A term used in the context of “line and staff,” which refers to authority in an organization. Line authority is hierarchical: a floor nurse reports to a head nurse, who in turn reports to the chief of nursing, who in turn reports to the chief executive officer of the hospital who, finally, reports to the governing body. Only a person higher in this series is authorized to “give orders” to a person lower in the series.
