To permit public school teachers and other staff who retire and begin collecting a pension to return to work in a school district and claim both a paycheck and a pension check if at least 12 months have passed since the "retirement." Under current law, with some exceptions for hard-to-fill positions, public school retirees who "double dip" get reduced benefits. The bill would also repeal a requirement that a school district must contribute toward paying-down the unfunded state pension liabilities associated with employing a retired teacher.
