply chain through the South India Garment and Textiles Supply Chain Programme. The company partnered with the local nonprofit organization SAVE to deploy this software across tier one factories. This deployment followed extensive pilot programs in the Clothing and Home division. Those initial trials reached over 70, 000 workers across more than 90 factories. The data collected from these pilots prompted the company to mandate worker voice software for all tier one production sites in 2024.

The shift toward mobile reporting tools originated from a 2018 gap analysis conducted by Oxfam. Researchers interviewed 390 workers across the food and footwear supply chains. Women constituted 49 percent of the respondents. The resulting report showed that traditional annual audits failed to capture the daily realities of factory workers. Workers reported hesitance to use factory managed complaint boxes due to fear of retaliation. The digital application bypasses local management. Workers submit complaints directly through their mobile devices. The system routes these reports to specific compliance officers and NGO partners for verification.

The Timby application categorizes complaints into specific operational areas. These categories include wage disputes, excessive working hours, harassment, and health violations. The South India Garment and Textiles Supply Chain Programme focuses heavily on the Tamil Nadu region. This area contains a high concentration of spinning mills and garment factories. The program operates resource centers to train workers on using the application. Training sessions educate employees on their labor rights and the anonymous reporting process. The software supports multiple local languages to ensure accessibility for migrant workers.

The implementation of this technology provides quantitative data on factory conditions. The continuous stream of worker feedback replaces the static snapshot of an annual audit. Compliance teams track the resolution time for each submitted complaint. The company requires suppliers to demonstrate active remediation of verified reports. Failure to address worker feedback results in corrective action plans. The retailer maintains a strict policy against retaliation for any worker who submits a report. The digital platform logs all interactions to create an auditable trail of the grievance process.

Marks and Spencer relies on digital reporting tools to bypass factory management and gather direct feedback from garment workers in Bangladesh. The retailer expanded its worker voice program to 138 factories across seven countries by 2023. In Bangladesh, the company uses applications like nGaje and Laborlink to detect labor violations that traditional audits miss. These platforms allow employees to submit anonymous reports outside of working hours. The anonymity builds trust among workers who fear retaliation for speaking out against supervisors.

The numbers show high engagement when workers feel safe from reprisal. Across the global supply chain, the nGaje platform recorded 30, 967 responses during its initial rollout. This figure represents nearly one third of the total workforce at the participating sites. Marks and Spencer mandated these digital feedback systems for all tier one production sites in 2024. The mandate forces suppliers to maintain active channels for employee grievances.

In Bangladesh, the absence of independent trade unions makes third party applications a primary method for reporting abuse. Factory owners frequently control internal worker committees. This control suppresses legitimate complaints about forced overtime and wage theft. Digital applications remove the middleman. Workers use their personal mobile phones to answer surveys about their working conditions. The software aggregates the data and sends it directly to compliance officers in London and regional managers in Dhaka.

Marks and Spencer integrates these digital tools with broader safety agreements. The retailer signed the Bangladesh Accord on Fire and Building Safety in 2013 and renewed its commitment through the International Accord in 2021 and 2023. The Accord trained 1. 8 million Bangladeshi workers on workplace safety principles. Educated workers are more likely to use digital applications to report structural dangers or locked fire exits.

During the 2020 pandemic, Marks and Spencer partnered with the CARE organization through the Supply Chains Facility fund. The project addressed the health impacts of the virus on 80, 000 garment workers in Bangladesh. The company used digital surveys to monitor factory conditions and verify that suppliers implemented proper health measures. The data collected from these applications informed the retailer about illegal wage deductions and unsafe working environments. The CARE partnership distributed emergency funds directly to workers using mobile money transfers. This direct financial link proved the utility of digital platforms to the workforce. Workers who received their wages and emergency funds through mobile applications became more to use the same devices for reporting workplace violations.

Traditional audits like the Sedex Members Ethical Trade Audit remain a standard requirement for all suppliers. Yet these scheduled inspections fail to capture the daily reality on the factory floor. Factory managers coach workers on what to say to auditors. Third party applications provide continuous monitoring. The software asks workers specific questions about their pay slips, their hours, and their treatment by supervisors.

Financial inclusion programs also use these digital platforms. Marks and Spencer participates in the Business for Social Responsibility HERfinance program. The initiative uses mobile technology to train workers on financial literacy and tracks their progress through digital surveys. The HERfinance program taught workers how to read their digital pay slips and identify unauthorized deductions. Before the introduction of these applications, factory managers routinely shortchanged workers by manipulating paper records. Digital literacy training gave workers the exact vocabulary needed to report wage theft through the nGaje system. Workers build confidence in the technology when they see it used for beneficial training rather than just compliance monitoring.

The success of these applications depends entirely on supplier cooperation and brand enforcement. Marks and Spencer requires suppliers to pay for follow up audits if the digital data reveals serious labor violations. The retailer maintains regional compliance teams in Dhaka to investigate the alerts generated by the software. When workers see their digital complaints lead to actual factory improvements, their trust in the system grows.

