Female workers who provide homecare for the elderly suffer from several handicaps on the labor market, and so appear to be a population with low (social and occupational) assets for collective action. However, we observed during our field work a collective action against the phone time clock promoted by the director of the organization. Therefore, in this article, we wish to show that it is our detailed knowledge of the work experience of these homecare workers that made us able to reveal the protest, its specific form and its causes. At first these workers use very discreet protest practices in order to protect themselves. Then, their resources are collective and related to precise occupational contexts: it is during their work that these women mobilize occupational and local resources for collective action.
