When it comes to judgemental conclusion of people's acts, I've always been careful and maintain a total calmness because I never can really tell what influences such acts. The so called boss I'm working for, obviously has anger issues and I find it very difficult to tell what triggers such irritating habit. Unfortunately, it is uncontrollable by him. He releases it whenever it comes. I've tried as much as possible to avoid falling into the pit of false consensus bias - i.e, the tendency of assuming other people should think like me. I work my ass 50 - 60+ hours a week + weekends for his startup company without expecting much in return but he still feel people are not important to him. Nothing actually interests me anymore in the company and I feel quitting is a necessity for me right now - please, I need people's opinions regarding this.
