The EU Forced Labour Regulation Sets an Obligation of Result — and Worker Evidence Is How You Meet It

The EU decided the test. Workers hold the proof.

On 26 June 2026, the European Commission published the implementation guidelines for the EU Forced Labour Regulation (Regulation (EU) 2024/3015), alongside the new Forced Labour Single Portal. From 14 December 2027, any product made with forced labour — in whole or in part, at any stage — is barred from the EU market, regardless of a company's size or sector. Read closely, the Regulation turns on a single question: can a company demonstrate that its product is clean? The evidence that answers it is held by workers.

What the EU Forced Labour Regulation actually requires

The Forced Labour Regulation is not a due diligence law. It sets an obligation of result — a product free of forced labour — and leaves the method of meeting it to the company. The guidelines are explicit that the Regulation imposes no due diligence obligation beyond what already exists in EU or national law. Due diligence is not mandated; it is how a company reaches the result and shows it has.

That distinction governs enforcement. Cases are decided by public authorities, who carry the burden of proof, through a preliminary phase in which a company has 30 working days to respond to a request for information. The guidelines describe full, timely cooperation in that window as the best way to allay an authority's concern before a formal investigation opens. Thirty working days rewards the company that already holds an organised, credible record — and exposes the one that has to assemble it under pressure.

Which companies come under scrutiny in the first place is risk-based — screened by sector, geography, volume and the share of a suspect input — and will sharpen once the European Union's upcoming public database on forced labour risks goes live, naming the sectors and geographies authorities will focus on first.

No single method is prescribed. But the guidelines are specific about the evidence that carries weight: worker interview transcripts and testimonies, surveys run by trade unions or worker representatives, and records from grievance mechanisms are all named among the information an authority may draw on. On method, the guidelines state that workers should be interviewed by trusted third parties to protect confidentiality and safety.

The evidence that survives scrutiny is the evidence a site cannot stage

The logic is consistent throughout. The strongest evidence of conditions in a value chain is what workers themselves report — confidentially, to someone the site does not control. It is the one input a site cannot prepare in advance.

This is where most programmes are thin, and where a common assumption fails. A grievance mechanism can exist on paper, be documented, and still say nothing about whether workers can reach it, trust it, or see anything change when they raise a concern. Existence is not effectiveness. Under an obligation of result, that difference is the exposure — and only workers can evidence it.

What it looks like when evidence is built: 50 sites

Consider what that record looks like in practice. A global electronics buyer ran Labor Solutions' WELL Grievance Integrity program — our framework for assessing grievance mechanisms against the UN Guiding Principles' effectiveness criteria, run inside the WELL Cycle — across 50 strategic and high-risk manufacturing sites in six countries, reaching more than 80,000 workers.

On paper, the mechanisms existed. Two Operational Grievance Mechanisms, one in-house and one third-party, had received fewer than 20 worker cases across an entire year from all strategic sites combined. Low volume is easy to read as low risk. It is more often a signal that workers cannot access the channel or do not trust it — and that reading only comes from asking them.

The WELL Worker Survey did. More than 65% of workers responded — a rate that itself signals readiness to speak when a trusted channel exists. Workers reported that they did not know how to seek help outside the company, that management rarely acted on feedback, and that formal channels were out of reach. WELL Grievance Integrity mapped those findings against all eight UNGP Principle 31 effectiveness criteria; the WELL Self-Diagnostic Tool then examined the management competency behind each gap — not whether a procedure existed, but whether supervisors handle reports without retaliation and whether feedback loops close. Each site received a WELL Action Plan.

Six months on, 83% of sites had completed their assigned actions — manager training on grievance handling, more worker-centric reporting channels, and communicating external grievance options back to workers — and 72% had advanced a maturity level. The buyer now holds, per site, a criterion-by-criterion record of what workers experienced, the competency gap behind it, and the action taken to close it.

That is the shape of an obligation-of-result record: not a snapshot, but a standing, improving account, grounded in worker evidence and documented over time. It is what the WELL Cycle produces each year as WELL Intelligence — a body of evidence that deepens with every stage and compounds because the cycle repeats.

Three frameworks that point in one direction

The EU is not moving alone. CBP's June 2026 forced labor guidance names stakeholder engagement first among its eight due-diligence elements. The UN Guiding Principles have set the expectation since 2011 — the responsibility to respect turns on meaningful consultation with affected workers (Principles 18 and 19, Pillar 2), and the effectiveness of a grievance mechanism (Principle 31, Access to Remedy) can only be established by asking workers directly. CSDDD and ESRS S2 build on the same architecture. The capability that answers one answers them all: a worker-grounded, criterion-level record of what is happening and what has been done about it.

The next step

The Regulation did not change what credible due diligence looks like. It changed the cost of not holding the evidence — and set a 30-working-day clock on producing it. The question worth testing now is a simple one: if an authority asked today, could you show what workers themselves report about the risks in your value chain, and what you did in response? Where the answer is not yet, the place to start is where the WELL Cycle starts — by listening.
