Staff management is the management of subordinates in an organization. Often, large organizations have many of these functions performed by a specialist department, such as Personnel or Human Resources, but all line managers are still required to supervise and administer the activities, and ensure the well-being, of the staff that report to them. Staff managers include people who lead revenue consuming departments, for example, accounting, customer service, or human resources. They serve the line managers of the organization in an advisory or support capacity by providing them with information and advice. Furthermore, staff managers usually do not make operating decisions. Staff management may involve moving a workforce around and utilizing human resources. Within staff management there is also line management, which involves the hierarchy system of the organization. Human resources and line management are often aligned as they both involve employees of any given organization.
