The attrition rate is a measure used to indicate the percentage of employees who leave a company over a specific period. It helps organizations understand workforce stability and can highlight issues such as job satisfaction or management effectiveness. A high attrition rate may suggest problems within the workplace, while a low rate often indicates a healthy work environment. To calculate the attrition rate, divide the number of employees who left during a given time frame by the average number of employees during that same period, then multiply by 100. This metric is crucial for human resources and management teams to assess and improve employee retention strategies.
