Abstract:
Interpersonal injustice and job complexity as predictors of workplace aggression were investigated among a sample of 320 employees drawn from two campuses of university of Nigeria, Nsukka. Workplace aggression was assessed with 33 items that made up the three types of workplace aggression by Baron, Neuman and Gedders (1999) while interpersonal injustice was measured with 4 items drawn from Organizational Justice Scale developed by Colquitt (2001) that assess the domain of interpersonal injustice. Job complexity was assessed with 5 item scale developed by Frees, Kring, Soose and Zempel (1996). Pilot studies were conducted using Nigeria samples to validate the instruments. Result of regression analysis showed that interpersonal injustice positively significantly predicted workplace aggression (=.12,P<.05). The result also showed that job complexity positively significantly predicted workplace aggression (=.13, P<.05). The findings and implications were discussed based on the theoretical and empirical background and on the Nigeria socio-economic realities. Limitations of the study were stated and suggestions made for further research.
