The survey classifies three types of employees among the 100 million people in America who hold full-time jobs. The first is actively engaged, which represents about 30 million workers. The second type of worker is "not engaged," which accounts for 50 million. These employees are going through the motions at work.

The third type, labeled "actively disengaged," hates going to work. These workers -- about 20 million -- undermine their companies with their attitude, according to the report.
