I am a Federal executive branch civilian employee (and I do not work for the Federal Bureau of Investigation or the Intelligence Community)
Retaliation involving most personnel actions, such as termination, demotion, suspension, or reassignment: You may have the option of submitting a retaliation complaint with the U.S. Office of Special Counsel (OSC). OSC is an independent federal investigative and prosecutorial agency. OSC protects federal employees and applicants from prohibited personnel practices, including whistleblower retaliation. Some OIGs may also accept and investigate agency employee whistleblower retaliation but it varies across OIGs.
Retaliation involving a security clearance or access to classified information: OSC has primary jurisdiction over retaliation complaints by Federal executive branch civilian employees. However, OSC does not have jurisdiction in cases involving an alleged retaliatory revocation or suspension of a security clearance or access to classified information. If you believe you have been subjected to a retaliatory security clearance action, you may contact the OIG for your agency.
