Howard alleged that former District employee Dennis Ryan received District payroll checks after his employment with the District terminated. An overpayment can happen if there is an ineligibility notice, which disqualifies a claimant in certain cases where they have already received benefits.If the employee has already spent the money, it's possible the company and the employee can work out a repayment plan. IL law also does not require a final offer letter upon termination of employment, it simply requires final pay. If you don't, can they legally terminate your employment?
