Human Behavior in The Work Environment a Managerial Perspective by G. James Francis, Gene Milbourne, Jr. The behavioral approach assumes that people can contribute more to an organization than just the performance of a specific task . It also assume that people will in turn receive more from the work experience than just the pay . While these assumptions may seem very logical to today's managers and students of management, the evolution of this type of thinking is fairly recent. Chapter one will present a brief account of some of the major contributions in the development of the foundations of a behavioral approach to work . Why people work and the nature of the work role will be explored in order to provide insight into the reasoning behind the two assumptions stated at the beginning of this introduction. The discussion will then be directed towards how a behavioral approach actually influences organizational effectiveness.
