Supervisors play a key role in employee retention through ensuring job satisfaction across compensation, opportunities, recognition, and work environment (CORE) elements. While turnover is often viewed as an HR issue, research shows an employee's relationship with their supervisor most impacts retention, as supervisors control CORE factors. To improve retention, organizations need performance management systems that reward supervisors for reducing turnover. Supervisors must understand the steps they can take to fulfill their responsibility in boosting employee job satisfaction and retention.
