Workplaces are becoming increasingly international. In many contemporary workplaces, English is used as a lingua franca (ELF). This chapter introduces the notion of WELF, Workplace English as a Lingua Franca, which is used as a means of conceptualizing English that is used in international workplace settings. The chapter focuses on the language skills and strategies that are deployed by successful WELF users. An important aim in conceptualizing WELF is to help English learners to find their own answers to the questions of why they need to learn English, and what it means to be a competent user of the language. A further aim is to reach out to English teachers working in contexts where students can be expected to work in globalized workplaces.
