For clarity, given what's posted up thread, I just want to talk about take home pay for main scale teachers. Although we get a good pension, the contributions are 8.6% for most main scale teachers. On top of this, the vast majority of main scale teachers will have student loans.
For a teacher outside London on M6 with my student loans and my pension contributions, take home pay is £2144 a month. I am not suggesting that's not a comfortable salary, but in terms of strike day deductions, it works out at about £70 per day, not over £100 as previously suggested.
For a teacher on M1 (i.e. an ECT in most cases), take home pay is 1668. Around here, probably £700 of that is going in rent, but that's a separate issue.
I think this is the other issue when comparing salaries with other professions- in terms of, e.g., your ability to get a mortgage- M3/M4 is quite a bit lower in take home pay than it would be for people who don't have student loans and aren't paying an excessive amount into a pension.
I know the pension is good, but it's hard to feel that benefit at 25, and for those who stay in the profession less than 5 years, it is pretty much wasted money if you move to the private/third sector.
A lot of people who move out of teaching actually find they get a similar take home pay on a slightly lower salary, which is another point which needs to be made about starting salaries.
Also, for clarity, most NEU branches have set up hardship funds. If you've just joined the NEU and are worried about striking because of the financial cost, then please do speak to your local branch and they will explain how to apply. Most will cover the full deduction to your salary for each strike day, although it is usually retrospective, unfortunately.
