In 2005, the Union filed two grievances on Singleton’s behalf challenging the Respondent’s decision not to select him for the Hearing Office Director (HOD)[1] position in the San Antonio office. (Jt. Ex. 2 at 2, 4). The case went to arbitration. On March 12, 2008, Arbitrator John B. Barnard, issued a decision stating that the Respondent failed to properly consider Singleton for the position based on his whistleblowing activities and awarded him priority consideration for any future HOD vacancy. (Jt. Ex. 2 at 8). On September 29, 2010, the Authority denied the Union’s exceptions. See AFGE, Local 3506, 65 FLRA 121 (2010) (Local 3506).
