here, I understand that the duty you asked is normal working hours: the duty arrangement for supervisors in front-line departments is generally implemented according to administrative classes; According to the different business conditions of each store, the time is slightly different. For example, the supervisor of the front office, because the guests arrive at the store late, the duty time of the general supervisor is postponed by 3 to 4 hours compared with the administrative class; The same is true of the duty time of the head of the food and beverage department. However, the supervisor of the housekeeping department is on duty about 2 hours earlier than the administrative class.
