Final answer:
The person least likely to be talked to by Jamie about her bad day at McDonald's would be her supervisor due to the professional dynamic involved. In terms of expressive leadership, the director of a summer camp for chronically ill children would likely embody the qualities of such a leader.
Step-by-step explanation:
Among the given options, the person least likely to be talked to about a bad day at work for Jamie, who works at McDonald's, would be b) Supervisor. While coworkers, parents, and friends might provide a sympathetic ear and support as part of a social network, a supervisor might not be seen as a confidant due to their position of authority and the potential professional consequences of sharing personal grievances.
In regards to the question about expressive leadership, c) The director of a summer camp for chronically ill children is more likely to be an expressive leader. An expressive leader focuses on group harmony and morale rather than strict goal or task orientation. Working with chronically ill children would require a great deal of emotional intelligence, empathy, and attention to the well-being of the group, which are hallmarks of an expressive leader.
