In the critical review of the book “Ethics of management” written by Tomas Klikavar (2010), the present article has paid attention to the general approach of the author, the conceptual tools used, and the way of reasoning. According to the author, management, especially business management, due to the importance it attaches to the survival of the organization, has placed its fundamental principle on increasing benefit and earning profit, therefore, morality is not its fundamental issue, and it can even commit immorality in some cases, according to the necessity of tendencies and dispositions . As a theoretician of management ethics, from a historical point of view, the author has tried to show that business management has always been associated with unethical experiences, an experience that has continued until the present day as a kind of modern slavery. He believes that management ethics as an inter-discipline, which is considered a branch of management knowledge in terms of its subject, must be more intertwined with philosophy in practice. Finally, although the author has been able to show the inherent contradiction of management, especially business management, with ethics and provide a solution based on this, the fact that the author has succeeded in presenting a different theory in the field of “management ethics” is a matter of doubt and reflection.
