“…Although researchers have developed an understanding of the individual and situational factors that predict whether individuals will engage in workplace deviance (e.g., Barling, Dupré, & Kelloway, 2009) as well as the associated consequences (e.g., Aquino & Thau, 2009), comparatively less attention has been devoted to investigating third parties' reactions to the deviant behavior of others. However, given that the majority of incidents of workplace mistreatment occur in the presence of others (Glomb, 2002), understanding third-party reactions to such deviant acts is particularly important, as the reactions of these individuals can have significant implications for the perpetrator as well as the victim (Bowes-Sperry & O'Leary-Kelly, 2005). For example, third parties could provide advice and social support to the victim, or even decide to intervene to stop the perpetrator (O'Reilly & Aquino, 2011).…”
