This thesis proposes a socio-economic analysis of the support provided in the associative sector to People living with HIV when looking for a job in France. On the one hand, it studies how the associative support is built and on the other hand how access-to-job paths integrates in the associative landscape. By opening the black box of the social accompanying, it completes the statistical and biographical approaches of support relationship that are built by the associative instituion through two monographs. Based on the coupling institutionalized theory, the stakeholders's text analysis - using the software Alceste - identifies the institutional part with regards to social construction in the access-to-job paths and shows a tension between deliberation and access-to-job within the associative support construction. The contextualized biographical analysis identifies the institutional factors of failure and access-to-job success. The speakability release and the skills that are acquired with the experience make easier and reinforce the access-to-job when social problems and attitude towards AIDS undermines it. Those analyses show that the associative support towards employment added-value includes the support relationship under collective dynamics by making it less individual, building deliberation arenas and by valuing the experiental knowledge.The thesis finally shows that associative instituions are difficult to modify and that the practises withstand to institutional changes dynamics while get nourished by it.
