The role that personality plays in the justification of organizational sabotage behavior was examined. In a two phase study, 120 business students were first surveyed to create a list of 51 methods of sabotage. In the second phase, 274 other business students rated justifiability of the 51 methods and completed Machiavellian and hostility scales. A factor analysis of the justification ratings yielded four factors: (1) methods of sabotaging company profits and production, (2) informational sabotage, (3) violent and illegal methods, and (4) traditional labor methods of sabotage. A 2 (high versus low Machiavellianism) ×2 (high versus low hostility) ANOVA upon factor scores for justifiability revealed significant main effects for hostility and significant interactive effects on Factors 1 and 2. Results were discussed in terms of differences in management and blue collar methods of sabotage and in terms of a self-presentational approach to justification of sabotage.
