I filed my FMLA paperwork to my company for a "doctor certified" illness that falls within the FMLA and ADA guidelines, which placed me off of work and 5 days later, I received a notice in the mail that I was terminated. The company deemed me under FMLA after my 3rd day absent. Is this illegal to do? Also, with the termination letter, they offered me a severance /general release agreement for one months worth of salary. Is any of this illegal?
