I was just thinking about this very topic yesterday. I was watching Loose women on TV and they were discussing how women nowadays can have everything, family, career etc etc..yeh right!!!!
One of our main problems is that we live on the border of two authorities, eldest 2 children go to school in one authority and youngest two (sen child plus 1 other)in a neighbouring authority, and they often have school holiday different dates...so makes childcare even more complicated. Some people would say well you shouldn't have had four children, we didn't choose to, we merged two families so became a family this size.
In fact I don't work other than as DH's unpaid PA for his self employment as we couldn't arrange holiday arrangements for 4 children (and I don't know about your schools but ours seem to send them home with the smallest of sniffle and so we do have to have one of us available year round for the "emergency" pick up calls. I am sure when we were at school we were put in the secretarys office on a little camp bed for an hour and then sent back to class (or sent home if really ill and been observed for a while) now they send them home at the slightest sniffle it seems.)
DH also works part time for Education authority and when youngest 2 change to High school this Sept we will have all four children in same authority but DH in other one still, so I will have the fun of all four in school hols as he will be working. I just don't get why school holidays can't be the same countywide??
OP - I would def try to see if the school could at least consider making some holiday club, if not for the full hols maybe for half so all the parents could use some leave but not have to take unpaid. Its a joke local authorities saying its not their problem, we are constantly made to feel like everyone should be in work, but there is still so little support in helping parents to be able to realistically work. With a general election loaming there are bound to be lots of promises...AGAIN!!!
