Can I seek Payment if I returned to work after 3 months of short term disability and was fired within a week of my return

After five years of service I was mugged in another city, after sustaining injuries I went on STD, apon my return I was fired for not being in the specific room were I work. I how ever was on the grounds but at a 2nd station where I would often visit to get supplies and materials I needed to get my job done. The officials used this excuse to take my position away. I believe I should be paid for a number of situation and for a number of reasons.
