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.

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.

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

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.
