Which type of power would likely be most effective for a leader who lacks formal authority but possesses strong interpersonal connections?

Referent power is particularly effective for a leader who lacks formal authority but possesses strong interpersonal connections because it is derived from the personal qualities and relationships a leader has with others. Individuals are drawn to leaders who are charismatic, trustworthy, and relatable, leading to a natural influence over their peers and subordinates. This type of power enables those who possess it to inspire and motivate others based on mutual respect and admiration, rather than through formal position or coercion.

In contrast, coercive power relies on force or fear to influence others, which may alienate people and damage relationships, making it less effective for someone who is already strong in interpersonal connections. Legitimate power stems from a recognized position within an organization and does not apply in this case, as the leader in question lacks formal authority. Expert power, although beneficial, stems from specialized knowledge or skills that might not be leveraged as effectively without the foundation of strong relationships that referent power provides.
