Final answer:
Line managers report to middle managers and supervise nonmanagerial workers, often exercising an authoritarian leadership style. Expressive leaders, such as the director of a summer camp for chronically ill children, focus on the group's morale and social stability.
Step-by-step explanation:
The individuals who report to middle managers and supervise nonmanagerial workers are known as line managers. Line managers are in direct control of the core business and have authority over the work of nonmanagerial employees. They typically carry out functions related to the basic objectives of the organization such as production and sales, thus their communication pattern is often top-down, reflecting a more authoritarian leadership style as opposed to democratic or laissez-faire styles.
On the other hand, an expressive leader is more likely to focus on maintaining the group's social stability and morale. Among the options provided, the director of a summer camp for chronically ill children is more likely to be an expressive leader, because their role would include nurturing and attending to the well-being of the children which is critical to the success of the camp.
