I have no axe to grind in the matter of the six week holidays in our schools as I am right at the very end of my teaching career and only do a handful of lessons weekly, so hope that my overview will come across as having nothing in it but a neutral assessment.What needs greater consideration however, I am strongly of the view that teaching is a profession with little to offer to a professional person. To earn a middling salary, the average teacher probably has to win some four promotions or more - each of which will probably add huge amounts to an already daunting workload.
To many - the long, summer break is all that keeps them in the profession. A very high number of young teachers will leave a year or two into a career when they understand what a shocking job it truly is. I shall not list those horrors today - but rest assured that the job is highly destructive in a good school.
In a bad one - well, I do not know where you will find experienced people ever to work in them. (And yes, I have experienced both.)
It is no surprise to me how many people are prepared to work for half basic salaries - or in one case I know, a 20% salary - to work in a Christian School because there is a peace of mind not possible in the state system. Money or sanity can be a real choice!
