jambo - they're not talking about the teachers covering the extra hours. In fact it could be the opposite, that the after school clubs would run some of the activities which are offered now after school by teachers. Calling it an "extended school day" rather than "offering coordinated wraparound care" is giving that impression, but as always it's all down to the spin isn't it?
tbh I wouldn't actually expect that many people to use it to it's full 8-6 extent, but jobs which fit in with 9-3 termtime only hours - especially jobs which actually pay a reasonable rate - are in such short supply that a lot of us are forced into having to make other arrangements for our children for at least some of that out-of-school time.
It's really not a nice cosy black vs white argument of kids at home with mum vs forcing them into a long school day, but an extra dimension to the grey area that exisits now with a hotchpotch of juggling working hours, childminders, alternating days with neighbours if you're lucky, grandparents if you're fortunate enough to have them locally and not still working themselves (and face it - for most people that's not an option) or whatever.
As a parent of a child coming up to school age, and discovering that although the local school does have an after school club it's so oversubscribed that for a child without an elder sibling already attending it they're unlikely to get a place for the first four years and that the local early years department doesn't know of any childminders who will do pick up or drop off to the school what are we left with? Abandon working (which we can ill afford to do), look for a part time job instead (but that would probably mean only 1/4 the pay for half the hours), work evening/weekends to make up the hours, take on an au pair purely to do the school pickup/ after school, or pay for a private school simply because it can offer this kind of wraparound care? None of them are really great options are they?
And I don't really get the argument that having before/after school clubs would cut down the child's time with the family. Surely if we have to juggle our work hours so that one of us works normal days and the other evenings and weekends then what they get is a kind of serial one-parent family, rather than ever getting a "family life" as such? Or should we to rearrange things so that one of us can start and finish early (and that means starting work before 7 am to finish in time for the end of school) and the other start late to do drop offs (so not finishing until at least 6.30) and not seeing the children awake all week? Believe me, I've done the "don't see them awake between Sunday bedtime and getting up the following Saturday morning" thing and it's no fun.
