Standard work time

Hong Kong's standard work time is set at 40 hours per week. This regulation establishes the baseline maximum working hours that employers must observe when scheduling employees, though the Employment Ordinance does not mandate a specific daily or weekly structure provided the total does not exceed this threshold. The standard work time applies across most employment sectors and serves as the reference point for calculating overtime compensation and determining whether additional hours qualify as overtime work.

The rule is governed by the Employment Ordinance, the primary legislation administered by the Labour Department under Hong Kong's government. The Ordinance sets out comprehensive employment protections, including provisions on working hours, rest days, and statutory holidays.

Effective June 7, 2026, Hong Kong introduced a Heat Stress at Work Warning system requiring mandatory heat stroke prevention measures. This new requirement complements existing working hour regulations by imposing additional obligations on employers to monitor heat conditions and implement protective measures during high-temperature periods, potentially affecting how work time is structured in outdoor or high-heat environments.

Employers and payroll teams must ensure that scheduled working hours do not exceed 40 hours per week on a regular basis. Any hours worked beyond this threshold typically trigger overtime payment obligations at rates specified in employment contracts or by statutory minimum. From June 2026 onwards, employers must also integrate heat stress prevention protocols into their work scheduling practices, particularly for roles involving outdoor work or exposure to high temperatures, to comply with the new warning system requirements.
