"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

CSDDD, LkSG, and France's Duty of Vigilance Law do not require audits. They require worker engagement. Here is the regulatory, risk management, supplier ROI, and board-level evidence — and what to say to the people in your organization who are not yet convinced.

CSDDD requires ongoing worker engagement — not a one-time survey. Here’s what the annual Worker-Driven Due Diligence cycle looks like in practice: four stages, run in sequence, every year, because human rights is a practice, not a project.

adidas submitted 47,200 worker grievances in 2025 — up 32% — with a 99% resolution rate and 79% satisfaction. Here's why rising complaint volume is the strongest signal of a CSDDD-compliant program, and what six years of WOVO data proves.

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.
