The described issues associated with organizational multilingualism point to effective ways of managing linguistically diversifi ed organizations.

Practical implications: The investigated topic can be interesting not only for those involved scientifically in management, linguistics and widely-understood social sciences, but also for practitioners working in companies with a complex cultural and linguistic structure. The described theory followed by the discussion help understand how heteroglossia may infl uence the development of organizations as well as its potential and how to avoid mistakes in managing organizations with a multidimensional linguistic capital.
