"I think if you work hard and are recognised as being good at your job then that opens up the prospect of promotion."
Not every good teacher can be promoted, especially in a small school, and promotion isn't necessarily the best thing for everyone anyway. Lots of people get promoted because they are good at job x, but then promotion removes them from that and puts them into job y.
"As it is teachers' pay isn't just one flat rate. There are scales dependent on things like experience."
But that's the whole point really isn't it? To get away from automatically being paid more if you sit there longer, the concept where you have adequate teachers who have been teaching for ages but are nothing special but get paid loads more than teachers who may not have been doing it as long but do an exception job, going above and beyond etc etc
I'm withholding judgement myself on the new system, but I do have an aversion to any form of salary structure which rewards someone for sitting there for longer than someone else.
In the same way that I would advise someone recruiting for a post not to seek x years experience in the ad, but to seek x type of experience, because someone could have 15 years experience of doing a mediocre job, whereas someone could have 3 years experience of doing a fantastic job.
I don't know how well the new system for teachers will work, so I am withholding judgement as I say. I do understand that teachers and others have concerns about it and why. I am going to have involvement in it in our school and it will be interesting to see how it works.
