Verifying overtime records

Key takeaways

1. Define the audit scope in writing before the visit, because a factory that knows the checkpoints prepares evidence while one kept guessing stages theater.
2. Triangulate every important claim across documents, observation, and interviews — a single source of evidence is an anecdote, not a finding.
3. Separate system findings from one-off lapses in the report, since only systemic gaps predict how the next order will run.
4. Close every corrective action with evidence and a deadline, and verify closure on the next visit rather than accepting paper promises.
5. Treat worker interviews as sampling, not interrogation: small, random, private conversations reveal whether procedures live on the floor or only in binders.

Overtime auditing connects labor standards to production reality: hours data constrains output claims, output data constrains hours claims, and pay data must satisfy both. The triangle either closes cleanly or exposes the fabrication.

A useful audit answers one commercial question — should this factory make our goods, and under what conditions? Every checkpoint, interview, and document request should trace back to that question, or it is audit theater.

Chinese factories vary enormously in how they receive auditors: some treat the visit as collaboration, others as inspection to be survived. The buyer's preparation — scope clarity, seniority of the contact, document requests sent ahead — sets which version arrives.

Limits, premiums, consent

Monthly and daily hour limits set the ceiling: auditors reconstruct actual hours from attendance traces and compare against statutory caps for the locality and period. Systematic exceedance across sampled months is a system finding, not a seasonal excuse.

Premium math follows: overtime hours must be paid at the uplifted rates the law requires, applied to the correct wage base. Common failures include flat-rate overtime, premiums on minimum wage while actual base is higher, and piece-rate systems with no premium layer at all.

Voluntariness and consent complete the picture: overtime must be voluntary with documented worker agreement, and pregnant, nursing, or juvenile protections observed where applicable. Coerced overtime documented as voluntary fails twice — hours and honesty. The WTO TBT Agreement frames the bigger picture: technical regulations should not create unnecessary obstacles to trade, which is why documented evidence of conformity smooths market access.^[1]

How the audit day runs

The day opens with scope confirmation: which areas are in bounds, which records will be pulled, who must be available for interviews, and what happens if access is refused. Factories that agreed all this in writing cooperate; factories meeting it for the first time negotiate, and the audit loses its first hour.

The walkthrough follows the product flow rather than the org chart — incoming material, storage, production lines, testing stations, packing, finished-goods warehouse. Flow-following surfaces handoff gaps that department tours politely skip. In practice, an independent supplier verification checks licenses, capacity, and quality systems before the buyer commits volume.

Document review runs in parallel with observation wherever staffing allows: licenses and certificates, quality manuals, recent production and QC records, corrective logs. Dates, signatures, and consistency across documents matter more than the polish of any single binder. RoHS thinking shapes the materials checkpoint: identify the homogeneous materials, know which restricted substances each one risks carrying, and test accordingly.^[2]

Overtime evidence checks

All four legs need passing grades; strength in three never compensates fabrication in the fourth.

After the visit: from report to decision

Conditional approval is the normal outcome for developing factories: specific gaps, named owners, dated evidence of closure. Release order volume in stages tied to closure milestones rather than all at once on promises.

A rejection should name the re-entry path. Factories improve, and a buyer who states exactly what must change — with what evidence, by when — keeps a future option open while protecting the current season.

Share the corrective section with the factory promptly and require a dated response plan. Audit value decays fast: findings delivered weeks later meet changed personnel and faded memory, and closure rates collapse.

Senior factory attendance at the opening meeting predicts cooperation quality all day. When the owner or general manager attends, records appear faster and awkward areas open sooner; when only a junior handler appears, expect a managed tour.

Photograph the mundane, not just the violations: calibration labels, posted procedures, training boards, maintenance logs. Normal-state evidence is what future disputes need, and nobody photographs it twice.

Language discipline matters during interviews. Questions route through the auditor's interpreter, never through factory management, and answers are recorded privately. Relayed interviews through interested parties are not evidence.

Evening factory-dormitory observations, where the scope includes them, reveal working-hour realities that daytime records may disguise. Entry and exit patterns at shift change are hard to stage and easy to read.

Subcontracting discovered mid-audit should be mapped immediately: which processes, where performed, under whose control. Undisclosed outsourcing found by accident usually indicates more undisclosed outsourcing not yet found.
