Mayo is known as the founder of the Human Relations Movement, and was known for his research including the Hawthorne Studies and his book The Human Problems of an Industrialized Civilization (1933). The research he conducted under the Hawthorne Studies of the 1930s showed the importance of groups in affecting the behavior of individuals at work. Mayo's employees, Roethlisberger and Dickson, conducted the practical experiments. This enabled him to make certain deductions about how managers should behave. He carried out a number of investigations to look at ways of improving productivity, for example changing lighting conditions in the workplace. What he found however was that work satisfaction depended to a large extent on the informal social pattern of the work group. Where norms of cooperation and higher output were established because of a feeling of importance, physical conditions or financial incentives had little motivational value. People will form work groups and this can be used by management to benefit the organization.
He concluded that people's work performance is dependent on both social issues and job content. He suggested a tension between workers' 'logic of sentiment' and managers' 'logic of cost and efficiency' which could lead to conflict within organizations. The behavioral management theory is often called the human relations movement because it addresses the human dimension of work. Behavioral theorists believed that a better understanding of human behavior at work, such as motivation, conflict, expectations, and group dynamics, improved productivity.
