If you are in poor health and work in the property, you are required to be on duty twice a week. How can you not be on duty? what can I say?

Hello, there are usually two possibilities in your situation:

If you are not seriously ill, you have to be on duty, but if you have a cold and fever, the general unit will allow you to take a break once or twice, and it is impossible to take a break all the time.

If you have any special disease, after telling the company, the company will definitely ask you to treat it first, so this is the possibility that you will lose this position.

Generally, there are only two possibilities, because being on duty is the company's rule, and everyone is on duty, so it is impossible to be special for you alone.
