Employee turnover data measure the rate at which employees leave an organization and are replaced by new hires. Knowing employee turnover is key for businesses to maintain a healthy workforce and operational efficiency, as it provides an indication of job dissatisfaction, potential unfairness, loss of productive workers and an inability to attract top talent. By studying turnover data as part of an overall strategy for retaining and rewarding employees, organizations can ensure that their workplace culture is conducive to productivity, growth, and success.
