I am on a CS part time, part year contract. I asked to change to compressed hours. So I do the same number of hours, same number of part year weeks but over fewer days. I didn't realise that this would cause an issue with my pay to do this change mid year (my part year is usually reviewed in March and the change happened in August.)
They said that I have effectively ended my part year agreement so I have to pay back this money over three payments. They gave me no notice of this. I just checked my online banking and saw I had been paid 150 quid less than usual.
I raised a query about this and had a call from someone who said I would not get this money back. And because I hadn't queried it before the first payment they would be taking the full amount in three instalments, just in time for Christmas. I said how could I query it when I wasn't notified and she couldn't answer this one.
So my part time salary is still a set amount per year but I won't actually be paid that amount this year.
It seems that they have now found a load more unconnected overpayments in my salary going back to 2017 and have sent me a schedule which basically shows a random amount with basic pay arrears next to it. They will now be taking this money back too. No explanation of how this occurred.
My union rep said payroll won't speak to them due to confidentiality.
Something similar happened to a man at work and he fought it but I don't know what to say to them. I don't understand their explanation when I speak to them.
