In which decade did the human relations approach gain significant popularity?

The human relations approach gained significant popularity during the 1920s, primarily as a reaction to the limitations of classical management theories that focused solely on task efficiency without considering the human element in the workplace. Key studies, such as the Hawthorne Studies conducted during this time, highlighted the importance of social relationships, employee satisfaction, and the psychological aspects of work. Researchers observed that employees' productivity was influenced not just by physical conditions but also by social factors such as teamwork, communication, and emotional well-being.

This paradigm shift laid the groundwork for modern management practices that prioritize employee engagement and organizational culture. The human relations approach emphasized that fostering good relationships among workers and between employees and management could lead to enhanced productivity and job satisfaction. The findings of this era have continued to influence organizational behavior theories and practices well into the present, making the 1920s a pivotal decade for the development of management thought centered around human interactions and the importance of the workforce.
