The effects of descriptive and injunctive social norms on workplace incivility

Abstract This research examines workplace incivility through the lens of the focus theory of normative conduct, demonstrating effects of descriptive and injunctive norms on incivility perpetration. Using an experimental vignette methodology, Study 1 demonstrated that incivility intentions toward an insulting colleague were higher when organizational incivility (vs. civility) was described as both common (descriptive norm) and approved (injunctive norm). Study 2 disentangled the influences of descriptive from injunctive norms, demonstrating that each exerts an independent effect on incivility intentions. In Study 3, workers' perceptions of the descriptive and injunctive norms for incivility at their organizations predicted their uncivil intentions toward an insulting colleague—beyond the effects of other established workplace mistreatment predictors. Study 4 replicated these findings in predicting uncivil behavior frequency; additionally, job satisfaction accentuated the effects of both norm types and organizational identification amplified the effects of injunctive norms. Overall, results support key tenets of the focus theory of normative conduct, provide novel evidence for individual difference moderators of the norms' effects, and suggest that norm‐based persuasive messaging interventions may hold promise for discouraging workplace incivility.
