it doesn't go so well you can at least spend the time after doing something to cheer yourself up! If the interview was really short notice or if I didn't have any leave left I'd go for an appointment with BT repairman or something. I'd avoid taking it off sick, not only is it unethical but most employers ask for your sick record as part of references so if you end up being successful it doesn't make any sense to artificially inflate the number of sick days you've taken. No, the idea is that you say you're going to the dentist's, when actually you're going for an interview. But the boss may wonder why you're so smart (in reality for the interview), but you've laid the ground nicely by saying you feel the need to be smart to go to the dentist's, for whatever reason. It depends on your workplace, your boss, and how desperate you are to leave you job. Waiting in for a repairman works for a one-off, but there may be an expectation you'll be working from home, and therefore contactable.If you reallt don't get one with your boss, then it's highly likely you'll be applying for lots of things at once, so need to lay the ground for possible attendance at a number of interviews in a short space of time. If you don't have the kind of relationship with your manager where you can be honest about the interview - and very few people do
