This study extends incivility theory and research by applying multilevel theory and analysis to explain the effect of group-level incivility on intention to remain. Previous research has shown that experiencing workplace incivility is associated with adverse individual well-being and behaviour, such as turnover intentions, but the majority of research has been at the individual level of analysis. Consequently it is unknown whether incivility is also a group-level phenomenon, and what the effects of group-level incivility are on the individual. Results from over 34,000 employees working in 179 organizations across Australia and New Zealand showed that target reports of incivility could be aggregated to the level of the organization to form a shared stressor, incivility environment, which affected employees' intention to remain over and above their personal experience of incivility. This shared or environmental incivility also had a cross-level interaction effect on the negative relationship between individual incivility and intention to remain, highlighting the importance of context on targets of incivility. The role of interactional justice climate was also examined and the data are consistent with justice having a mediating effect on the cross-level relationship between environmental incivility and intention to remain. The findings are relevant to studies of bullying and harassment.
