The paper analyses the challenges posed by the transformations of the world of work to the national systems of labor law and social security and the different policies adopted by the major States in responding to these challenges.The major issues are discussed commenting the reports of the seven research groups of the ISLSSL which ha explored the frontiers themes of our field.
After analyzing the impact of the digital revolution on the various dimensions of work including the legal categories traditionally applied to the employment relations,the paper stresses the need to find new criteria for regulating and protecting the various types of platform based workers.A more effettive and integrated approach is also needed to workers involved in the informal economy which amounts to over 70% in developing countries but is also diffused in the advanced areas of the world.
The systems of social security are also challenged to find new solutions capable of combining financial sustainability with social adequacy:in particular the extension of social protection ,fiscally supported , and welfare measures such as minimum income aimed at fighting poverty ,possibly coordinated with active labor policies.
Two further themes are discussed :a) the role of national states in regulating transnational labor relations ,via social clauses in international treaties and diffusion of transnational collective bargaining ,b)the impact of the decentralization of collective bargaining to the enterprise level on employment conditions ,including payment by results and company welfare.
Finally the essay advances some hypothesis for further research and for discussing new legal instruments and policies necessary to meet the future economic and social challenges.
