This chapter examines the language ideologies utilized in linguistic practices in multinational companies.Using language management framework, we address the question how language ideologies are connected to language management, which entails three more specific questions: 1) How do language ideologies underlie/guide organized management? 2) How do language ideologies underlie/guide simple management? 3) What does the relationship look like between language ideologies underlying simple management and those underlying organized management? The analysis is based on research conducted in a German-based multinational company in the Czech Republic, in which the language-ideological constellations involve Czech, English, German, and Vietnamese.
