A experiência de Hawthorne || Elton Mayo || Teoria das Relações Humanas

Summary

The Hawthorne Experiments, conducted by Elton Mayo in the late 1920s and early 1930s, revealed the powerful impact of social and psychological factors on worker productivity. The study showed that informal groups, social relationships, and psychological well-being significantly influenced performance, rather than just environmental or physical conditions. Key findings emphasized the importance of group dynamics, leadership, and work environment in boosting efficiency. This led to the development of human relations theory, which stresses the value of human interaction and psychological factors in organizations for improving both employee satisfaction and organizational success.
