From the analysis of work situations, it is observed that the management of work is not the responsibility of the individual but of relatively pertinent collective entities. They are what enable the renormalizations, building talks so that the renormalizations do not occur in an individualistic movement, but in the synergy of the construction of a historical heritage. Reflexions concerning two services of a public hospital in Brazil are retaken and, with an ergological perspective, it is discussed that these collective entities are not predetermined, as they emerge from the debates of norms and values that occur in developing activities. In the service of marking of exams and the ward service, the norms correspond simultaneously to norms related to procedures and organization of work, but they also correspond to the singular treatment of specific situations of the patients who pose a debate without measurement scale (the common good) and measurable values (market). The process that happens has consequences in the work of managers and workers of the services, and also the work of the intervener-ergologist, for whom it's a primary task to better understand collectively the interrelationship of these values and how to better work with them in the management process.
