Getting to know your boss well is very important, and it can help you on the day-to-day as well as to get promoted. In addition to having a solid relationship, you should know what his or her’s likes and dislikes are, values, and expectations. Knowing those things can be useful in performing tasks, and the general understanding of how the boss’ mind works can set you apart from the other employees. Often times knowing what you should be aware of is a good thing too, because you don’t want to be on his or her’s bad side.
