<p>In this thesis it is argued, that managers with strategic responsibilities are unlikely to commit to contemporary business ethics, because its deontological nature is limited for strategic work's teleological focus. This is a problem because when managers do not commit to business ethics, they can damage the ethical culture in their companies. Unethical cultures are nests for scandals and malpractices that can hurt companies' reputation and, in turn, their profits. However, if managers were to commit to ethical behaviour the ethical culture would strengthen. For that reason, I have proposed an Aristotelian approach to ethics that could be useful for managers, when making strategic decisions. This could help strengthen the ethical culture in their companies. Three managers with knowledge and experience of strategic decision making have been interviewed to test the usefulness and ethicality of the Aristotelian approach. The findings indicate that the Aristotelian approach could be useful for guiding strategic decision making. One respondent even said that the Aristotelian approach's rhetorical considerations could improve strategic decision making in his company. Despite finding the Aristotelian approach beneficial for strategic decision making, two of the respondents did not think that the approach would be used for strategic decision making in their companies. The approach was said to be too abstract for managers to use in relation to all the practical issues they have to deal with. All the respondents agreed, that the Aristotelian approach highlighted some ethical considerations, but they were reluctant to call it an ethical approach. However, it did not really matter to them whether the approach was ethical or not, because to them, strategic decisions where ethically neutral. This final statement supports that the deontological nature of contemporary business ethics is not useful for strategic work.</p>
