I also paid out an employee who went on maternity leave. Her last day was different, but she decided to leave a week early. I figured it out while doing JE’s. I went to my manager and told him about my mistake. We had two options – to pull back the payroll or to contact the employees and ask to pay it back. We choose the second option. The employee gave us the cheque. It was easy but I felt really bad. I was not able to forget this mistake for a couple of months.
