For a friend who's a teacher, this is not about the pay so much as EVERYTHING.
For example, pensions. My friend started teaching in 1989, aged 22. She is now 47. From the age of 22 a sizeable chunk of her salary has been taken ("superannuation") to fund her pension.
During her career so far, she has been informed she will not be retiring at 60 as she thought in 1989, but at 68, i.e. 8 years longer paying in to her pension, 8 years less taking her pension out. Despite this, she has been told that the sizeable chunk of her salary that has been taken for the last 25 years has not been enough to fund the pension that she thought she'd be getting in 13 years' time, and that she will need to increase payments for the next 20 years in order to get what was originally promised.
All this while on a pay freeze which has no end in sight, at a time when pressure is being increased on teachers from all sides, not least the witless Gove. [Have you seen the pensions that MPs get, by the way?]
So my friend did strike yesterday. She wasn't paid, but she went in to school anyway to help put final details in place for a trip that she's taking the kids on today and over this weekend, which she's giving up also unpaid. This included, for example, collecting epi-pens for students who may suffer from anaphylactic shock while in her care.
My friend, who is a very good, caring and effective teacher, is looking at leaving education. Here's another reason why. She teaches at the top end of a secondary school, ages 15-18. She is being asked to "add value" to students who come into the school on inflated grades that they have been given by primary schools years before, primary schools that themselves were manipulating the system to achieve their own targets. You can't "add value" to a student that has been wrongly measured - you especially cannot "add value" to an A* student. There is only one way to go once such a student is properly measured by external examination. The whole system is cracked and the teachers that care most suffer most.
Some teachers are really crap, but good teachers deserve a lot better than they're getting at present. Many of the bad teachers are staying in education, and many of the good teachers are leaving. Those that care about giving good education should be taking a stand to stop some of the appalling steps that are causing this.
