What does the term 'labour turnover' refer to?

Labour turnover refers specifically to the rate at which workers leave a business within a certain period, typically expressed as a percentage. This measure provides insights into workplace dynamics, employee satisfaction, and the overall health of the organization. A high turnover rate can indicate issues such as poor job satisfaction, inadequate training, or insufficient compensation, while a lower turnover rate generally suggests a stable workforce and possibly effective management practices.

The other options, while related to workforce management, represent different concepts. The number of employee promotions focuses on advancement opportunities rather than departures. The average time workers stay in a company measures retention without capturing the active movement of employees out of the organization. The recruitment rate relates to the hiring process and doesn't directly address how many employees leave. Therefore, the first choice is the most accurate representation of what 'labour turnover' means.
