Final answer:
Managers plan and organize to achieve goals, while leaders inspire and support individuals to realize visions. The director of a summer camp for chronically ill children is an example of an expressive leader who focuses on emotional well-being.
Step-by-step explanation:
The difference between a leader and a manager can be seen in their core functions and approaches. While managers focus on planning and organizing to achieve goals, leaders are more about inspiring and motivating people to realize a collective vision. Expressive leaders, in particular, are associated with promoting emotional strength and health, ensuring that people feel supported. An example of an expressive leader could be the director of a summer camp for chronically ill children, as this role typically involves emotional support and fostering a positive environment.
On the other hand, instrumental leaders are primarily concerned with task accomplishment and often hold positions such as army generals or CEOs. Leadership styles such as democratic, laissez-faire, and authoritarian affect how leaders and managers interact with their teams and influence the organization's culture and efficiency.
