The purpose of this article is to analyse the process of constitution of a group from data collected in a research with a group of 20 public workers, who took part in a program of manager formation at work. Since they were together during two weeks in the same place the constitution of meaningful relations among these people was favoured. The record of these relations was considered relevant material to the investigations of their movements. What sat off the constitution of the group was the mutual recognition of people who felt belonging to a collective because they perceived themselves sharing something which was meaningful to them. From the meeting onwards they promoted simultaneously continuities and ruptures with the past history, developing their own way, which is marked by the present singularities and the collective performance there produced.
