In this article we elected communication at school as the discussion focus, in particular the one which apparently would not be held at work situation - the teachers' room interactions, where teachers meet during the break. From the way the notice board is used we intend to engage in a controversy about the relations between the professionals and the meanings of work. The perspective is to analyze the communication devices holding attention to the produced effects in a truth regime that authorizes a way of working which increases the exclusion of students and teachers in their ability on practice management. First of all we will situate the reader in the problematic and reference adopted. Then, we will go through the controversy of work, health and knowledge production concepts, bringing the notice board as a processes analyzer. Finally, we will point out leeways and other formation possibilities.
