On the whole, China adopts a standard system of eight-hour workdays and 40-hour work weeks.

If the standard system cannot be implemented due to limitations resulting from the nature of the work or the characteristics of production, systems of irregular working hours and comprehensive working hour calculation are permissible upon approval.

Employers shall ensure that their employed laborers have at least one day off every week. To meet the needs of production and operation, employers are allowed to extend their employees' working hours following consultation with the trade union and with the employee.

The extended working time is generally not to exceed one hour per day; if employers need to further extend working hours under special circumstances, the extended working time shall not exceed  three hours per day or 36 hours per month in total; furthermore, extended working hours are only allowable on the condition that they do not harm the health of employees.
