The Office of Personnel Management (OPM)
The Office of Personnel Management – known by most by its acronym, “OPM” – is the Federal Agency which determines all Federal Disability Retirement applications, whether under FERS, CSRS or CSRS-Offset. All Postal and non-Postal Federal workers must ultimately submit their application for Federal Disability Retirement benefits under the purview, evaluation, and ultimate approval or denial from the Office of Personnel Management.
