Coalition-Building / Mobbing

One-liner: A private grievance becomes a group campaign, and the target is outnumbered before they know there’s a fight.

Also known as / related terms: Mobbing, workplace mobbing, ganging up, group-target bullying, Leymann’s model.

What it is: “Mobbing” was named by Swedish researcher Heinz Leymann, who documented a recurring pattern in the 1980s: systematic hostile communication directed at a single individual by multiple colleagues or superiors acting in concert, rather than one bully acting alone. Leymann’s model describes a four-stage escalation: an unresolved triggering conflict; a stage where a group forms around the target and aggression/stigmatization begins; a stage where management hears the group’s narrative first and mislabels the target as “the problem” (often a performance or personality issue); and a final stage of expulsion, resignation, termination, or extended leave. What distinguishes mobbing from ordinary conflict is the coalition itself: a personal disagreement between two people is recruited into a shared, group-endorsed narrative that becomes self-reinforcing, because each new person who joins in makes the target’s account look more like the outlier position.

What it looks like (workplace): After one interpersonal disagreement with a peer, the target notices that several colleagues who were previously friendly begin excluding them from informal conversations, meetings get scheduled without them, and their manager starts referencing “concerns the team has raised”, plural, unspecified, about the target’s attitude. No one individual behavior is dramatic; the pattern is the coalition, not any single incident.

Why they do it: Group participation diffuses individual responsibility and legitimizes the original instigator’s narrative, “it’s not just me who thinks this”, while making the target’s isolation feel like independent confirmation rather than an orchestrated pattern.

How to protect yourself:

• Identify and preserve the earliest, single triggering incident and your own account of it in writing, Leymann’s model shows the origin conflict is often forgotten by the time the coalition has formed, and having it dated and factual matters later.
• Seek one or two individual, private conversations with people who joined the exclusion, coalitions often include people who don’t fully know the original story and may reconsider once spoken to directly.
• Escalate to HR or leadership using specific, dated, factual incidents rather than “the team doesn’t like me”, mobbing narratives thrive on vagueness, and vagueness is what you want to deny it.
• Recognize the expulsion stage as a real risk, not paranoia, if the pattern matches Leymann’s later stages (management repeating the group’s framing, formal performance scrutiny appearing without prior history), treat it as a serious organizational-exit risk and seek documentation, union, HR, or legal guidance proactively rather than waiting it out.
