I think it's wrong. He's been working with her for 10.5 years, and he's only firing her because his wife caught him for what he had been doing. If his wife hadn't caught him, he wouldn't have fired her.
Its even worse that other men in a judicial standing said he could fire her for nothing she did wrong at all. It's pathetic.
Maybe he should learn to love his wife, and stop fooling around. Firing someone because you can't control your own urges. What a sick and pathetic excuse of a man. I hope his life gets turned upside down. I hope people that went to him before decide to find someone with better character.
