Let me know if you have two ways communication between you and your boss. This happened to a friend of my that told me that he has a new Boss in the company. He treated them badly and kept scolding the employee.
There is lack of two ways communication where one did not tell why and what happened. We cannot reach each other mind. I know nobody like to have the guessing game. If you are working in a company I am sure you do not want to see any trouble. I think everyone will want to have a secured job.
