An audit tells a buyer what a site looked like on the day. WELL maps worker-driven findings to the UNGP and ILO frameworks buyers already report against — so worker voice becomes evidence they can put their name to.

"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.

From 14 Dec 2027, the EU will bar any product made with forced labour—at any stage, even in part. The new guidelines make this an obligation of result: prove your product is clean, fast. With only 30 working days to respond, the evidence that matters most is worker-held and confidential—testimonies, surveys, and grievance records a site can’t stage.

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.

CBP's June 2026 guidance consolidates forced labor enforcement under three legal authorities and raises the evidentiary bar to clear and convincing. The primary evidence it points to is held by workers — here is how to build a record that holds at the border.
