OSC Banner


​​​​​​​​​​​​​​​​​The U.S. Office of Special Counsel (OSC) is an independent federal investigative and prosecutorial agency. Our basic authorities come from four federal statutes: the Civil Service Reform Act, the Whistleblower Protection Act, the Hatch Act, and the Uniformed Services Employment & Reemployment Rights Act (USERRA).

OSC's primary mission is to safeguard the merit system by protecting federal employees and applicants from prohibited personnel practices, especially reprisal for whistleblowing. For a description of prohibited personnel practices (PPPs), click here.​​
