Payroll are generally ****e. There it is. They overpaid me last year, I called FIVE times to sort it. About 4 weeks ago I get a note from our admin lady asking why I have never passed on the overpayment forms. BECAUSE I NEVER HAD THEM! Payroll said I had! I know several people who have been overpaid and never been chased after initial contact. So they worry that if they leave they will get zero. Also know several people who have been underpaid, missing shift pay, overtime, over taxed after recieving proper tax code. I work in ground services, so at least I know payroll aren't just being personal.
