3-shift factories — overtime is daily business. China and Vietnam limit it differently: hour caps, allowances, peak-season flexibility. This article compares the legal frameworks. Chinese-law details are for reference only — check current texts.
1. Overtime caps: each country’s framework

- Know the caps: checking current overtime caps in the operating country — daily, monthly and annual — and encoding them into the scheduling system so violations become impossible rather than merely discouraged;
- Schedule smart: designing 3-shift rosters that stay within caps even in peak season — using seasonal hires and outsourcing as buffers instead of stretching legal limits;
- Pay correctly: computing overtime and night-shift allowances at the right rates — weekday, rest-day and holiday differentials applied accurately and paid on time;
- Record everything: keeping complete electronic timekeeping records with worker sign-off — the single best defence in any labour inspection or dispute;
- Care for people: protecting night-shift health with checkups, meals, transport and fair rotation — healthy workers are productive workers, and the law increasingly says so too;
- Keep improving: reviewing shift patterns, costs and worker feedback regularly — the compliant factory is not a one-time project but a permanent discipline.
