I'm currently working part-time in a school I love. I got the job through a supply agency so I am still employed through them, but I've been asked if I would like to work full-time next year and be employed directly by the school. I immediately said yes to this and was then told the highest payscale I would be put on would be M4. I am wondering if anyone can tell me if this is OK? I don't want to be underpaid! My employment history is as follows: 2 years full-time (M1 to M2), followed by a year doing daily supply, and then this year working part-time. As next year will be my 5th year does that not mean I should be on M5? Or does it not work as simply as that?
