An employee overpayment occurs when the employee receives compensation which (1) should not have been issued or (2) is greater than that to which the employee is entitled. This includes but is not limited to overpayment of wages, annual and/or sick leave paid in error, as well as, erroneous refunds of deductions. Unearned payments to employees are prohibited by Sections 66 and 96, Mississippi Constitution of 1890, which prohibits donations of public funds and extra compensation to employees.
