I worked for the NHS in a band 6 role for 5 years before I got a job at band 7 with another Trust. I joined the bank so I could do the odd band 6 shift with my old Trust and at the time they put me at mid point band 6, one spine point lower than I had been on my full time salary. I challenged this at the time but was told that this was due to not having a caseload and having universal contacts only rather than anything more complex. We backed and forth for a while before they put me on the same spine point I had been as a permanent team member.
Honestly, from there, I didn't give it anymore thought and I never checked my payslip really as I never did more than one shift a month at most and it was always just a bit of extra pocket money rather than an essential part of our income. This was 5 years ago and I have had 2 maternity leaves since then when I didn't work on bank at all for 2 non-consecutive years.
I have just returned from maternity leave now and started doing a bank shift once a week on top of my normal job to earn some extra money as mat leave swallowed all our savings. For the first time, I looked at my payslip and saw I'm still at midpoint band 6 when I should have been top band 6 for at least 3 years. I emailed my manager to ask why this was and she immediately came back and said of course I should be at the top of band 6 and adjusted it straight away. But she's come back to say that I will be backpaid since returning from mat leave which is only one month ago.
Truthfully, I'm not that fussed, I haven't worked much the past 3 years (1 day a month roughly then a full year of nothing until last month) and I was more gearing up to argue that I should be top band 6 expecting them to have had a reason for deliberately keeping me at mid point so the fact that they've agreed to move me straight away feels good enough. But I've mentioned it to DH and he says I should challenge again and say I expect it to be backdated for the full 3 years because that's where I should have been all along. But should I just let it go and accept that it's partially my fault for not looking at my payslips?
