Though TSA employees (including security screeners) may file complaints with OSC, the processing of complaints can differ between TSA non-screener employees and TSA screeners. TSA non-screener employees may file complaints alleging retaliation for protected whistleblowing under 5 U.S.C. § 2302(b)(8). OSC will process these complaints under its regular procedures, including filing petitions with the Merit Systems Protection Board, if warranted. TSA security screeners may file complaints alleging retaliation for protected whistleblowing under 5 U.S.C. § 2302(b)(8) pursuant to a Memorandum of Understanding (MOU) between OSC and TSA executed on May 28, 2002. The MOU and TSA Directive HRM Letter No. 1800-01 provide OSC with authority to investigate whistleblower retaliation complaints and recommend that TSA take corrective and/or disciplinary action when warranted. Additional information on OSC procedures for reviewing security screener whistleblower complaints under the MOU is available at http://www.osc.gov/tsa-info.htm.
