Reservists received their first affirmative statutory protection as part of an amendment to the Military Selective Service Act in 1968 often referred to as the Veterans' Reemployment Rights Act ("VRRA"). The VRRA protects reservists against reemployment discrimination caused by their military duty. The Veterans' Readjustment Assistance Act of 1974 re-codified provisions of VRRA but included similar provisions protecting reservists from employment discrimination with an emphasis on inducing individuals separating from active military service to serve in the reserve components of the post-Vietnam all volunteer military.
