This study aims to explore how the application of Business English as a Lingua Franca (BELF) is perceived among the employees at a chosen company, exploring to what extent BELF is used, and identifying opportunities and challenges of BELF. Using a qualitative research methodology conducted through semi-structured interviews, consisting of six participants, the study delves into the usage of BELF in a bigger Swedish company, how the employees experience it, and what factors matter for its outcome. The results show overwhelmingly positive experiences of BELF among respondents, primarily due to its necessity and appreciated utility in facilitating communication with customers and colleagues who do not share the same mother tongue, emphasizing the significant role of English in diverse business contexts. However, despite the generally positive outlook, challenges such as multilingual meetings, code shifting, misunderstandings in different contexts, and a restricted vocabulary, are identified.
