Research on both private- and public- sector organizations has found that increased levels of engagement— generally defined as the sense of purpose and commitment employees feel toward their employer and its mission—can lead to better organizational performance. GAO was asked to review recent trends in federal employee engagement and steps OPM and agencies are taking to improve it. Among other things, this report: (1) describes trends in employee engagement from 2006 through 2014, (2) identifies practices in improving employee engagement, and (3) evaluates OPM’s tools and resources to support employee engagement. To meet these objectives, GAO analyzed responses to FEVS questions from 2006 through 2014, conducted a regression analysis, and reviewed OPM documents and interviewed OPM and other agency officials.
