Generally, the sales of shopping malls follow the morning and evening shifts, that is, early-late-early-late. The morning shift usually arrives at work about half an hour before the mall opens (according to the requirements of the mall), and ends at 3 to 4 pm, and the night shift lasts until the mall closes. Rest is usually a day from Monday to Friday. If there are few shop assistants, your shift can only last for one day. Similarly, you have to take a whole day off, so it doesn't matter how many people there are in the big store, it depends on how the manager arranges it.
