"It exists" is not "it works." This case study follows how one electronics manufacturing site used worker voice to find where confidence in its grievance mechanism was breaking down — and rebuilt it, step by step, through the WELL Grievance Integrity Program.

Across 50 sites and 80,000+ workers, WELL Grievance Integrity assessed grievance mechanisms against all eight UNGP Principle 31 criteria — and produced the site-level, worker-grounded evidence CSDDD and ESRS S2 now require. 83% of actions closed, 72% advanced a maturity level.

Worker voice is a worker's ability to influence the conditions of their own working life. Not to be surveyed. Not to be consulted. Not to have a hotline to call. To influence outcomes. Most companies built their human rights due diligence around social compliance audits — by habit, not legal requirement. CSDDD, LkSG, and France's Duty of Vigilance Law require worker participation and access to remedy. The legislation was built around workers. The industry built its response

This case study shows how a pilot of the WELL Survey in the seafood industry validated its ability to capture worker voice, surface sector-specific risks, and generate actionable insights for seafood supply chains.
