Introduction: From Blaming Individuals to Understanding the System
In 2014, I published an initial article on mobbing – the phenomenon of collective harassment described by Heinz Leymann in the 1980s, whereby a group ultimately excludes one of its own members by designating them as a scapegoat. At the time, my analysis primarily drew on René Girard’s work on the scapegoat mechanism and the clinical observations gathered from my field interventions. Twelve years later, having accompanied over two hundred organizational crisis situations, I can see how much that initial perspective, while accurate, remained incomplete.
What I have learned since then is that mobbing is almost never an isolated phenomenon. It is the symptom of a deeper relational pathology, rooted in what I now call organizational psychological debts. More precisely, mobbing sits at the convergence of three dynamics that my recent research has enabled me to model: the accumulation of debts of place(the question of who is legitimate within the collective), the emergence of a group paranoid dynamic (the compulsive search for someone to blame in order to evacuate collective suffering), and the rupture of the psychological contractbinding the individual to their organization.
This article offers a thorough re-reading of mobbing through the lens of Integrative Contextual Intervention® (ICI®), the methodology I have developed to regulate complex psychosocial crises in organizations. The aim is not only to understand why a group comes to destroy one of its own, but above all to open pathways for intervention that go beyond merely sanctioning perpetrators or protecting the victim – even though both actions are necessary.
