Bystander responses to bullying at work: the role of mode, type and relationship to target CoyneIain GopaulAlana-Marie CampbellMarilyn PankaszAlexandra GarlandRobyn CousinsFrances 2016 The current paper examines bystanders’ intervention intention to workplace negative acts across three studies based on international employee samples (N=766). Using a vignettebased design, we examined the role of bullying mode (offline vs. online), bullying type (personal vs. work-related), organisational action (presence/absence of bullying policy) and target closeness (friend vs. work colleague) on bystanders’ behavioural intentions to respond, to sympathise with the victim (defender role), to reinforce the perpetrator (prosecutor role) and to be ambivalent (commuter role). Results illustrated a pattern of the influence of mode and type on bystander intentions. Bystanders were least likely to support the victim and more likely to agree with perpetrator actions for cyberbullying and work-related acts. Tentatively, support emerged for the effect of target closeness on bystander intentions. Although effect sizes were small, when the target was a friend, bystanders tended to be more likely to act and defend the victim and less likely to reinforce the perpetrator. No significant main effects or interactions emerged for organisational action of providing a bullying policy. Implications for research and the potential for bystander education are discussed.
