Introduction. The world economic crisis of 1900-1903, which was accompanied by a crisis in the social sphere and resulted in the emergence of protests among the working class, became one of the significant factors that led to the First World War of 1914-1918. Therefore, there was the keen necessity to form a new international law and order with social and economic components. The League of Nations’ creation ensured its establishment, and the social and economic cooperation of states was concentrated within the framework of the ILO, in order to resolve social conflicts, protect the rights of workers, improve working conditions and increase their living standards. However, the continuation of the crisis was the next stage of the Second World War of 1939-1945 and taking into consideration the duration of this crisis in the XXI century the threat of a new world war in the nearest future cannot be excluded. The instability of international relations is the result of the destruction of the international law and order, which is replaced by protectionism in the form of regionalism. Conclusions. Within the framework of international organizations, in particularthe UN, ILO, EU a set of anti-crisis measures is adopted in order to overcome the consequences of the global crisis. However, they are not sufficient, often improvisational ,and the urgency of crisis management requirements leads to non-optimal solutions. Current legal order cannot be considered without the social and economic rights and activities of the ILO. The organization is designed, in particular, to ensure the establishment of universal peace based on social justice; develop and implement norms and principles in the field of labour; provide decent employment and social protection for all; develop international measures and programs for the implementation of human rights, improving working and living conditions; develop international labour standards etc. The states’ efforts to overcome this crisis should cover all levels of cooperation between states in the social and economic sphere, the adoption of appropriate effective measures, and decisions that would be characterized not situationally, but by systematic preparation for various crisis situations, including more active application of forecasts and different scenario planning.
