Final answer:
Worker productivity and motivation are improved through positive work experiences according to the Human Relations theory, which emphasizes psychological and social aspects and contrasts with the Scientific Management theory.
Step-by-step explanation:
The theory suggesting that worker productivity and motivation can be improved through positive work-related experiences is the Human Relations theory. This theory contrasts with the Scientific Management theory, which focuses on labor productivity and efficiency through mechanistic restructuring of work processes. On the other hand, Human Relations emphasizes the psychological and social aspects of the workplace, proposing that employees are more productive when they are motivated, satisfied, and valued, which can be achieved through better interpersonal relations, involvement in decision-making, and supportive supervisory practices.
Douglas McGregor's Theory X and Theory Y illustrate two opposing perceptions of worker motivation and management style within the broader Human Relations approach. Theory X aligns with traditional management practices that view employees as inherently lazy and needing strict control, while Theory Y aligns with the Human Relations school of thought, suggesting workers are self-motivated and seek fulfillment in their work. Theory Y promotes a participative, inclusive, and flexible management style that empowers employees and encourages their contribution to organizational success.
