Supplier staff turnover: what should UK buyers do?

Treat repeated staff turnover as a production-control risk. Ask for named cover for critical roles, task-specific training records and observed proof of competence. Agree extra checks and shipment release conditions for batches made by replacement teams. Cambridge China Bridge can help through its own staff in China.

Find which work has lost experienced cover

Ask the supplier which production and quality roles have changed, when the changes took effect and which products, lines and shifts are affected. Focus on work where mistakes can escape later inspection: machine setup, material identification, joining, test operation and final release. Compare the change dates with defects and rework. The quality drift guide covers the wider defect response.

Request a role-coverage record naming the current operator, competent deputy, supervisor and person authorised by the factory to release the work. Check cover across shifts and absences. Ask management why turnover keeps recurring and what it is doing to retain capability. Agree advance notification of critical-role changes and a hold on affected work when competent cover is unavailable.

Check what the training records actually prove

Request task-specific records showing the worker identifier, training date, trainer, instruction revision, equipment used, assessment result and authorisation to work independently. Match them to the people currently assigned to your order. Use identifiers where names are unnecessary; avoid requesting unrelated personnel files.

A signed attendance sheet shows attendance, but does not demonstrate that someone can perform the task. Check that training uses the current specification, approved defect examples and actual test method. Ask how temporary workers, reassigned operators and replacement inspectors are assessed, supervised and retrained when instructions change.

Observe competence on your actual product

Have replacement operators demonstrate setup and production using the intended materials, equipment and instructions. Ask them to explain critical settings, recognise a defect and show what happens when a result is outside the limit. Keep unfamiliar operators supervised until the factory's assessor records a satisfactory practical assessment.

Assess inspectors separately. Use labelled reference samples with known acceptable and unacceptable features, and compare their decisions with the agreed standard. Observe measurement technique, test setup, recording and segregation of failed goods. Record who assessed each task and any remaining restrictions; a manager's reassurance should not replace witnessed results.

Add checks to replacement-team batches

Agree the enhanced inspection plan before the replacement team starts. Check setup output, inspect during production and review finished goods before shipment. Target the operations affected by staff changes, including safety-related work and defects previously missed. State the sampling method, additional functional checks, acceptance limits and response to failure. The during-production inspection guide explains how to brief the visit.

Identify affected batches by team, shift, line and production date, and keep suspect goods separate pending review. Ask for original test and rework records, rather than a summary saying the batch passed. Use the supplier batch traceability guide to connect those records. Agree who can release shipment and what evidence that person must receive.

Set conditions for returning to routine checks

Before production, agree what will justify removing extra checks: satisfactory practical assessments, stable results across affected shifts, resolved recurring defects and reliable deputy cover. Review actual batch evidence against those conditions. If failures recur or records cannot be verified, hold affected shipments, request corrective action and consider qualifying another supplier.

UK product-safety guidance states that you remain responsible for a product's safety after it has been placed on the market. When changed workmanship could affect safety, ask your product-compliance adviser which checks need repeating before release. Cambridge China Bridge's staff in China can help check role coverage, witness practical demonstrations and inspect affected batches against your agreed brief.

Frequently asked questions

Should I stop orders when factory staff keep leaving?

Assess the affected tasks first. Hold work or shipment where competent cover or reliable checks are missing. Resume against agreed evidence, rather than a promise that replacements have been hired.

What training records should I ask a supplier for?

Ask for task-specific records linking current workers to the instruction revision, trainer, practical assessment, result and authorisation to work independently.

How can I check replacement inspectors are competent?

Observe them using the agreed method on reference samples with known defects. Check their decisions, measurement technique, records and handling of failed goods.

When can I remove extra batch inspections?

When the agreed evidence shows competent operators and deputies, stable results across affected shifts and resolved recurring defects. Record the buyer's approval to return to routine checks.
