The Labour and Social Security Law Research Group (GREDTiSS) is a research group recognized by the Pompeu Fabra University (UPF) which has an active team of more than fifteen researchers at national and international level.

Historically, the group's collective research has focused on the analysis of political changes, labour reforms, the impact of new technologies, the decommodification of social rights, and the boundaries between formal and informal work. This trajectory has been consolidated through projects funded by the Ministry of Economy and Competitiveness, such as those dedicated to the Notion of worker and segmentation of social rights, New governance institutions in Work, or Convergences and divergences of collective bargaining systems (DER2015-69652-P).

Currently, GREDTiSS has evolved towards new transversal thematic axes that respond to the current challenges of the labour market, focusing its collective efforts on remote work, solidarity, environmental sustainability, and decent work. These commitments are materialized in our current research lines: on the one hand, the study of new organizational realities through the Remote Work project, led by Julia López López as PI. On the other hand, the commitment to a just ecological transition is reflected in the project "Reforzando los derechos de las personas trabajadoras en riesgo de exclusión social en la economía verde y circular" (PID2022-141180NB-I00), funded by MCIN/AEI and the EU FEDER fund, under the direction of Consuelo Chacartegui as PI. It is also relevant the participation of some of the group members in the European Research Council "Rethinking Work beyond productivism from labour law and its uses" (PI - Elise Dermine, ULB).

Regarding the scientific production resulting from these lines of work, special mention should be made of the collective's most recent publications, headed by the works of Julia López, Remote Work and Labour Institutions and Inscribing Solidarity (Cambridge University Press - CUP); and the monograph by Tirant lo Blanch editorial, Vulnerables en la economía verde y circular: una mirada jurídico-laboral by Consuelo Chacartegui. These works are part of a solid trajectory of prior international collaborations of the group, such as The Oxford Handbook of The Law of Work (Oxford University Press), The Idea of Labour Law (Oxford University Press), Rethinking Workplace Regulation (Russell Sage Foundation), or Resocialising Europe in a Time of Crisis (Cambridge University Press).

Finally, all this research expertise is directly transferred to teaching in the degrees in Law and in Labour Relations at UPF, where members of the group teach key subjects such as Individual and Collective Labour Law, Social Security Law, or Labour Procedural Law among many others.
