The Dark Triad is a construct which includes three conceptually distinct, but empirically overlapping variables – Machiavellianism, subclinical psychopathy and narcissism. They exist within normal functioning and allow us to understand the adverse side of human personality. All three traits are connected by manipulation and deception of others. Employees who are high on a particular trait tend to use different impression management tactics to create their image within the organization (Jonason, Slomski and Partyka, 2012). The aim of this study was to contribute to the understanding of the relationship between the use of impression management tactics, personal reputation and the Dark Triad traits in organizational context. Research was conducted on a heterogeneous sample of people employed in the public and private sector (N = 250). We used Dirty Dozen scale (Jonason and Webster, 2010), Impression management scale (Bolino and Turnley, 1999) and Reputation scale (Hochwarter, Ferris, Zinko, Arnell and James, 2007). The latter was redrafted for colleague assessment. Research results showed that those who score high on Machiavellianism and narcissism use all five types of impression management tactics, while those who score high on subclinical psychopathy most commonly use the tactics of intimidation and supplication. Contrary to expectations, the correlations between Machiavellianism, psychopathy and reputation in the organization did not prove to be statistically significant, while correlation with narcissism was significant, but negative. In addition, the correlation between the use of certain tactics and reputation did not prove to be statistically significant.
