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.

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.
