Who mediates OSC complaints?

OSC has an ADR Unit with three full-time mediators who devote the bulk of their time to PPP and USERRA mediations. OSC maintains a roster of internal mediators, trained in mediation and federal personnel law, to serve as neutral and unbiased co-mediators. Additionally, OSC occasionally co-mediates with training mediators from outside the agency (such as volunteer mediators and Federal Mediation and Conciliation Service mediators).
