As a Supervisor how much more money would you expect to be on?

[Sycamorespoon]

I’ve recently been promoted in my team and I now have visibility of my teams salary.

I accepted an increase of my salary from 36k to 39k on taking the promotion but can see that the other senior member of the team that I now manage is on 38k! Rest of the team are on various salaries from 28k - 31k.

Im a bit pee’d off to find that I’m only on 1k more than someone I now manage and want to go in at the next pay review and argue that I should have a considerable raise - with the next pay rise my colleague will be on almost the same salary as me otherwise.

I have an awful lot more responsibility and now manage 6 people - surely there should be a few more thousand between me and the highest team member?

Whats the point in me having this extra responsibility for hardly anything! I may as well step back!

That’s not unusual. Could be any manner of reasons - TUPE contracts, length of service, could be at the top of their band and you’re starting at the bottom of yours.
Your salary could have been re-evaluated/lowered and span a larger band?
This is common in the NHS and other sectors where specialist knowledge attracts a higher salary. And people still need to be line managed.
Find out your band and salary progression but don’t go in all guns blazing in a new job. That won’t be a good look.
