I've recently been offered a new job which requires me to undergo a medical assessment before getting a start date. My current employers do not know I'm planning to leave. We get paid time off for medical appointments, WIBU to take the afternoon off (appointment an hours drive away) even though I'm not actually sick? I have no annual leave left to take so would have to take unpaid holiday otherwise. The appointment cannot be rearranged as they are open the same hours I work!
