Nearly half of all frontline leaders in U.S. federal agencies during 2015 were unprepared to improve employee engagement. The lack of successful strategies to improve employee engagement in federal government agencies has led to decreased operational performance. Guided by the employee engagement theory as the conceptual framework, the single case study design was selected to explore the successful strategies that frontline leaders use to improve employee engagement at a federal agency in central Maryland. Data collection involved face-to-face, semistructured interviews with 4 frontline leaders and federal agency documents indicating employee engagement. The data analysis process included Yin's 5-step method and revealed 2 major themes: effective organizational communication, and enhancing employee development. Employee engagement improves if frontline leaders use strategies that involve effective organizational communication and enhancing employee development to promote open, transparent communication, teamwork, collaboration, skills development, incentives, rewards, and improved work-life balance. The implications for social change include the potential to implement successful engagement strategies in the federal agency, because employees who are more engaged generate better performance and productivity, build valuable work relationships, enhance career, and increase wages to improve the well-being and prosperity of themselves and their families. Improved performance and productivity could help to lower operating cost at the federal agency; thus, creating opportunities to reinvest savings into local community outreach programs that contribute to healthy living, well-being, and economic prosperity.
