In anticipation of a new law that would regulate in detail, and in accordance with international standards and practice, the right of employees to strike, the author tries to consider certain important aspects of that right, as the basic form of collective action of employees. Therefore, the paper raises the issue of constitutionalization of the right to strike in domestic and comparative law, and at the same time problematizes the definition of the concept of strike by constitutional and legal norms. In order to better understand the problem, and in connection with the constitutionalization of the right to strike, using the comparative law method of research, special attention is paid to the constitutional guarantees of the right to strike in comparative law. Also, the author tries to theoretically determine the concept of strike, as well as to point out the important elements of the strike that are stated in certain scientific discussions. Finally, a critical review was given to the issue of regulating this right in our area in the period of self-governing socialism, when this right was not regulated by constitutional norms or a special law, and the similarities and differences between the concept of strike and the concept of work stoppage were analyzed.
