For a certain portion of the federal retiree population, and some others from non-federal government, one of the most frustrating features of Social Security is what they don’t get. The Windfall Elimination Provision and the Government Pension Offset, WEP and GPO can be confusion for how they limit Social Security benefits for affected people. Federal News Network’s Drew Friedman and I got a tutorial in WEP and GPO from certified Social Security advisor for the Association of Mature American Citizens Foundation, Russ Gloor.
