The purpose of the article is to study the political and legal prerequisites and organizational and legal foundations of the activity of the prosecutor's office for labor cases in the USSR during the entire period of its operation (1925–1931). There was applied a systematic approach to knowledge of ideology, legislation and law-enforcement documents. The methods used: general philosophical method of dialectics, general scientific methods of analysis and synthesis, special methods: historical, hermeneutic and formal-legal. It was proved that the supervision of compliance with the law in this period should be considered partly as a component for labor rights protection and as a way of proper working conditions securing to ensure realization of the work duty by citizens. It was found out that the purpose of labor care was to ensure the regime of "revolutionary legality" in the field of labor, i.e. strict compliance with legislative acts, and directives of the Communist Bolshevik Party and the government in order to satisfy the interests of the proletariat dictatorship state. The function of general supervision of the prosecutor's office, which was implemented in the Ukrainian SSR, other republics of the USSR and in the countries of the "socialist camp" based on the Soviet model aimed at protecting state interests in the person of its party's leader. Such a function is not typical for democratic countries as it contradicts the principle of power-sharing. It was proved that the function of the general supervision of the prosecutor's office on labor cases was reduced to the duplication of control and supervisory powers of labor inspectorates, conciliatory and judicial bodies.
