What type of power does Marc possess when he is seen as the most knowledgeable about his employees' jobs?

When Marc is recognized as the most knowledgeable about his employees' jobs, he embodies expert power. This type of power arises from possessing specialized knowledge or skills that others value and seek. In this scenario, Marc's expertise makes him a credible resource for his team, enhancing his ability to influence their work and decisions positively.

Expert power is particularly effective in a work environment because it fosters trust and respect. When employees recognize Marc's knowledge, they are more likely to rely on his insights, follow his guidance, and be motivated to achieve goals under his leadership. This dynamic can create a strong and productive team environment, as his expertise can lead to better performance and problem-solving.

In contrast, referent power typically stems from personal traits or relationships, coercive power is based on the ability to punish or control, and legitimate power derives from a position or title. While these forms of power may also play a role in a managerial context, it is Marc's specialized knowledge that defines his ability to influence and lead effectively in this situation.
