This study aimed to examine the expression of these traits in work environments in Chile and Spain, taking into account potential differences based on geographic-cultural background, age group, occupation, and gender.Method: A non-experimental cross-sectional design was employed with a sample of 173 employed individuals. The Dark Triad of Personality at Work (TOP) questionnaire was administered, assessing egocentric views of work (EGO), imposing attitudes (IMPO), and impulsive/disengaged styles (NCI).Results: Male participants scored significantly higher across the three theoretical dimensions and in the subscales of Authority Need and Impulsivity (η2 = 0.026–0.054), although all scores remained within normative ranges. Chilean participants stood out in Leadership Attribution and Risk-Seeking (η2 ≈ 0.03); older adults (64–80 years) exhibited greater feelings of superiority compared to middle-aged adults (42–52 years); and managerial positions were associated with moderate-to-high scores in Leadership Attribution (T ≈ 56; η2 = 0.090). No significant differences were found in the global factors based on country, age, or profession.Conclusion: Overall, variables such as gender, geographic background, and organizational hierarchy appear to modulate adaptive expressions of dark personality traits, without reaching dysfunctional levels.
