Workplace incivility is a challenging global occupational risk that is frequently considered trivial by managers and organizations. Often, complaints from targets are ignored; when this occurs, complaints can quickly escalate into formal grievances that cost businesses millions of dollars. While existing studies have uncovered cultural and gendered differences in how targets and organizations respond to workplace incivility, few cross-cultural studies have empirically examined how targets and organizations react to formal complaints. This study responds to this gap by using selective incivility, the transactional stress model, and national/cultural theories to conduct a multifaceted analysis of the underlying mechanisms responsible for targets’ organizational outcomes. Specifically, we tested a moderated model with 303 Australian (152 males and 151 females) and 304 Singaporean (154 males and 150 females) employees working in multinational organizations to determine whether the degree to which organizations took incivility complaints seriously moderated the organizational outcomes of work withdrawal and work satisfaction. Overall, the results indicated that, compared to Singaporean employees and Australian female employees, Australian male employees were less tolerant of being mistreated and continued to experience heightened job dissatisfaction and withdrawal even when their complaints were taken seriously by their organization. These results suggest that complex gendered and cultural differences influence the impact of incivility complaints on work-related outcomes.
