ANSWER: Yes. Even if you are fired from your government job (except for treason or for certain other select offenses), you are eligible for disability retirement. In fact, it is not unusual for employees to be fired just because their disability precluded them from coming to work on time or from performing satisfactorily on the job. In those cases, the adverse action itself may enhance your ability to win disability retirement. But such employees, as everyone else, are required to file for disability retirement with OPM within one year of being separated from the government.
