With the increased use of reserve and National Guard troops in full-time military service, employers must frequently deal with the requirements of the Uniformed Services Employment and Reemployment Rights Act (USERRA) of 1994 when those employees are called to active services and when they return. USERRA governs the leave and reinstatement requirements for military personnel. The law contains specific requirements for protected leave, rules for benefits employees are entitled to during military leave, and the requirements for reinstatement back in the civilian workforce.
