What term is used to describe the number or percentage of employees that leave and need to be replaced?

The term that describes the number or percentage of employees that leave and need to be replaced is employee turnover. This metric is crucial in human resources and management because it reflects the organization's ability to keep its workforce stable. A high turnover rate can indicate underlying issues, such as poor job satisfaction, lack of career growth opportunities, or ineffective management practices. Understanding turnover helps organizations implement strategies to enhance employee satisfaction and retention, which can lead to more consistent service quality and reduced training costs for new hires.

Employee retention refers to strategies and practices designed to keep employees in an organization, while attrition typically refers to a gradual reduction in the workforce occurring naturally without direct replacement. The term "employee hiring rate" focuses on how quickly new hires are integrated into the workforce rather than the dynamics of employee departure.
