Workplace bullying is a recently recognized problem within organizations. Two personalities may be theoretically related, and may be able to predict this aggressive behavior: right-wing authoritarianism and social dominance orientation. However, it is still unclear how to measure right-wing authoritarianism as a construct. Two surveys were distributed. The first was to assess the factor structure inconsistency among the literature. A three-factor operationalization was supported. Analysis of the second survey examined the relationship between the aggression dimension of right-wing authoritarianism, dangerous worldview and workplace bullying; as well as the relationship between social dominance orientation and competitive worldview on workplace bullying. No significant relationship was found between authoritarian aggression and workplace bullying, however, social dominance orientation fully mediated competitive worldview and workplace bullying. Theoretical implications, limitations, and practical applications are discussed.
