Can supplier workers raise concerns safely?

Ask workers privately how they would report a concern, check that the route works without a supervisor, and trace how identities and complaints are handled. Look for evidence of remedies and protection from retaliation, rather than accepting a policy alone. Agree the scope of checks with Cambridge China Bridge.

Start with worker access, not the audit badge

The Home Office guidance says workers should have access to anonymous reporting mechanisms in a language they understand. Use that as a starting point for checking the actual production site. Our ethical audit guide covers audit selection and scope; this check asks whether workers can safely speak up between visits.

Ask the supplier to show every reporting route, who receives concerns and which workers can use it. Include agency staff, temporary workers and workers at subcontracted sites. Request the instructions workers actually receive, rather than a policy prepared for buyers.

Check that workers can use the channels

With the worker’s agreement, ask privately how they would raise a concern about their supervisor. Avoid manager-selected interviewees and interpreters who report to the person complained about. Let workers decline. Ask which route they trust, whether it costs them anything and whether they can use it away from management observation.

Check language, reading ability, phone access and availability across shifts. A mobile channel is weak if workers need a company login or permission to use a phone. A suggestion box is weak if collecting or posting a complaint exposes the worker. Ask for an alternative route outside the supervisor’s control, then test it using a clearly labelled test enquiry.

Separate anonymity from confidentiality

Anonymous reporting means the worker does not give their identity. Confidential reporting means an identity may be known but access is restricted. Ask what the system records, who can see it and whether names, phone details or message histories reach factory management. Do not promise anonymity before checking these details.

Agree a safe contact method with the worker before follow-up. Explain who may need information and any limits on confidentiality before collecting it. Share only what is needed to address the concern. Remove identifying details from buyer reports, including combinations of shift, job and incident details that could reveal the speaker.

Look for retaliation after a complaint

Ask what happens if the complaint concerns the person who normally receives reports. Seek a route that bypasses that person and a named owner for protection and follow-up. Ask workers privately about threats, reduced shifts, lost overtime, transfers, dismissal or pressure to withdraw a complaint.

Review anonymised complaint histories alongside outcomes and follow-up records. An empty log does not establish safe conditions: workers may distrust the process. If retaliation is suspected, avoid sending allegations straight to the accused manager. Agree a protection plan and involve a suitably experienced independent specialist where needed.

Follow the concern through to a remedy

Ask to trace an anonymised case from receipt through investigation, action and worker feedback. Check who owns it, how the worker receives updates, how an unsatisfactory response can be challenged and whether the underlying problem changed. Use the corrective action closure guide to assess supporting evidence without exposing the complainant.

Record each channel’s weaknesses, the agreed improvements, the responsible person and when you will review them. Keep sensitive case material separate from routine order records. Build private worker access into the scope of your factory assessment. Cambridge China Bridge’s own staff in China can help coordinate site checks; agree any specialist worker-protection work separately.

Frequently asked questions

Is a supplier grievance policy enough?

No. Check whether workers know the routes, can use them privately and receive a response. Ask for anonymised case outcomes and safe worker feedback.

Does confidential reporting mean anonymous?

No. Confidential reporting may identify the worker to the handler. Anonymous reporting avoids giving an identity. Check what the channel records and who can access it.

What if the factory has no worker complaints?

Treat the absence of complaints as a question to investigate. Check awareness, access and trust privately before drawing conclusions about working conditions.

What should I do if a worker fears retaliation?

Agree a safe contact method, restrict identifying information and avoid confronting the accused manager without a protection plan. Seek experienced independent help where needed.
