I have been getting overpaid for a few months unknowingly and just recently my manager has informed me that I owe UPS $500 back in pay because of the payroll departments constant errors. I am a part time worker and only work 15 hours a week at most. If they were to take money from my checks then I wouldn't have enough to even pay for gas to make it to work for that week. Along with that I do not have a second job because I am focusing on my education. Had I known about my payment errors I would have said something to my supervisor, but I've never noticed it. Am I obligated to repay UPS because of the mistakes they have made? Or is there something the Union can do to help me out because I personally can't afford to be paid $20 for a few weeks. Please somebody help me out with this?
