Final answer:
Managers are the individuals who guide and oversee the work of other employees within an organization. They hold a key position in the organizational hierarchy, directing subordinates and implementing company strategy.
Step-by-step explanation:
As part of the orientation for her internship, Rebecca was informed that managers are the people who direct the activities of others in an organization. Managers play a key role in the hierarchy of authority within companies, being responsible for both the execution of organizational strategy and the oversight of subordinates. While traditional organizational structures have emphasized a clear chain of command, there has been a notable shift towards flatter structures that promote teamwork and more evenly distribute responsibilities. In this context, managers are still distinct from line workers, who are typically non-managerial employees directly involved in the organization's primary operations, and from directors, who may hold higher executive-level positions or board appointments, depending on the specific organizational chart of the company.
