Which of the following correctly describes the Unity of Command principle?

The Unity of Command principle emphasizes that each employee within an organization should report to only one direct supervisor. This structure helps maintain clear lines of authority and responsibility, which simplifies decision-making and accountability. When a subordinate has a single supervisor, it reduces the potential for conflicts and confusion regarding instructions or objectives because the chain of command is straightforward and unambiguous. This clarity is essential for effective communication, efficient workflows, and cohesive team dynamics.

The other options do not align with the Unity of Command principle. Having multiple subordinates report to one supervisor does not violate the principle, but it doesn't clarify the relationship between subordinates and supervisors. A situation where a subordinate reports to multiple supervisors potentially leads to conflicting objectives and confusion, which directly contradicts the essence of Unity of Command. Lastly, a supervisor with no subordinates does not apply to the concept, as there is no direct report to manage.
