Douglas McGregor proposed that managers use one of two different assumptions concerning people. His theory is called the Theory X and Theory Y view of managers, which reflects these two different sets of assumptions.
The Theory X view is the negative set of assumptions. The Theory X manager believes that people are lazy and must be forced to work because it does not come naturally to them.
The Theory Y holds that people will look for responsibility and that work comes naturally to people. This is seen as the positive assumption about people.
Generally, Theory Y manager will have more motivated employees. Sometimes, the Theory X manager can achieve results when used in the appropriate situations. But today’s workforce, as a rule, seeks more challenging jobs and an opportunity to participate in the decision-making process. This is closer to the assumptions of the Theory Y manager.
