i live in Pennsylvania and work for the largest finance company in the industry. i have been off work the last three months on an approved disability leave. i purchased disability insurance through my employer and have been being paid by it. my supervisor is very unhappy with my taking this time off and is trying to terminate my employment since i am over the 12 week family medical leave act time limit. can he legally terminate my employement while i am under an approved medical leave? and if he does, what are my legal rights?
