In 2015, a new international integration economic association, the Eurasian Economic Union (hereinafter referred to as the EAEU), appeared on the economic and legal map of the world. Each member state of the EAEU, after gaining independence, as a result of the collapse of the USSR, independently formed a legislative framework in the field of labor, developed regulatory legal acts. Differences in the regulatory framework of the EAEU states, in particular, in the field of labor law, and their mutual economic integration, need to be compared in order to develop common principles, unification and harmonization of national legislation. In this regard, the article, based on the analysis of national labor legislation, assessed the prospects for regulating individual and collective labor relations and formulated conclusions on legal approaches to regulating social partnership relations, on the principles of the creation and functioning of trade unions and employers’ associations in the EAEU countries. In particular, the trade unions of the post-Soviet republics that are part of the EAEU have completely lost the right of legislative initiative, which corresponds to global practice. Currently, they can only make proposals for the adoption, amendment of regulations related to their area of competence. The position of trade unions as social partners on the adoption and amendment of labor legislation has ceased to be mandatory, and is often not taken into account by employers and public authorities.
