Purpose This paper aims to identify communicative practices emerging from the management decision to implement English as a corporate language, assessing their implications for social interaction and relationships within the multilingual workplace. Design/methodology/approach An exploratory study based on qualitative research interviews was used. Findings The analysis highlights the discrepancy between a general openness to the use of English as a corporate language in Danish organisations and language users' communicative practice. This leads to the identification of language clustering and thin communication as characteristic behaviours within the multilingual workplace. Research limitations/implications The interviews were performed in Danish organisations alone. New research is required in order to apply the findings to other linguistic or national settings. Practical implications The research identifies two barriers to employee interaction within the multilingual workplace. This is relevant in relation to language planning as well as diversity management. Originality/value The paper is original in its application of a sociolinguistic perspective to employees' linguistic practice. This points to the importance of language as a social resource and the possible limitations of corporate language policies. © 2009, Emerald Group Publishing Limited
