Job hierarchy refers to the structured arrangement of positions within an organization, illustrating the levels of authority and responsibility. Typically, it starts with entry-level positions at the bottom and progresses to higher management roles at the top. This structure helps define reporting relationships and ensures that tasks are delegated appropriately. In a job hierarchy, each level has specific roles and expectations. For example, supervisors oversee employees, while managers supervise supervisors. This clear organization allows for efficient decision-making and communication, ensuring that everyone understands their place within the company and its goals.
