Our school summer holidays are fairly long too, they are always under review but the possible move to a five or six term year with more regular short breaks seems to be on hold at the moment.
In English state schools they usually finish in late July and start again at the beginning of September. Scottish state schools finish at the end of June and start again in mid August, a period of around six or seven weeks. They usually get around two to three weeks at Christmas and Easter and up to a week off at each half term.
Some private (public) schools have very long holidays, as much as three months in the Summer and nearly a month at Christmas and Easter but they have school on Saturday mornings and only a long weekend for half term.
I feel a little guilty to hear about your lack of holidays. Most people that I know take at least five or six weeks a year, they don't always go away, sometimes they just have a break at home or with family. A few people that I know take four or five foreign holidays a year and hardly anyone I know takes less than one. How do we cope when we go back to work? You just expect to cover for people when they are away so that they will cover for you. In many offices, at any one time one or two people are away. I have never met anyone in the UK who has not taken a holiday in the last two years, they would be regarded as a little strange and probably be sent for counselling, funny how different our cultures are, isn't it?
Bye for now
