This study aims to identify the emotion work of accompanying citizens (ACs) as part of a project for community integration offered to people with a mental health problem. From the perspective of the psychodynamics of work, a case study was carried out to understand the subjective reality surrounding the citizen accompaniment. The results show that sources of pleasure and suffering are associated with the practice of accompaniment, including a sense of usefulness and action in a context of uncertainty. In the context of caregiving, continued activity and confronting constant emotional issues is possible through the development of individualized defensive strategies. Citizen support is a complex caregiving practice that mobilizes emotions.
