"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.

Regulation stops at Tier 1. Exposure sits upstream. What a working Tier 2 grievance mechanism has to evidence — under CSDDD, LkSG, and the EU Forced Labour Regulation — and why buyers are already moving there.

At its 50th anniversary, the OECD reported more workers seeking remedy directly than ever before. But a grievance mechanism that exists on paper isn't one that works — and only workers can tell you the difference. What the shift to remedy means for due diligence, and how worker voice evidences all eight UNGP Principle 31 criteria.

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.

Open Supply Hub has launched OS Hub Spotlight — a new offering connecting siloed datasets to production facility profiles. Labor Solutions joins as a founding partner, making WOVO Connect operational grievance mechanism data discoverable across OS Hub's open platform. For the first time, brands, suppliers, and civil society organisations can systematically map grievance mechanism coverage at the facility level — a critical step toward meeting CSDDD, LkSG, and UNGP due diligen

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

Most suppliers have a grievance mechanism. The harder question is whether workers trust it enough to use it — and whether buyers know how to read what they see. Zero grievances rarely means zero problems. It often means workers don't feel safe speaking up. This article breaks down what effective operational grievance mechanisms look like, why utilization is the metric that matters, and how buyers can assess supplier systems with confidence.
