Before anyone bites my head off, I do know that teachers do a lot of work evenings and holidays. I know it's not knock off at 3pm every day and 13 weeks a year off
and that term-time, especially as an NQT is going to be hellish. I think it is worth it in the long run for a job I would enjoy that would have things like a pension and some security (neither or which I have no)
I am an LP so childcare (for small but school age kids) is an issue. I would rather work FT and enjoy better career prospects and am under no delusions about the work-levels/politics/being-blamed-for-all-society's-ill aspects of teaching. I have done a lot of training and instructing and have repeatedly been told I have a talent for explaining things and a good way of enthusing trainees. I was going to apply 5 years ago but was talked out of it by (nowX)H 
How much time should I factor in for paid childcare over the holidays?Obviously there are planning meetings etc but I have no idea what I am budgeting for. I've asked teacher friends and it seems to vary and I guess depends on your school and HT too.
