I was working for a company for 2 months when I started getting an intense pain in my right side. I thought it may be my appendix so I called off work the next day to go to er. Tests showed it was a hernia and was told to not do anything for 7 days. I notified my employer immediately and told them I had a note from doctor. When my 7 days were up I notified employer about coming back to work and they told me I was terminated because of their "no show-no call" policy because they did not see my doctor's note. I did not file a workers comp claim and cannot receive help from anyone. Is there anything I can do? Is it illegal for them to fire me? Thank you for any input.
