There are a few of things to consider:
First, teachers have a pay freeze, will now be working longer, have to deal with the rise in living standards as well and will be paying more into a pension scheme that is frozen. And more importantly, more is being demanded from them in terms of their time - time I am sure the Public sectors would be paid for. (And no, I do not mean that teachers would not be giving their time, I'm just pointing out that time being demanded and time being given is different.) For teachers, that is a pay cut. More is going to be going out then coming in.
Secondly, teachers did not profit in the boom years. Our pensions were not plowed into a bank in another country to gain extra interest. It has not been subject to the stock market. So only a few short years ago, when the Private sector were enjoying inflated pensions tachers did not.
Thirdly, IT IS NOT JUST teachers who are striking. Teachers have the luxury to strike, and I think are doing so partly on behalf of those public workers who can not... nurses and the police.
Nope, teachers are not over paid. I love the figures banded about telling everybody how much teachers can expect to earn. If you are a specialist subject like science, you may join the profession at a higher pay band. If you work inner London, you will have London weighting. That does not mean that all teachers are earning this! But, we seem to be missing the obvious. It's not just what comes in, but what goes out. Everyone, including teachers have differnt calls on their finances. Yesterday I listened to the radio, where I was informed that teachers have two cars and shop in Waitrose. Good for them if they can afford it. I'm going to guess though that they do not have their own children and have paid off their mortgages.
There seems to be a feeling of, "if i can't have it anymore, they wont". Why? What makes you think that teachers are having it? Cooking, shopping, raising children are unversal costs, surely.
Oh, and why bother striking? Its an old fashioned thing, and I am a child brought up in the late 70s/80s, but is this not how we can have our say heard?
Martin Niemöller put it simply, "Then they came for me -- and there was no one left to speak for me". I have no intention never to speak.
