Which management principle stipulates that each firefighter should report to only one supervisor?

Unity of Command is a fundamental management principle that emphasizes the importance of having each firefighter report to only one supervisor. This principle is vital for maintaining clear lines of authority and responsibility within an organization, especially in high-pressure environments like firefighting. When each firefighter knows exactly who their supervisor is, it reduces confusion and helps ensure that orders and communications are consistent and clear.

This principle aids in establishing a structured chain of command, which is critical in emergencies when swift decision-making and adherence to directed actions can have life-saving implications. The unity of command helps to avoid conflicting directions from multiple supervisors, allowing for a more cohesive and effective response to incidents.
