Respect probably comes pretty close to the top of the list.
We like to work for a supervisor who thinks we are somebody and takes pains to treat us that way. We are all pretty independent creatures and do not really like having supervisors. It often hurts our pride to have anyone in a position of authority over us. We submit to authority not because we like it but because we choose to. If a supervisor shows respect for us and treats us as important individuals, it goes a long way toward easing this natural resentment and makes our jobs more pleasant and satisfying.
