It mainly depends on how many classes you work in the hotel. If there are two shifts, it is usually continuous work 12 hours.
There is no exact regulation on the working hours of the hotel front desk. For example, the day shift is from 8 am to 8 pm, and the night shift is from 8 pm to 8 am. Some good hotels, such as five-star hotels, are divided into morning shift, afternoon shift and night shift, that is, eight-hour shift in the morning, noon shift and evening shift.
