I left teaching two years ago to move abroad, and I would have been M6 (top of the main scale). I've just checked and my salary if I'd stayed would have been £29k+ now I think, so not anywhere near the £34,000 quoted. To achieve that, one has either to take on extra responsibility or apply to get through threshold, which is a lot of extra paperwork and proving what value you have added to the school.
The average teacher does NOT earn £34,000 outside London at all.
If we were paid for just teaching, then it would be OK, but is the associated crap that goes with it all; sorting out quarrels, being a social worker, chasing up parents and students, not being able to make a flip comment in the supermarket to a student without the fecking parent complaining the next day, paying to feed some of the students because they don't have lunch with them, people not turning up for appointments when you've stayed in school until 1800 to see them and it's not parents' evening, dealing with stoned kids period 5 every Friday, which disrupts the lesson, teaching 600+ kids a week and having all the reports for these students packed into a term along with behaviour, effort and attainment grades. I could go on....
Yes, I had long holidays, which I used to catch up with marking and planning for next term, although I did have some weeks where I didn't work. I used to work on average 60 hours a week in term time. Realistically, if you are marking a set of 32 books, and you give each book 3 minutes to ensure that all the errors are corrected, and comments are written, you are looking at 90 minutes per set of books. I tried to mark two sets a night, as I taught about 17 different classes. There is planning on top of that, which takes time, especially for AS level. I also did 4 unpaid after school sessions per week to teach GCSE and run a revision course.
I think that people don't realise that a schemes of work and lesson plans are not done. We have to look at what the NC prescribes, and then produce the SoWs, lesson plans and resources from that. These also have to be regularly rewritten to keep up with any changes and studies that have been done into methods of learning etc. New methods of teaching come in, so you have to adapt to those and ensure that everyone is teaching in the same way.
Oh, and some of us have our own kids as well!
As for having one of the best pension schemes...that would be the scheme to which all the MPs belong wouldn't it? We contribute to our pension scheme at 6% of our salary, so it is not like a civil service pension. However, it is hopefully a secure pension, but that was always the payback for working in the public sector, that the pension would be good.
