Kids here finish school at 1, sometimes earlier. I often wonder how its going to be when my LO goes to school and how it will be for me work wise. I have no idea what kind of job I can get that's 8-12. Not to mention school holidays and such.
I dont think making them longer will help at all - bad idea. But making the shorter would surely affect how parents can work.
School, education as a whole, isn't a childcare service though. I accept that it's useful having your child at school so people can work and not have to pay for childcare in that time, but i
t's not education's job to work around parent's hours.
I think our current school days are too long for 5 years olds. 6 hours is an awfully long time for a young child to be expected to behave and concentrate.
