Douglas McGregor's 1960 book is a vital study of the conditions that make employment satisfying and meaningful. Traditionally, managers assumed people were lazy and would not work unless strictly controlled. McGregor believed this was a faulty view of human nature. He proposed that managers draw on research in psychology and other social sciences to create working conditions that allow all employees to realize their potential, using principles that attempt to satisfy human needs. Declining to back one theory over another because workers have very different motivations, McGregor nonetheless argues that when people find work satisfying, they work more productively and efficiently.