The European Union approved the Corporate Sustainability Due Diligence Directive in early 2024. This legislation shifts supply chain oversight from voluntary corporate social responsibility to mandatory legal compliance. The directive requires large companies to identify, prevent, mitigate, and remediate human rights violations across their entire value chain. Regulators demand that corporations establish accessible grievance channels for workers. Marks and Spencer uses digital worker voice applications to satisfy these exact legal requirements. The retailer deploys software platforms to gather direct feedback from factory floors. This digital method replaces outdated annual audits with continuous monitoring. European authorities designed the directive to eliminate forced labor and unsafe working conditions. Companies can no longer claim ignorance about the factories producing their goods. The law mandates active investigation into every tier of the manufacturing process.

Marks and Spencer relies on the nGaje platform to track worker sentiment. The company rolled out this software across its United Kingdom food supplier base. Workers respond to thirteen specific statements about their employment conditions. The application guarantees anonymity and operates in multiple languages. This setup directly answers the European Union mandate for confidential reporting channels. Traditional audits capture a single moment in time. Digital applications collect data throughout the year. Regulators expect companies to prove their due diligence processes actually work. The continuous data stream from nGaje provides the necessary evidence for compliance reporting. The retailer expands these digital implementations to cover international clothing suppliers. This expansion ensures that the company gathers standardized data across different product categories and geographic regions.

The new directive imposes strict penalties for noncompliance. Companies face fines up to five percent of their global revenue. Regulators can also ban noncompliant goods from the European market. Marks and Spencer mitigates this financial risk through its digital infrastructure. The 2024 annual report from the retailer highlights the active monitoring of compliance and responsibility metrics. Executives use the worker voice data to spot labor violations before they trigger regulatory action. The software aggregates responses and flags factories with high complaint volumes. This early warning system allows the company to intervene and correct labor violations promptly. Financial analysts view these digital compliance tools as essential risk management assets. The ability to detect and resolve labor disputes internally prevents costly public scandals and regulatory investigations.

The transition to mandatory due diligence forces retailers to abandon passive supply chain management. The European Union requires companies to engage the individuals affected by their operations. Marks and Spencer achieves this by putting the reporting tool directly into the hands of the workers. The digital platform bypasses local factory management. Workers submit their grievances directly to the buyer. This direct line of communication removes the filter that local managers previously applied to audit results. The data collected through these applications forms the backbone of the retailer legal defense under the new directive. Regulators evaluate the legitimacy and accessibility of these reporting channels. The high participation rates in the Marks and Spencer digital programs demonstrate that workers trust the system. This documented trust serves as proof that the company meets the European Union engagement standards.

Corporate boards carry the legal responsibility for supply chain violations. The European Union directive holds directors accountable for the actions of their suppliers. Marks and Spencer executives review the aggregated worker voice data to guide their sourcing decisions. The company maintains a public supplier map that details factory locations and workforce demographics. The integration of worker voice data with this mapping technology creates a clear picture of supply chain conditions. This level of transparency meets the reporting standards set by European regulators. The digital tools convert a complex legal requirement into a measurable operational metric. The retailer uses this verifiable data to prove its commitment to ethical sourcing. European authorities accept these digital records as valid evidence of active supply chain management.

Digital reporting tools collect highly sensitive information from supply chain laborers. If local factory supervisors or state intelligence agencies intercept this data, the reporting employees face immediate retaliation. Marks and Spencer deployed the nGaje software to bypass local networks and transmit worker feedback directly to senior management and retail buyers. By 2023, the retailer recorded 30, 967 individual survey responses through this secure channel.

The system architecture relies on strict data protection rules. The software de-identifies all worker-level data at the source. Administrators apply metadata scrubbing to block indirect re-identification of any single participant. The platform uses differential privacy techniques to guarantee that no statistical analysis points back to a specific person or specific workstation.

Device security forms the second line of defense. Employees complete the digital surveys on their personal smartphones. When personal devices are unavailable, the factory provides secure laptops placed in confidential locations. This physical separation prevents floor managers from looking over shoulders or tracking screen time. The interface operates in multiple languages, allowing laborers to submit feedback without relying on third-party translators who might leak information.

The Issara Institute established the baseline ethics for these digital deployments, mandating a strict “do no harm” rule for data collection. Marks and Spencer applies this rule by stripping all identifying markers from open-text comments before routing the feedback to compliance teams. Local factory management receives only aggregated scores for specific focus areas, never the raw input.

Traditional social audits force laborers to speak with external inspectors inside the factory walls. This physical proximity allows local supervisors to monitor who speaks to the auditors and for how long. The digital application removes this physical risk entirely. Workers can access the survey links outside of working hours, leaving no permanent application footprint on their devices. The system also does not log precise GPS coordinates tied to individual submissions, protecting the physical location of the user. Independent third-party organizations review the data access controls to verify these privacy claims.

