A Rural Letter Carrier petitioned for review of the initial decision that affirmed the Office of Personnel Management’s  decision denying her application for disability retirement. The Merit System Protection Board (MSPB) found that the employee established by a preponderance of the evidence that she was unable to perform useful and efficient service in her position.  MSPB determined that while the employee might have been able to perform less arduous duties, the applicable Collective Bargaining Agreement (CBA) prohibited consideration of rural carriers for light-duty assignments. Therefore, the MSPB ordered OPM to grant the application for disability retirement.
