Trade secret theft is a problem that almost all organizations face. The greatest threat is employee mobility and potential unethical post-employment behavior. This study investigates the role of individual personality traits in judgments about trade secret misappropriation. Our hypotheses were tested in three studies addressing three different situational contexts: current employees, employees about to be laid off, and students who had quit their job. Relationships were estimated with robust regression. The results show that some personality traits predict judgment about another (...) person's trade secret misappropriation, and that the situational context in which individuals formulate their ethical judgment moderates the impact of personality traits on ethical judgment.
