The importance of fostering employee engagement within the Federal Government has been widely recognized, and the “people and culture” portion of the President’s Management Agenda emphasizes the need to develop and sustain an engaged, innovative, and productive Federal workforce. To address this goal, the U.S. Office of Personnel Management (OPM) has made employee engagement a priority in OPM’s Strategic Plan. This report summarizes OPM’s review of recent employee engagement research regarding definitions, models, measurement practices, and interventions. It also presents a definition of employee engagement as it specifically relates to the Federal workforce and a model of engagement that provides a practical perspective to measuring and improving employee engagement. Finally, some recent best practices used to drive sustainable employee engagement are highlighted.
