Employee turnover is the rate at which employees leave an organization and are replaced by new hires. It’s a key metric for assessing the health of an organization, as it affects employee morale, customer service, and overall productivity. High turnover means more costs related to hiring and training new employees, while low turnover signals long-term stability and organizational harmony. Measuring employee turnover can also provide insights into important factors like leadership effectiveness, workplace culture, job satisfaction, and salary competitiveness, allowing employers to take proactive steps to create an environment that attracts and retains top talent.
