In this research a set of questionnaires consisting of work place violence intension (Mehdad &et al, 2011), organizational justice ( Niehoff & Moorman, 1993) and NEO-FFI (Costa & Mccrae, 1989). Data were analyzed with the use of moderated regression analysis. The results showed that extraversion moderated the relationship between perceived distributive justice and physical ( = β -0/05 ,P ), and verbal ( = β -0/09 ,P ) violence intension and neuroticism moderated the relationship between perceived distributive justice with physical( = β -0/09 ,P ) and verbal ( = β -0/14 ,P ) violence intension . But conscientiousness, agreeableness and openness to experience could not moderate the relationship between perceived organizational justice' dimensions and work place violence intension . Consequently, this study confirms that, extraversion and neuroticism moderated the relationship between perceived organizational justice and work place violence intension . Therefore, based on these results, it is recommended that organizations consider personality characteristics in selection process of employees. Manuscript profile
