A new prospective job has called me for an interview this coming Monday, which is too soon to give my job notice that I need to be out. The interview is at 3pm and I work 8-430pm. I just had a doctor's appointment this week so if I say it's for the doctor they won't believe me and might ask for documentation. What's an excuse I can use to leave? I'd have to leave by at the earliest 130pm.
