What term describes the loss of employees by a business for various reasons?

The correct term for the loss of employees by a business for various reasons is "staff turnover." This concept refers to the rate at which employees leave an organization and are replaced by new hires. High staff turnover can indicate issues within the workplace, such as poor employee satisfaction, lack of advancement opportunities, or inadequate compensation.

In contrast, employee retention focuses on the strategies and practices that organizations implement to keep their current employees engaged and reduce turnover. Recruitment pertains to the processes of attracting, selecting, and appointing new candidates to fulfill job vacancies. Workforce reduction often refers to the deliberate downsizing of employees, which is usually done for financial reasons or to improve efficiency, rather than the general concept of employees leaving an organization for various reasons.
