I've been invited to an induction day at the school I'll be teaching in come September. It involves a full day at the school. My current school are being a bit unhelpful, telling me that I have to take the day unpaid unless the new school pays for my supply cover. I'm wondering what usual practice is? My new school seems to think the old school should foot the bill, but the school bursar at my current place is being extremely rude about it (she's a bit of a nightmare in general and not pleasant to deal with). I don't mind what the rule is and who pays, but I'm being put rather in the middle and am having to email back and forth between the two schools. When I asked 'my' school bursar to contact the new school directly to work it out, she went mental. Help?
