why would he need ANY reason to fire her?? Was she under contract?? what's it the supreme courts business anyway. he is a private person, he can hire and fire who he wants for whatever reason he wants. he should be able to fire her if she is a woman as long as he is not breaking a contract with her.
if i hire a drug dealer for 10 years then all of a sudden i get the urge to do drugs, i should be able to fire him to distance myself from my new temptation
