Before Douglas McGregor's seminal work on management, employees were often presumed to be lazy and unmotivated. As a result, conventional wisdom held, management must goad workers into becoming productive cogs in the machine. McGregor revolutionized human resources thinking by positing two ways managers could view employees: Theory X assumes workers are inherently lazy; Theory Y assumes they are self-motivated. While not clearly on the side of Theory Y, McGregor seems to lean toward the idea that management should ultimately set the workplace conditions to allow people to not only do well at work, but to want to do well.
