A month or so ago I got a letter from my previous employer asking for nearly £400 which they say they overpaid me when I left. They’ve now sent a second letter demanding the money, along with an updated wage slip which talks about holidays and redundancy pay that I can’t make head nor tail of. Am I obliged to pay this money back?
Probably, but a wages department that makes errors in your favour is equally likely to make further errors in favour of the company. Discuss the pay slip with the wages department, and, if you’re satisfied that an overpayment really was made when you left, offer to repay the money at so much a month.
