Yeah, this guy is a jerk. I don't know him (don't want to) but I can tell by the way you describe him he's a piece of crap.

He does not respect you, and that is why he feel's the freedom to treat you like you're useless. He will belittle and demean you as much as he can because you stay and let him. This is sort of like being married to an abusive spouse. But he knows he can't hit you without getting sued so he does the next worst thing -- verbally abuse you as often as he can.

He obviously has a problem with subordinates and power or perhaps with male-female roles. (I am assuming you are female.) Most men who are verbally cruel and ugly only are that way with women, children and young people they hold power over. He would never dare act this ugly to a judge, a jury or a police officer because he is a coward. It is easier to attack employees.

If he fires you, he wins. If you quit, he wins. If you stay and let him tear you down, he wins. When he presses your buttons and you lose it, he wins. He gets a selfish, twisted, bizarre and sick pleasure when he is able to talk down to a person and that person must comply silently. He was probably spoken to this way when he was younger, and now he is unleashing it on others he knows he can put down.

You could quit and be rid of him forever. You could have your husband or boyfriend show up at the office occasionally (to escort you home or take you to lunch) to let him know there is a symbol of power and force in your life who probably would not tolerate this behavior if he knew of it. You can stay and endure this indefinitely until he fires you or lays you off or you lose it and go postal.

I do not see him changing and behaving in a better way toward you unless he undergoes some sort of radical change in his life (embracing religeon or experiencing a breakthrough in psychotherapeutic counseling).

The partner who knows and says nothing is cowed and submitted to him already, a lost cause. It obviously does not bother him that you (and others before you) have been mistreated. If it did, he would either put his foot down and demand his partner stop or else he would dissolve the partnership and "fire" this jerk. The fact that he stays and allows it to go on means he is an enabler, in agreement with it and is content to allow you (and those who will follow you) to suffer under this psycho.

He isn't worth working for. Neither one of them are. You shouldn't keep working for people you can't respect. The stress will make you sick. You will go from appreciating the fact that you have a job to feeling like you are on your way to prison when you get dressed in the morning.

If he would just show you what he needs and congratulate you when you do things right, he would show he is a good man who wants to bless others. But handling you and your errors the way he does shows he is a bad man (a sick man mentally) who wounds and injures others. He doesn't understand management, people, how society functions best or what a functional relationship is.

Unfortunately, I think the only things that may help him change are abandonment, continued rejection and extended failure over a number of years. You should take his critique to heart and use it to improve your performance.

BUT HE DOES NOT DESERVE YOU.

You can find another work and then quit if you like, but if it's hard I think it's better to stay until you find something else.
I have the same situation here and I can make you sure that it's really makes me feel sick, but for now I'm planning to speak with him frankly that I don't like this situation and if he insist to stay like that I will leave the job as soon as possible.

But you know, sometimes I feel that he needs help and respect, and I try to give him that, even sometime make some jocks with him, but other times I can't stop thinking of reply him the same way he treating me.

GOD be with us.
