text: what is the criteria for disability retirement from the postal service? opm sorry that no one has answered your question yet...  i would suggest speaking with a manager/director over your branch.  do they know that you are having medical problems?  what are they?   there are a lot of different criteria for every company, much less the federal government.  this may be something that you may have to fight for, possibly even hire an attorney if need be.  i'm not sure as to the particulars of your situation, so i couldn't really tell you whether or not you should get disability retirement.  definitely go through the ranks until you get an answer...that's your best bet.
