Employees will eventually be notified about how much they have been overpaid, Dunn said, and will be given two options to pay the city back: They can have it all taken out at once from their next paychecks, or they can let the city deduct an agreed-upon amount from their paychecks until their tabs are settled. The deductions must be at least $100 per check, he said. The city will ensure the overpayments do not inflate retiring workers’ pension payments, which are based in part on their final years’ salaries.
