I'm a teacher in secondary school, and we do visit days every Saturday for Year 5 students at local primaries. Departments take turns to run them, and they've just announced that ours will be this weekend (nothing like notice, right?). Lots of people in the department have young children, so can't drop everything and come in on short notice, so the deputy head has said that he's relying on those of us who don't to come on in.
I initially told him I wouldn't be able to, as I'm a carer to two family members every Saturday to give other family some respite, since they do all week when I am working. He said that was fine, and he'd asked others.
Anyway, he came and found me today and told me that he is still a member of staff short, so I'd HAVE to come in, or he'll have to cancel the whole thing. He kind of caught me by surprise, so I said I would ring family and ask if someone could cover me so I could come in. I'll probably still do this in a mo.
But AIBU to really not want to? I look forward to seeing my family on the weekend, and I feel bad that I'd have to get somebody else to look after them, when I should be able to just do it myself. AIBU to say no?
