The purpose of this article is to compare the results of our own research on the competence structure of managers of Polish companies as perceived through the prism of issues related to management ethics, and trust management in particular. From the perspective of our own research work on modeling the competency profile of executives of Polish companies, the results of three empirical studies have been presented and compared. The research on the competency profiles of managers in Polish companies was of different nature. The first and third competency profiles were created based on an empirical study of a single workplace. At the same time, the first profile was statistically representative of that enterprise, while in the case of the third profile, the research was exhaustive. In the case of the second competency profile, the research was statistically representative of a specific type of managerial personnel, as in this case it was an entrepreneur-manager, who cannot be identified with the typical so- called contract manager. In the author's opinion, this is why the research work described has significant cognitive value from the perspective of ethical aspects of management, and trust management in particular. In conclusion, it can be said that the level of management ethics in Polish companies is quite low, while the need for its improvement is mostly indicated by those who are, as it were, its recipients. After all, the people most responsible for creating ethical behavior in the organization are primarily managers. These, in turn, as can be seen from the described research, in most cases do not see such a need.
