The purpose of this research was to study the moderating effects of personality characteristics on the relationship between perceived organizational justice' dimensions and work place violence tendency. The research method was descriptive-correlational and statistical population consisted of all male employees of a big automotive industry (4638 persons), from among which 269 employees were selected via simple random sampling. In this research a set of questionnaires consisting of work place violence tendency (Mehdad, Tabkh eshghi & Mehdizadegan 2011), perceived organizational justice (Niehoff & Moorman, 1993) and NEO-FFI Big five fctor Personality Inventory (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 (b=-0.05, P>0.05), and verbal (b=-0.09, P>0.05) violence tendency and neuroticism moderated the relationship between perceived distributive justice with physical (b=-0.09, P<0.05) and verbal (b=-0.14, P<0.01) violence tendency. 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 which may be considered in the employees selection process.
