Taking a unique personalist approach and placing human action at the heart of conducting business morally and ethically, this textbook makes the case that a successful business is an ethical business. Domènec Melé, who has over 30 years' experience in researching, teaching and consulting in business ethics, argues that businesses are simply the sum of their people. This textbook emphasises the promotion of human excellence and the development of humanistic businesses where people remain central to the organization. This edition addresses contemporary challenges in business ethics shaped by technological advancements, societal evolution and global economic shifts, including artificial intelligence, environmental ethics, sustainability and corporate social responsibility. The book includes coverage of international standards proposed by recognised authorities, including the UN and the International Labour Organization, as well as global case studies and reflective questions in each chapter. Students can dive into the complex decisions made by some of the world's most powerful multinationals. The use of well-known examples, including Enron, Volkswagen and Siemens, provides a 'jumping off' point for students new to the study of philosophy and ethics. Business Ethics in Action is the ideal companion for undergraduate, postgraduate and MBA students of Business Ethics worldwide.
