Temkin Group research shows that engaged employees are valuable assets. They try harder at work, are less likely to look for a new job, and feel more committed to helping the company succeed. We found that companies with stronger employee engagement competencies are more likely to use social tools as part of their internal efforts than other companies. For best results, companies should introduce these social capabilities into their employee engagement plans to enhance what we call the “Five I’s of Employee Engagement”: Inform, Inspire, Instruct, Involve, and Incent. We interviewed 17 companies for this report, including EMC, Fidelity Investments, Houlihan’s, Humana, Oracle, SunTrust Bank, TELUS, and USAA, and identified more than 20 best practices enabled by social tools. We also added a checklist to help organizations introduce social tools to employees.
