When the workplace betrays you...

Okay, let's say you had a friend who came to you for advice about his workplace. Here is a brief scenario:

There is a powerful man who has a great deal of influence at work. This is because he is in charge of a lot of money. But TheBully shits on most of his colleagues, who for some reason just accept this as his "personal style."

Your friend was not hired by TheBully, but by another person who directly supervises him. He simply borrows space in the TheBully's factory because the supervisor has a different kind of factory. And so, there are weekly meetings with his direct supervisor and TheBully.

In these meetings, however, TheBully verbally beats up on your friend.
Meeting One: TheBully, calls your friend, "Not passionate enough."
Meeting Two: TheBully claims, your friend is not working hard enough or fast enough, that TheBully will have to find someone else to replace your friend.
Meeting Three: TheBully tells your friend that he has two strikes against him. That he is not meeting expectations.

Now you know this friend quite well and you know that he works really hard. You know, for example, that your friend spend a month of unpaid work to learn the job from a previous factory worker who was leaving. That he didn't take a Christmas holiday so that he could replace the raw materials in a production line. Finally, in the course of literally one year, your friend has managed to get enough raw materials to produce two finished goods. By way of comparison, the person previously employed by TheBully for six years produced raw materials of very poor quality and thus no finished goods. Not only that, TheBully's factory has not produced any goods of high quality in the last 5 years. Needless to say, your friend's real supervisor has been quite happy with your friend's job performance so really it isn't a question of productivity.

Finally, Meeting Four: TheBully shouts questions at your friend about the raw materials. Remaining calm, your friend tries to answer the questions. But this was a 'question and answer game', where your friend answered, "Yes" and the bully would say "Wrong, it's no." Similarly if your friend said, "No" the bully yells, "Wrong, it's yes." After angrily spitting false accusations at your friend about stealing company materials, TheBully screams at your friend calling him arrogant. Several times, the supervisor tried to intervene but TheBully shut him down too. Then, TheBully stormed out of the room several times, and when he finally came back, asked your friend to get his raw materials out of his factory. Furthermore, TheBully ended the relationship not just with your friend but with his supervisor, saying he didn't care what the hell they did.

The next day, worried about some of the raw materials still in production in the TheBully's factory, the supervisor approaches TheBully. He tries to ask him what to do about the raw materials and to address the angry words in the previous meeting.

TheBully denies ever asking your friend to get his raw materials out of his factory. He denies it all.

What advice would you give your friend about this workplace situation?
