I have worked for several bosses. The best one ensured that he knew what your rights were, and that you received them. He was fair and treated us without bias or favour. He was approachable and protected us from outside criticism. If he felt you had done something wrong he would tell you in private, and in such a way that you felt you had been advised by a wise elder - not chewed out. As a result we felt valued and were loyal.
Sadly my current boss is almost the exact opposite.

 I like to be treated fairly and given credit where credit is due, I expect feedback regarding my performance. If I need to imptove, I expect guidance to steer me in the right direction. I also want to know what is expected of me and what I can expect of my manager.

Strong leadership is certainly a plus, but my work ethic demands that I do the best I can in any situation. A good manager may motivate me to work harder, but I would never do less than I am capable of doing.

 Definitely would want a list of expectations from my boss. A boss that can has good leadership qualities and can motivate employees is critical because it takes different methods to motivate all types of people. A boss that is strict but knows when to show compassion is another trait I would look for in a supervisor. And, a boss that earns the respect of his/her employees is so important. I've worked for many bosses but the one I the remember most is the one that said "I'm wrong" and wasn't afraid to admit it. He earned all of our respect!

 A boss who will interact with his staff and invite comment on improving the business. As a staff nurse, i have had good ideas that have improved patient care from all levels of staff from the cleaning staff to the medical staff and of course the most important element, the patients themselves. If the staff are made to feel a connection with the manager it will improve any service.

 Be nice to them, understanding, caring and look after them. Make sure they have nice facilities and remember they are human too!

 The boss who encourages his employees, motivate me. Where the boss motivates his employees the organization will prosper more.

Regarding the second question I would do a good job

 I would rather have a boss that tells me what to do in high detail but lets me do most the work myself without any advice.
