I work in a school, part-time and I love it. I have no bargaining power as I'm really not going to leave whatever the response is.
I've been there 3 years and am over qualified for the job, but that's OK, I needed to step back from what I was doing before. The school know I'm over-qualified/have experience which could earn me a much higher salary and I was grilled on this at the interview.
However, in the last 3 years they have taken advantage of my skills and I'm now doing more senior work than they employed me to do. The job I'm doing now is not the one in the job description iyswim. Similar jobs are advertised at other schools at least 1, sometimes 2 grades higher.
Is it likely that my job should be re-graded, or is it my "fault" that I've taken on the extra work? I'm not especially worried about the money (I wouldn't be there if I was!) but I don't like to think I'm letting them take advantage of me. I'm also thinking a bit about my next job and that if I was a grade higher on paper, a job more akin to what I was doing before wouldn't be such a leap. It has to be said though that working at a higher level suits me too - makes my day more interesting.
Naturally, the school budget is tight and anyone who asks for more (hours or pay) is generally met with contempt. What do you think, is it worth asking if the grade is right?
