Employee Retention Model is the process of forecasting, measuring, and managing employee turnover in an organization. It helps organizations understand why employees leave and the everyday management practices that reduce turnover. By understanding the patterns and trends of employee turnover, it becomes easier to plan and implement cost-effective strategies to improve long-term staff retention and performance. The model involves steps such as tracking employee attrition, analyzing causes for employee exits, predicting when employees may leave, and developing policies to keep them engaged.
