That's true, because every Saturday and Sunday is the rest day for students and staff of some enterprises. Like those who have consumption conditions, they usually choose to take their children to restaurants on weekends, which is not only to spend time with their loved ones and children, but also to relax themselves. This period is also the busiest time in the catering industry, and families spend more. At this time, bosses or managers generally don't grant leave unless there are special circumstances (such as physical illness such as a cold and fever). As a manager, what he/she considers is how to distribute the labor force when there are many customers and there are not enough people: one more person, one more strength, which will reduce the labor intensity of other employees, on the contrary, it will increase the labor intensity of other employees. As a way to deduct money, if the contract stipulates that you will not break the law if you want, as for how much to deduct, you need to read the contract carefully. If you sign it, you should be careful not to ask for leave unless there is anything special in the future. I want to tell you that it is possible for any industry to set the rest day on Saturday and weekend (what I said is possible, not certain), and the catering industry will definitely not. Even if there is, it will be in a bad business situation.
