Last year I requested a reduction in my hours from full time (37.5 hrs) to 32 hrs. I did this through formal channels with my manager and have the paperwork to back up my request. I have never looked at my payslips (all electronic, don't get them through the post), and just took for granted that this had been correctly processed as requested, and therefore assumed that the new amount I was being paid reflected the number of hours I'd asked for.
I have looked at my payslip for the first time properly today and noticed it says 33 hours at the top. I've looked back and they are all the same, since I requested the reduction. This means for the best part of a year I have been paid for 1 hour more per week than I've worked.
I am now really worried that if I raise this with my manager I will owe back a lot of money. 😩 Can to be made to pay it back if I raise it, do you think? This obviously wasn't my error as I was very clear in my flexible working request that I wanted to reduce to 32 hours. But could they argue that I should have checked my pay slips before now? What should I do?!
