What important quality should have a perfect boss? This is a very deep question. Did you notice sometimes how employees hate their boss. I thinks it happens because the boss has lack of certain characteristics and professional traits. I will try to describe some of them that are very important in my opinion. The perfect boss should be skillful, fair and ambitious.
First of all, employees or colleagues have to feel that their boss is more skilled than they are. This is a very important for successful work. For instance, if I know that my boss knows more than me in a certain area, I will trust him. A good boss has to have more experience , and more knowledge than I. Only in that case will I respect him or her.
Second important quality for a good boss is fairness. People are very sensitive about certain things. For example, my collegee and I have equal qualifications and the same experience, but my colleague has a higher salary because the boss somehow loves her more. It is unfair. This situation will cause a bad atmosphere or hostile work environment in the office. It will effect the efficiency of work that will be done.
Finally, I believe that a good boss should be ambitious. This quality is really necessary, because the more ambitious the boss is, the more successful he or she will be. Obviously, people who have a lack of ambition never become big bosses. This trait allows him or her to go further and further towards his or her dream. I think a good boss dreams about a successful business; good, friendly and efficient crew; and achieving his goals.
In conclusion, I can say that a good boss should have a lot of particular qualities, but the most important are – business skills, fairness and being ambitious.

Note: I would reword it a bit as I have just included my copy.
