This study examines the problematic issues of improving labor legislation. At the present stage of development of market transformations in the Republic of Kazakhstan, as well as taking into account the entry of the Republic of Kazakhstan into the Eurasian Economic Union, the problems of reforming labor legislation are of crucial importance. This necessitated the emergence of new views on the legal regulation of public relations in the field of the realization of the right to work. In this regard, it becomes urgent to rethink many fundamental provisions of labor law, and among them, not the last place is occupied by the problems of improving labor legislation in various areas of labor relations in a market economy. At the present stage of development of the Republic of Kazakhstan, labor legislation should guarantee the implementation of a wide range of not only labor, but also other socio-economic and personal rights and freedoms. Despite the relative research, the study of issues of further improvement of labor legislation does not lose its relevance, taking into account the fact that both the legislation of the Republic of Kazakhstan in general and labor legislation in particular are constantly developing and need further development and improvement. The purpose of the study is a comprehensive study of the current state of the labor legislation of the Republic of Kazakhstan and the definition of the main directions of its improvement in the light of the protection of labor rights. The methodological basis of the research is based on modern methods of cognition: dialectical, formally logical, historical, comparative legal, analytical-synthetic, system-structural, logical-legal. The article substantiates the need for new theoretical and methodological approaches to the consideration of the main directions of improving the labor legislation of the Republic of Kazakhstan, in connection with which, there is an urgent need to study labor legislation, which is designed to ensure the labor rights of man and citizen, from the perspective of its further improvement.
