Just had an email from my boss saying HR/payroll think they have been overpaying me.
I have a permanent contract & did some o/t on monthly contracts for a few months. Every month it had to be renewed and I had a new contract for the o/t hours( so I'd have 2 contracts). This finished last spring and off hand I can't remember when but approx march when I was first pg. Over spring/summer payroll/HR managed to pay me^ incorrectly regularly regarding my pay grade increase, my promotion & sick pay so all my payslips have deductions/add ons and none being straight forward.
During this time myself/ union hada lot of conversations with both departments on the phone & by email and eventually it was put right by the time I went on mat leave. I also received a schedule of payments for my maternity pay.
Fast forward to today when someone queried with my manager how many hours im working & they think they've overpaid me( paying both sets of hours together until now -somehow mixed into my mat pay)
I am pretty sure originally both sets of pay were separate on my payslip but can't check as they are boxed up in the loft & can't climb the ladder due to my SPD. I have payslips from April onwards & rough calculations do make it look like I've been over paid.
So do I have any rights over this considering they should have stopped when the contract did, noticed in the many discussions over my pay/mat pay? Or will they just say I should have noticed? Do I have to pay back straight away or longer? I'm the only wage earner at the moment & can't afford to lose much!
TIA :)
