Introduction. Today's turbulence is constantly changing socio-labor relations, which is manifested in the spread of atypical forms of employment, narrowing of social security of workers, the formation of a new world division of labor, which ultimately affects the sustainability of development as a country, employee welfare. Such transformations proportionally change the level of social security of the country and workers, but the vector of these changes is not always aimed at improvement. Unfortunately, the existing theoretical and methodological approaches to assessing the condition of socio-labor relations do not allow to predict deeper changes and consequences for the further development of society, the country, so it is important to explore them through the prism of social security. Purpose. The aim of the article is to study the transformations of socio-labor relations under the pressure of the new socio-economic reality (pandemic COVID-19) and the possibility of implementing their adaptive mechanisms to maintain a sufficient level of social security. Method (methodology). The methodological basis of the study is formed by general scientific methods - analysis, generalization, theoretical foundations of the concepts of decent work, social responsibility and green economy. The assessment of socio-labor relations in the context of their ability to form the preconditions of social security was carried out according to the author's method, which allows to identify reference points for the emergence of risks and dangers. Analytical calculations were performed using statistical methods, using official statistical reports of international organizations, scientific developments of leading scientists in the field of social security and the essence of social and labor relations. Results. The connection between the development of social and labor relations and the formation of preconditions for social security is revealed. Calculated objective indicators of socio-labor relations that directly affect the level of social security, such as financial well-being of employees, the potential for human capital development (wage potential) and the risks of job loss, as well as subjective indicators - life satisfaction, mental health and confidence in the future (development, income expectations). It was found that the social partners in Ukraine have not been able to achieve a high level of collaboration, so the current model of socio-labor relations does not fully provide sufficient social security for workers and the country.