Marks and Spencer merges direct employee feedback with the Supplier Ethical Data Exchange platform. The retailer requires all tier one suppliers to register on the Sedex system and complete a Self Assessment Questionnaire. Suppliers must publish a valid Sedex Members Ethical Trade Audit for each site. The company combines this audit data with worker voice metrics to build a unified risk dashboard.

Sedex provides an application programming interface that connects procurement platforms and business intelligence tools. Marks and Spencer extracts audit results, risk levels, and remediation progress directly into its internal systems. The Environmental Social and Corporate Governance committee reviews this combined data regularly. This dashboard displays real time supplier data alongside commercial metrics. The integration allows buyers to view assessment status and audit documentation in one location.

The Sedex platform analyzes over 100, 000 social audits to locate forced labor indicators. The system uses International Labour Organization research to calculate an audit indicator score for specific sites. Marks and Spencer integrates these scores with worker voice feedback from the Issara Partner Supplier Dashboard. In the 2022 to 2023 reporting period, SMETA audits identified five cases of forced labor indicators, such as compulsory overtime. By the 2024 to 2025 period, audits found three cases in the fashion and home supply chain.

Marks and Spencer publishes its tier one supply chain data on the Open Supply Hub. The Interactive Supply Chain Map allows the public to view factory locations and compliance status. The United Kingdom Government recognized this mapping tool as a valid example for managing modern slavery risks in public sector supply chains. The retailer covers the cost of the food safety and integrity audit for new suppliers. Follow up audits are charged to the supplier based on a standard rate card.

The company uses the Just Good Work application to inform seasonal workers about their rights. By May 2023, workers had downloaded this software 19, 000 times. The Safecall platform manages confidential reporting channels in multiple languages. The retailer reserves the right to reject audit findings if records appear fraudulent. The combination of Sedex data, SMETA audits, and direct worker feedback creates a verifiable record of supply chain conditions.

The Sedex Forced Labour Indicators tool operates within the risk assessment module. This system evaluates forced labor risks across four economic sectors, including agriculture, food processing, manufacturing, and logistics. The database covers 248 countries and cross

Retailers rely on predictive analytics and artificial intelligence to identify exploitation patterns. Traditional auditing methods depend on manual inspections. These physical checks leave blind spots across global supply chains. Marks and Spencer deploys the nGaje platform to collect direct worker feedback. During the 2023 to 2024 reporting period, 40, 807 participants across 361 sites submitted data through this system. Artificial intelligence processes this unstructured text to detect indicators of wage theft or forced labor.

Project AIMS evaluates modern slavery statements against legal requirements. Natural language processing scans thousands of documents to verify compliance. Retailers combine this textual analysis with predictive models. The software cross

The deployment of worker voice applications across the Marks and Spencer supply chain presents a clear metric for evaluating modern slavery detection. Between 2021 and 2025, the retailer shifted from relying exclusively on physical audits to integrating direct digital feedback. This transition provides verifiable data on the effectiveness of these platforms.

In the 2024 and 2025 reporting period, Marks and Spencer received 11 allegations linked to labour exploitation through its reporting channels, which include worker voice applications and the Modern Slavery Helpline. During the same period, the company recorded six violations related to forced labor, categorized under the standard that employment is freely chosen, within its food supply chain. This represents a decrease from 18 violations recorded in the 2023 and 2024 period. In the Fashion, Home, and Beauty division, auditors identified three violations in 2024 and 2025, down from four the previous year.

The catalyst for this digital integration was a 2021 Oxfam investigation. Researchers interviewed 390 workers in the United Kingdom and India, discovering that employees maintained an absence of trust in traditional reporting methods. Workers frequently felt inhibited when speaking to auditors in person, allowing serious workplace problems to go unreported. In response, Marks and Spencer scaled the nGaje application to reach over 500 food sites by 2022.

During an April 2024 session of the United Kingdom Parliament Modern Slavery Act 2015 Committee, experts discussed the utility of these applications. Representatives noted that tracking the exact number of modern slavery victims remains difficult. Instead, measuring the number of employees trained and the engagement rates on worker voice applications provides a verifiable metric for corporate compliance.

Yet, the technology presents specific limitations. Applications function as diagnostic tools rather than independent solutions. They require a prior culture of psychological safety. If factory management retaliates against workers, or if submitted comments receive no response, the digital platforms fail to generate accurate data. While the software can detect the payment of illegal recruitment fees or forced overtime, it cannot alter the commercial pressures and poverty wages that drive these conditions.

Worker voice applications do not mask the reality of modern slavery. They successfully expose violations that paper audits miss. They provide a direct line from the factory floor to the corporate boardroom. Also, they force suppliers to acknowledge worker sentiment through quantifiable data. The final verdict is that these digital platforms are highly at detecting exploitation, provided the purchasing brand commits to investigating and resolving the reported matters.
