A friend of mine got fired because he was sick. He has a doctors excuse which stated he should stay home for 4 days. Said friend did sign an agreement with his employer that he should show up to work everyday. The reason for said agreement is said friend was missing a lot of days at work. My question is can his employer, federal government, fire my friend because he signed said agreement even though he had a doctors excuse to miss work for 4 days? Should he sue? What are his chances of winning? Any similar cases? TIA.
