One of the main reasons why people are motivated to do a job well is the sense of <em>achievement</em> they get from it. Achievement is the feeling of pride that comes from knowing you have done your job well.
A second type of motivation that is common in the workplace is that of <em>power</em>. Some people get a lot of pleasure out of having power and authority. This is not necessarily a bad thing, as sometimes these people are particularly good at directing others and can make good managers.
Both types of motivation are common, and they can be very important in the workplace. However, the sense of achievement can be created by the person individually, and requires little group work. On the other hand, the motivation of power depends on the type of interaction the person has with others.
