Migration affects societies in different ways, including labour markets and specific workplaces. One of these effects is increased multilingualism. The study of multilingualism and work offers us a rich site for exploring the (re)production of social worlds. Moreover, work migration and multilingualism are of relevance to various agents and on different scales as:(1) a real-life concern to individuals, (2) a challenge and/or benefit to multilingual workplaces and (3) an ideological and often political stake in societies. Research addresses these perspectives from different approaches, e. g. language learning in the workplace, language use and practice in multilingual workplaces, language policy and, obviously, language ideology. Most of this research points to the negotiation of multilingualism as a
benefit or deficit, but also as an individual or institutional responsibility. This paper provides examples of these different perspectives and discusses the implications of multilingualism and work in a migration context.
