The waiting time of a worker is not necessarily recognized as his compensable working time. Major Taiwanese authors on this topic admit the standby time should be compensable working time. The idea is that working time is considered as the time a worker controlled and directed under an employer. If a worker turns his labor at employer's disposal it will constitute a working status. Therefore, a standby time is the time a worker is already under his employer's direction but he is inactive. The time spent for standby duty should be included as part of working time. By numerous decisions, Taiwanese courts has established three rules that shall be applicable to tell whether a waiting time is a standby time and compensable from non-working time. The first rule is to learn from the language of employment agreement to decide how the parties want the time to be decided. The second rule is based on the fact whether the employee is retained in the employer's premise. The third rule is based on the fact whether the waiting time is required by the employer. However, in Taiwanese court’s idea, when a worker is simply inactive to engage the waiting is not considered that he is working.
