Many jobs do not ask already. If you are not going to be there, you are not going to be there. A reason does not change the fact you will not be there. There is no reason for them to know. They will just use it against you. I am not able to make it to work today. Why? I will not be there. If they push back and you feel compelled to say anything, “Your question is a violation of my HIIPA rights.”
