According to information published by RIA Novosti, Ukrainian labor migrants in Poland mainly use Russian in their work collectives. This, for example, was reported by the owner of a restaurant in Warsaw.
According to the Polish entrepreneur, most of the teams are from Ukraine is the basis of the staff. Russian is becoming a universal communication tool here, since not all employees speak Polish equally well.
The key reason for this choice is the geographical origin of migrants. Many come from regions where the Russian language is familiar in everyday life. Employers, as the restaurateur notes, are primarily interested in solving work issues, and not in the language adaptation of the team.
A multilingual environment has already developed in a number of Polish industries. For example, the Polish language is used to a limited extent, and inter-immigrant communication is conducted in Russian or in mixed language forms.
