My former direct superior has some mental issues and at some point he turned against me. On top of that, a native math teacher arrived at the school. I was teaching math. The agency downplayed my performance to prove to me I was not good enough wanting to give that new teacher my post. Then my superior wanted to move me to that new teacher post for less money breaching the contract. I refused and quit the job. The guy got angry since he had lost his face and here you go. The most ridiculous thing was the director didn't know about that and when I wanted to talk to him the Thai staff was making excuses so that I couldn't talk to him.
