The purpose of the paper is to identify the main problems related to the functioning of trade unions in capital groups. In particular, the paper deals with a sense of fairness, coop­eration, and the importance of profit distribution in terms of bargaining positions. The study included four different trade unions. Interviews were conducted with 35 union’s representatives and with 5 top managers (members of the board). The initial stage of the study was followed by inter­views with representatives of the top management bodies of a few capital groups.
