Mental health problems are, according to the World Health Organization, a major issue of humanity to address in the century to come. Work can constitute a major vector for the construction of mental health. However, having a job is not enough to guarantee people’s psychological health: good work conditions and organization are decisive concerning that issue. This oral paper explores the contribution of decent work to mental health amongst Quebec workers (Canada), considering also the relationship of these workers to their current job. Based on a psychosocial approach to decent work, this cross-sectional quantitative study was conducted by online questionnaire with 305 workers. Findings of SEM reveal a two-folded concept of decent work, which is predicted by socio-economic positions, and predicts in turn positive outcomes on relationship to current work and mental health. Questions raised about the differential effects on mental health of the dimensions of decent work that may or may not be related to instrumental indicators of job quality.
