Current frameworks on ethical decision-making process have some limitations. This paper argues that the consideration of moral competencies, understood as moral virtues in the workplace, can enhance our understanding of why moral character contributes to ethical decision-making. After discussing the universal nature of four moral competencies (prudence, justice, fortitude and temperance), we analyse their influence on the various stages of the ethical decision-making process. We conclude by considering the managerial implications of our findings and proposing further research.
