Ok, so what in 61.53 are you reading that says it is illegal for an employer to ask for a note from a doctor in the event of a sick call?

I mean I understand the whole self certify thing, but it can really get out of hand. If for some reason I just don't feel like flying because I would rather be home watching Gilmore Girls, is that a valid sick call? Am I unfit to fly because I'm just "not feeling it?"
