This article deals with the strategies of linguistic coordination of four enterprise models located in Catalonia (Spain), unequally a¤ected by the mobility of factors of production. We analyze the linguistic regimes of each one of these models paying special attention to the linguistic criteria of selection and promotion of personnel. Based on the data obtained, we identify two typologies of companies, each one with a di¤erent degree of emphasis on communicative e‰ciency and on strategies of control through practices of linguistic discrimination.
