Abstract

Bystanders Moral identity Moral psychology Workplace discrimination Business Administration
Workplace discrimination remains a persistent organizational challenge, yet few studies have examined the factors that influence bystander employees' willingness to speak up when such behavior occurs. This study examines how characteristics of discriminatory incidents and personal characteristics shape bystander intervention in workplace settings. In a quantitative, experimental vignette study, participants were exposed to video-based scenarios that manipulated the offender's hegemonic status (hegemonic vs. non-hegemonic), the type of discrimination (racism vs. sexism), and the overtness of discrimination (overt vs. covert). Willingness to speak up (WSU) was operationalized as a composite of willingness to intervene and willingness to report. Participants' moral identity was also assessed to explore potential moderating effects. Data were collected from 627 participants through MTurk and analyzed using hierarchical regression and moderation analyses. Results indicate that lived experience with discrimination initially predicts WSU; however, these effects become non-significant after accounting for moral identity. Moral identity emerged as the strongest predictor of WSU, suggesting that internalized moral values are central to intervention behavior. The offender's hegemonic status consistently did not predict WSU, whereas the participant's hegemonic status consistently showed a negative relationship with WSU, indicating that hegemonic employees are less likely to intervene. Contrary to expectations, the type of discrimination (racism vs. sexism) and organizational context variables (e.g., workplace climate, DEI stance) were not significant predictors. Furthermore, moderation analyses revealed that moral identity does not uniformly strengthen intervention behavior; rather, it operates as a conditional regulator. Specifically, a significant three-way interaction between hegemonic status, discrimination overtness, and moral identity suggests that the influence of situational factors depends on both hegemonic identity and moral identity. At lower levels of moral identity, individuals were more responsive to situational clarity, whereas at higher levels, intervention behavior was more consistent across conditions. These findings contribute to the literature by demonstrating that willingness to speak up is driven more by internal identity-based factors than by external organizational or situational cues. The study underscores the importance of moral identity in shaping ethical behavior and suggests that organizational efforts to promote intervention should consider employees' moral self-identity alongside efforts to address structural power dynamics.
