This research moves from the general hypothesis that assistance provided to a person needing support, and the effort needed to articulate work and care may, under certain conditions, become a factor in carers' inequality and vulnerability. The article presents the results of qualitative research conducted in Quebec, Canada, with carers of older people who also have full-time paid employment in the labour market, and on professionals providing these carers with services. It considers how the services offered to carers have been implemented and how they can affect carers' daily lives.
