Redefine terms under the School Employees Retirement Act and the Class V School Employees Retirement Act

This bill (LB 689) clarifies rules for school employees in Nebraska's retirement systems when they temporarily return to work after separation. It redefines when a return to work as a temporary, substitute, or volunteer employee counts as a "termination" for retirement benefits, and specifies when employees can restart retirement contributions and accrue service credit. The bill also updates procedures for members who withdraw retirement contributions (taking a refund) and later return to work, allowing them to restore refunded amounts under specific conditions. These changes directly affect current and former school employees participating in Nebraska's School Employees Retirement Act or Class V Retirement Act.
