What reflects how much employees feel that the organization values their contributions?

The correct answer is Perceived organizational support, as it directly reflects employees' beliefs about how much the organization values their contributions. This concept refers to the extent to which employees believe their organization appreciates their efforts and cares about their well-being. When employees perceive that their organization supports them, it can lead to increased job satisfaction, commitment, and engagement. This perception often influences their motivation and overall performance.

In contrast, factors like job satisfaction encompass a broader range of aspects, including work environment, relationships with colleagues, and job roles, rather than focusing solely on the perceived value of contributions. The diversity of the workforce, while important for various reasons, does not specifically address how employees feel valued. Withdrawal behavior, on the other hand, typically refers to actions taken by employees when they feel disengaged or undervalued, but it is a consequence of poor perceived support, rather than a direct measure of how valued employees feel.
