This course examines the role of ethics in leading organizations. In particular, it focuses on ways in which business and organizational activity may promote common good by applying virtue ethics. The course begins with a discussion on leading theories in business ethics and it pays special attention to the presentation of neo-Aristotelian virtue ethics with its personalist foundations. Then we frame ethical issues in business and organizations with theoretical concepts and case studies in a broad range of contexts, including: moral judgement in decision-making process, purpose-led business, use of power in the organization, virtuous leadership, meaningful work within organizational behaviour, institutionalizing ethics, and corporate social responsibility.
