As a hotel security guard, do you have the right to check employees' bags? (under the condition that employees are required to open it themselves)? Is this illegal?

First, without the right of inspection, even the police have to apply for a search warrant in the procuratorate.

Second, in order to ensure personal privacy and property safety, employees have the right to refuse your request to open your handbag (at most, you can only ask).

Solution: Employees can store, pack, pick up or unpack after work.

Your leader means to suspect that everyone has something to steal. Be careful yourself. Someone may still be watching you. The man who can do such a thing is a villain. If I was killed, I wouldn't work for him either. If someone really sues for infringement, you can come forward yourself. Your leader generally won't admit it.
