1. Set Appropriate Fixed Overtime Hours
Establish realistic fixed overtime hours based on average overtime patterns. Setting hours too high results in unnecessary labor costs, while setting them too low fails to reduce administrative efforts for additional overtime calculations. If there is significant monthly variation in overtime, this system may not be suitable.
Moreover, as work-life balance gains prominence, long overtime hours are increasingly scrutinized, so care must be taken.
2. Establish and Communicate Clear Rules
Detail the rules for the fixed overtime pay system in employment regulations and communicate them to employees. This includes clearly specifying the fixed overtime hours and corresponding pay amounts. Since pay structures may vary among employees, ensure the calculation methods are documented in salary regulations.
It is also critical to distinguish fixed overtime pay from base pay in pay slips. Avoid vague terms such as “management allowance” when labeling fixed overtime, as this may result in legal challenges and incorrect base pay calculations.
3. Conduct Proper Time Management and Pay Additional Overtime
Even under the fixed overtime system, employers must manage attendance and compensate for any overtime beyond the fixed hours. Employers have a legal obligation to accurately track employee working hours. Refer to government-issued guidelines when necessary:

Provide education and training to personnel managers to ensure correct application of the system. Mismanagement can lead to illegal practices such as unpaid overtime. Additionally, foster a workplace culture that does not normalize excessive overtime simply because it is pre-paid.
