has my job changed too much?

[imwaiting]

When I started my job (20+ yrs ago) I had to deliver 30 sessions to schools over a 34 week period. The other 4 weeks was taken up with admin/meetings type stuff. I delivered to individual pupils, or groups of 4 kids.
20 years on, I have to deliver 35 sessions over 38 weeks. I have to deliver to whole classes at primary schools.

I have been on the same pay point since I started, because I do not have a particular qualification, so cannot go any higher.

AIBU to be fed up? Or is it just natural business development/progression?

There’s no enough information to tell us whether your experience should be enough to move you up the pay scale. Some jobs, 20 years experience makes you very different to a new starter, other jobs I’ve seen it expressed as 20x 1 year experience.
So the pay might be fair.

30 sessions increased to 35 - whether that’s reasonable entirely depends on your contract.

If you’re bored of it now, move on?

On the individual and small group vs large group… again, there’s not enough detail. Do you need more skills for the large group, or just different? I don’t think that necessarily represents a big enough change to warrant a different pay band. If they’re paying for you skills and large group delivery is harder / more specialist then it might attract more money. But if they’re paying for you time, then it doesn’t matter how many in your audience.

OK.
I'm trying not to out myself. But I'll go for it.
I work for a County council music service.
Teachers who have a PGCE get paid more than teachers who have come in from being pro musicians/music college teaching diploma.
So being asked to do whole class teaching seems to me to be quite different from teaching 1-4 children at a time.
My original contract does not state the amount of sessions to be delivered across the year.

It’s different, but it’s not necessarily more skilled. I’m not a music teacher - but I’d have thought you do a bit more crowd control with a larger class, but probably a lower level of teaching, as they don’t progress as fast. I don’t see a reason that either should be paid more. If you were used to teaching a large class and it changed to 4, and they said, “we’ll pay you less as there are less kids” you’d say, “hey, I’m still teaching for an hour, no matter how many there are!” Works both ways.

The sessions thing is odd that it was never specified. Are you paid per session though?

Not paid per session.
im just annoyed I now work for a month longer. My working hours do not seem to have decreased so it’s not spread out over the extra weeks.
