Emily grin - no, we both work in schools and I assure you dh goes back on the 2nd (I go back on the 4th)
It's ok, you don't need to "assure" me.
Again, I've got friends with children widespread over the country and all are back on the 8th/9th.
I've never known Christmas holidays to only be a week, they've always been two weeks, right from when I was at school.
DS school used to break up up the week before Christmas and go back the 2nd but the City council have changed it to break up on the 22nd, back on the 8th/9th.
5 other city council's that I know of have also done this.
So it was surprising to learn it wasn't standard across the board and that some schools only have a week break.
I'm guessing they get extra holiday somewhere to make up the days off through the school year. We get 7 week summer holidays as the school does a week's worth of teacher training at the beginning.
