PurposeThe status quo for managing deviant workplace behavior is underperforming. The current research offers a new approach for scholars and managers in approaching these misbehaviors. Namely, we outline how system justification theory, which holds that people are motivated to rationalize and justify the systems—including workplaces—to which they belong even when those systems disadvantage them or others, offers value in explaining and addressing the prevalence of such misbehaviors and contemporary failures in managing them.Design/methodology/approachThis conceptual research explores the situated role of onlookers to patterns of workplace misbehavior, like harassment. We explore existing scholarship on why and how onlookers respond to such actions, including cultural elements, and draw parallels between those accounts and the foundational concepts of system justification theory to demonstrate an unrealized theoretical overlap valuable for its immediate applications in research.FindingsThe current paper establishes clear links between system justification theory and efforts to manage misbehavior, establishing system justifications as freezing forces in the culture of a workplace that must be unfrozen to successfully implement strategies for managing misbehavior. Further, we describe how organizational onlookers to misbehavior are subject to system justifications, which limit prescribed means of stopping these patterns of wrongdoing.Originality/valueVery limited organizational scholarship has utilized system justification theory, despite calls for such applications. Given the existing shortcomings in scholarship and management approaches to workplace misbehavior, the current research breaks from the status quo and offers an established theory as a new way to approach these misbehaviors.
