This paper is built around the workers’ fundamental right to take collective action and collective bargaining. Although, this right is firmly embedded in the majority of labour law systems in the social policy (meaning labour law, too) of the European Union, it is worth analysing it separately with an independent meaning. We can approach this right from the fundamental rights, the fundamental treaties or from certain directives, so we can find several questions that are difficult to answer properly. These problems are mostly catalysed by the necessary collision between the need for socially motivated legal protection and the fundamental economic freedoms. In my research, I analyse this right – along with some other connected ones – with the help of the recent case law of the Court of Justice of the European Union and the European Pillar of Social Rights because the latter highlights the holistic approach in the current reforms of EU social policy.
