In this episode, we examine how organizational justice and effective internal investigation systems sit at the core of the U.S. Department of Justice evaluation of corporate compliance programs. Drawing on benchmarking data from NAVEX Global and research from George Washington University, we explain why strong speak-up cultures generate more internal reports, detect misconduct earlier, and reduce enforcement risk. We also outline DOJ expectations for timely, independent, and consistent investigations, and provide practical guidance on building oversight, discipline frameworks, and monitoring systems that reinforce trust, fairness, and accountability across the organization.
