There is an ample body of knowledge showing significant association between five factor model (FFM) of personality traits and workplace bullying, yet exploring cause-and-effect relationship between them is still under addressed. To address this issue, current study has analyzed personality traits of Five-Factor Model as a potential antecedent of workplace bullying and its three sub-facets (verbal bullying, social bullying and physical bullying). Study analyzed responses of 266 respondents to draw inferences. Simple random sampling technique was used to collect data from the respondents. Correlation analysis showed a positive association of extraversion with physical bullying; negative association of agreeableness with workplace bullying, verbal bullying, social bullying and physical bullying; negative association of conscientiousness with workplace bullying, verbal bullying, social bullying and physical bullying; and negative association of emotional stability with physical bullying. Results of regression analysis showed significant effect of agreeableness, conscientiousness and openness to experiences on workplace bullying, verbal bullying, social bullying and physical bullying. Current study has identified personality as an important predictor of workplace bullying through which organizations may control incidence of bullying at their workplace environments. Current study also has highlighted important insights for future research directions.
