Professionals working in international companies in Sweden are expected to speak, read, and write in Swedish and English in their daily work. This article discusses professional writing in different languages. Through the use of methods from linguistic ethnography, we aim to enrich the understanding of workplace literacy by studying writing and texts in multilingual business contexts. Our results show that professionals are expected to navigate between a translanguaging mode and a more monolingual mode in everyday communication. Also, when they opt for producing monolingual texts, literacy practices that surround those texts are often multilingual. Moreover, they imagine a future, secondary audience for their texts, often resulting in the choice of English for reaching out, or in the choice of Swedish as a way of keeping matters local. Knowing when to choose a translanguaging mode or a more monolingual mode is a necessary skill or competence in this type of workplace. Our results also show that the use of multimodal resources includes the material placement of texts, and that old materialities such as pen and paper are still essential. Different linguistic and semiotic resources are used, including resources from academic, business and personal discourse.
