During the period of the business trip, the employee is considered to have worked the deemed working hours.
However, if your supervisor instructs you to work overtime or you request overtime, and your actual working hours on the day (excluding travel time from home to the destination and back, breaks during the trip, etc.) exceed the prescribed working hours, you must apply for overtime.
*The HR website has a document on the rules for applying for overtime and attendance during travel days.
