This article is a reflection on institutional work with psychotic people. The myth of Sisyphus serves as a metaphor for the difficulties and possibilities one encounters in this work: on the one hand, the never-ending nature of the work, the laborious progress, the alienating dynamics of the institution; and on the other, the movement, the chances to meet one another. The movement of institutional psychotherapy offers tools for constant reinvention and endurance in this work. Clinical examples illustrate how this thinking tries to realise itself in the daily practice of the institution.
