Blow off some steam, come in and rant
Observe your boss for a few days and try to notice how many things she does well versus poorly. When she is doing something “bad,” try to imagine the most forgiving reason why it could have occurred. Is it truly her fault, or could it be something out of her control?No matter how bad your boss' behavior, avoid letting it affect your work. You want to stay on good terms with other leaders in the company (and keep your job!).
