The article deals with the comparative legal research of the current labour legislation of each of the 28 EU member states with the Directive 2019/1152 of 20 June 2019 on transparent and predictable working conditions in the European Union. The relevance of the research topic is because after the adoption of Council Directive 91/533/EEC in the EU, a number of acts of primary and secondary legislation were adopted that significantly change the content and scope of labour rights of workers. These are, in particular, The Maastricht Treaty, The Treaty of Amsterdam, The Treaty of Nice and the Treaty of Lisbon. Furthermore, on December 7, 2000, the Charter of Fundamental Rights of the European Union was signed, and on December 17, 2017, The European Parliament, the Council and the Commission solemnly proclaimed the European Pillar of Social Rights. As a result, collisions arose between the above Acts and Directive 91/533/EEC, which required the adoption of a new Directive 2019/1152 and a comparative legal analysis of this Directive with the current labour legislation of each of the 28 EU member states.
