Employee turnover is a measure of how many people leave a business or organization, expressed as a rate or a percentage. It’s a metric used to gauge the health of an organization’s workforce and its ability to retain employees over time. Employee turnover can have both positive and negative effects on a company. High turnover can lead to decreased morale, lower productivity, and higher costs for recruitment and onboarding new employees. Low turnover, meanwhile, suggests job satisfaction, loyalty and stability. In either case, measuring turnover regularly helps organizations identify trends and take steps to improve their retention rates.
