Correct Answer:
B. Social factors and employee morale
The Hawthorne studies, conducted at the Western Electric Company in the 1920s and 30s, were groundbreaking experiments initially designed to investigate the impact of physical working conditions, like lighting, on employee productivity.
The correct answer, Social factors and employee morale, highlights the studies' most significant discovery. Researchers found that psychological and social factors, such as group dynamics, informal relationships, and the feeling of being valued and paid attention to (the 'Hawthorne effect'), had a far greater impact on productivity and morale than the physical environment or financial incentives alone.
- Lighting conditions only was the initial focus, but the studies revealed that lighting itself was not the primary driver of productivity changes.
- Strict supervision was not a key finding; instead, the studies suggested that a more participative and supportive approach, where employees felt observed and cared for, was more effective.
- Financial incentives only was also disproven; while incentives play a role, the studies showed that social and psychological factors were equally, if not more, influential.
