Abstract: The spiral effect model between uncivilized behavior in the workplace and workplace ostracism can be explained by moral exclusion theory and emotional event theory. According to the theory of moral exclusion, suffering from workplace incivility will lead to the increase of psychological distance between the victim and the perpetrator, which will lead to the workplace ostracism of the perpetrator; From the perspective of bystanders, witnessing workplace incivility will affect the moral sense of justice and interactional justice of the bystanders, which in turn will lead to workplace ostracism of the perpetrator. In addition, the above mediating effect will be moderated by the level of altruism. Based on the emotional events theory, suffering from workplace ostracism will affect the emotional level of the victims of workplace ostracism and will push them to be the perpetrators of workplace incivility.

Key words: workplace incivility, workplace ostracism, spiral effect, moral exclusion, emotional events
