Educating business students in language diversity is an orphan of management education. Few programmes devote an entire course or even a session to this topic in spite of its obvious relevance for companies in a globalised world. This chapter presents insights from a transformative teaching and learning experience of putting language diversity at centre stage. The one-week seminar delivered to an international group of MSc students at the London School of Economics contributed to transforming these students’ views of what it means to manage language diversity in business contexts. They reported a more holistic, critical, self-reflexive and resource-oriented view of multilingualism than at the start of the seminar. The chapter also offers a range of suggestions for educators teaching this topic.
