Abstract
The dynamic technological transformations that are taking place in the third decade of the twenty-first century, described as the Fourth and even Fifth Industrial Revolutions, pose significant challenges for community partners who act in labour relationships. Transparency and the related right to information are some of the factors that define a democratic state under the rule of law. This also applies to labour relationships as widely understood. The regulations of collective employment law grant various rights in this respect to entities that represent staff, who may, among other things, demand information on the use of artificial intelligence by the employer in the work environment. In the Polish labour law system, the widest scope of competences in this regard is granted to trade unions. This article focuses on the legal and functional aspects that are related to the transfer of this type of data.
