In the Federal Civil Service, we have this little Catch-22. If you file for Disability Retirement from the government, you have to prove you’ve filed for Social Security Disability Insurance (SSDI) before your retirement request can be approved by the Office of Personnel Management (OPM). However, SSDI tends to cast a jaundiced eye on filings made by people who are still (technically) working.
But soft! We have a FORM for that. We call it the FEDMER. “Federal Medical Evidence of Record”.
Ya fills it out after you go through the tedious online process of filing for SSDI. Then you send it back to your HR office… and wait. This proves that “I have filled for Social Security disability benefits, but I have not received a decision. I will provide my Human Resource office with proof (e.g., copy of Social Security disability application receipt…)”
