Theory Y : managers believe most people like work and naturally work toward goals to which they are committed . people are capable of using imagination and creativity to solve problems . Each worker is stimulated by rewards unique to that worker .

Theory Z : Management theory that focuses on trust and intimacy within the work group ,employees prefer to share responsibility and decision making , employees need guaranteed employment and will accept slow evaluations and promotions .

Management theories range from actively fraudulent, through completely useless to being somewhat helpful for some people.   However, part of the reason there are many is that you need different ones in different circumstances.   This makes them largely useless in practice.

Always remember the basic principle of good management - treat people as you would like to be treated.  This applies to everybody - your team, your boss, your colleagues and your customers.
