ESRS S2-2 Value Chain Worker Engagement
ESRS S2-2 requires companies to disclose how they engage with value chain workers — the workers at their suppliers, subcontractors, and downstream business partners. Engaging with workers you do not directly employ, across multiple geographies and languages, is the most operationally complex element of ESRS S2.
ESRS S2-2 requires companies to disclose how they engage with value chain workers — the workers at their suppliers, subcontractors, and downstream business partners. ESRS S2-2 requires disclosure of: the processes used to engage with value chain workers about impacts that affect them; how the perspectives of value chain workers are taken into account; and what the company does when it cannot engage directly with value chain workers.
What ESRS S2-2 requires
ESRS S2-2 requires disclosure of: the processes used to engage with value chain workers about impacts that affect them; how the perspectives of value chain workers are taken into account; and what the company does when it cannot engage directly with value chain workers.
Direct engagement: Where feasible, direct engagement with workers at supplier sites — worker surveys, focus groups during audits, anonymous feedback mechanisms. Direct engagement provides the most authentic worker voice but is logistically challenging at scale across hundreds of suppliers.
Indirect engagement through representatives: Trade unions representing supply chain workers; NGOs working in supply chain communities; worker representative bodies at supplier sites; and multi-stakeholder initiatives that aggregate worker perspectives across industries.
Worker voice platforms: Technology solutions that enable supply chain workers to provide anonymous feedback directly to buyer companies — Ulula, Laborlink (now Laborvoices), Diginex WORK, and similar platforms that use SMS, mobile apps, or phone surveys to collect worker feedback at scale. These platforms provide a practical indirect engagement mechanism where direct access is limited.
Engagement in materiality assessment: ESRS 2 SBM-2 requires stakeholder engagement as an input to the double materiality assessment — value chain workers are key affected stakeholders for ESRS S2. Disclose how worker perspectives informed your S2 materiality conclusions — specifically which topics were elevated to material status based on worker input.
Worker engagement through social audits
Social audits are the primary mechanism through which large companies currently engage with supply chain workers — providing a structured format for worker interviews and facility assessment simultaneously.
Worker interview component: Credible social audits include confidential worker interviews — conducted off-site or in private spaces where workers cannot be identified by management. Standard audit protocols (SMETA, RBA VAP, SA8000) specify minimum worker interview numbers and question sets covering: pay and working hours compliance; freedom of association; working conditions; management behaviour; and whether workers feel safe raising concerns.
Limitations of audit-based worker engagement: Workers may not speak candidly during audits due to fear of management retaliation; audit sample sizes are typically small relative to total worker population; audit frequency (annual or biennial) provides only periodic snapshots; and pre-announced audits allow suppliers to present a better picture than normal operations.
For ESRS S2-2: disclose how worker interview findings from audits feed into your understanding of value chain worker impacts. Where worker interviews consistently reveal concerns — excessive overtime, wage deductions, restricted bathroom breaks — these are material S2 impacts that require action and disclosure, not just an audit finding.
Unannounced audits: Increasingly, leading companies conduct a percentage of audits without advance notice — allowing a more accurate picture of daily working conditions. Disclose whether any audits are unannounced and the proportion — this signals genuine commitment to accurate worker condition assessment beyond compliance theatre.
Building worker voice beyond audits
Audit-based worker engagement captures compliance against standards — it does not capture workers' own priorities, concerns, and voice. Building supplementary worker voice mechanisms provides richer insight into supply chain worker impacts.
SMS and mobile worker feedback: Platforms like Ulula deploy SMS-based surveys to supply chain workers in local languages — questions about working conditions, pay, safety, and management behaviour. Workers respond anonymously from personal phones. The data is aggregated and presented to buyer companies as a worker sentiment score with specific concern flags. This approach can reach workers in suppliers not yet audited and provides continuous rather than periodic data.
NGO engagement: Sector-focused NGOs (Clean Clothes Campaign, Business and Human Rights Resource Centre, Global Living Wage Coalition, Worker Rights Consortium) monitor supply chain conditions through their own research and worker testimony. Formal engagement with relevant NGOs — structured dialogue, joint risk assessment, shared learning — provides worker-centred input that audits miss. Disclose any formal NGO partnerships in your S2-2 engagement description.
Trade union engagement: Where unions represent workers in your supply chain, direct engagement with union representatives provides a legitimate worker voice channel. This is particularly relevant for food, garments, and automotive supply chains where unionisation rates are higher. Union engagement typically covers: collective agreement compliance; health and safety conditions; working time compliance; and freedom of association.
Engagement outcomes: S2-2 is not just a process disclosure — it requires showing that engagement produces insights that inform decisions. Cite specific examples where worker feedback changed your assessment of supply chain impacts or triggered supplier improvement actions.
Frequently asked questions
How do we engage with workers at tier 2 and beyond suppliers we have never visited?
Tier 2+ worker engagement is primarily achieved through intermediary organisations — NGOs monitoring those supply chain segments, trade unions with sector-wide representation, industry multi-stakeholder programmes. Satellite-based monitoring (for deforestation, land grabbing) and blockchain traceability tools provide evidence of conditions at remote tier 2 locations. Direct engagement is typically only feasible for tier 1.
Can we use our supplier's own worker satisfaction survey as evidence of S2-2 engagement?
With caveats. Supplier-conducted worker surveys may lack independence — workers may not respond candidly to surveys commissioned by their employer. Reference them as one data source but supplement with independent verification (social audit worker interviews, third-party worker voice platform data) to ensure credibility. Where supplier surveys show consistently high worker satisfaction, compare against independent audit findings — significant divergence suggests survey design or administration issues.
What languages must our worker engagement mechanisms support?
All languages spoken by workers in your material supply chain relationships. For a garment company sourcing from Bangladesh, Vietnam, and Cambodia, that means Bengali, Vietnamese, and Khmer at minimum. Language accessibility is a core requirement for genuine worker engagement — an English-only grievance hotline is inaccessible to most supply chain workers. Worker voice platform providers (Ulula, Laborvoices) offer multi-language capability as a core feature.
