I work voluntarily in a hospice. It was originally just to gain experience to get into Uni. Anyway when I first started I had a car and a partner to watch the kids. Now I don't have either. The original shift was on a Sunday and I called the manager and said there was no way I could get in on a sunday anymore as I have no car or childcare so she squeezed me into a wednesday afternoon. I agreed but I've been thinking about it and it's going to be a hell of a lot of faffing. Basically I'll have to zoom straight there after college at 12pm on the wednesday lunch time. Then I finish at 5pm, the busses around there are awful and very few so Id need to get a bus back to the city centre (rush hour in big city, this will take at least 45 mins) and then a bus from the city centre to home (we're talking 6pm now - prime rush hour) this will took another hour. I'm not going to get home until 6.30-6.40pm which means the kids won't get their dinner until gone 7pm. it also means they're going to be on their own from 4pm until gone 6pm and the youngest is only 11.
It seems like a hell of a lot of faffing about for a voluntary job?! Or am I being lazy?? AIBU to call her back and say I can't do it even though I initially agreed to it?
