Literature review of employee work engagement and recommendations for best practices for employers. Only one in every five workers is highly engaged in their work. Increased employee engagement in work results in better employee productivity and loyalty. Companies with high employee engagement outperform low engagement companies in many areas of business success. Engagement can be improved by using more positive supervisory communication styles, offering workplace mental health services to employees, and by larger organizational-level changes. The experiences of AAA of Northern California, Nevada and Utah, Molson Coors, and Pitney Bowes provide relevant employer case examples.
