The object of the paper is a slaughterhouse and the production of action within it. An historical study has revealed how a general process of violence and death repression had led to the construction of hidden places: the slaughterhouses. An ethnographic study shows that the members have promoted an implicit code which define different positions in the group connected to the tasks accomplished. The spatial positions during the work refer to moral positions within the group. The “killers” operate and remain, most of the time, in the “killing” place, whereas the “non-killers” quasi never penetratre into the killing space and stay away from the killers. The questions of deviance and social reaction within an implicit normative context is discussed.
