In Marseille, negotiation often takes place in a dense environment: multi-partner projects, operational constraints, tight deadlines, and overlapping social or contractual issues. In this context, improvisation is costly. What makes the difference is preparation, framing, and the ability to hold a position without unnecessary escalation.
We work in Marseille with executives, managers, and teams (HR, legal, procurement, sales) facing situations where the exchange becomes unstable: sensitive cases, internal tensions, labor negotiations, strategic contracts, or difficult arbitrations.
At NON | NÉGOCIABLE, we train decision-makers and field actors in strategic negotiation and negotiation under pressure. The goal is simple: to provide you with a method applicable to your real-world cases.
This page is the local version of our negotiation training. If you are looking for an intervention in Lyon or Paris, you can also consult our dedicated pages: negotiation training in Lyon and negotiation training in Paris. All our services are part of our professional negotiation approach.
Why train in negotiation today?
Because power dynamics are permanent within companies:
- Between management and labor unions,
- Between support and operational functions,
- Between employees and managers,
- Between companies and suppliers, clients, or regulators.
Negotiation is everywhere. And it is not a secondary "soft skill." It is a lever for performance, internal cohesion, and organizational resilience.
Training your teams in negotiation means giving them:
- The ability to say NO without blocking everything,
- The tools to defend a firm position without breaking the dialogue,
- A clear method to obtain solid results even in tense contexts.
When training makes a real difference
We typically intervene when organizations encounter situations such as:
- Labor negotiations that stall or become radicalized,
- Managers exposed to chronic internal conflicts,
- Leadership faced with contractual or partnership deadlocks,
- HR or legal teams caught between human constraints and strategic imperatives.
In these contexts, the issue is not "communicating better," but holding a line, anticipating adverse reactions, and structuring the exchange.
A radically different approach
Our method is born from the field. It combines:
- The founder's experience as a mediator in crisis negotiations (National Police, labor disputes, high-risk contexts),
- Insights from research in law, strategy, and negotiation psychology,
- Excellence models from international practices (Harvard Negotiation Project, crisis intervention techniques).
No PowerPoint slide readings. No HR jargon. Only real cases, intense role-playing, and unfiltered feedback.
Your team leaves equipped, structured, and more confident.
What classic training fails to prepare for
The majority of negotiation training relies on ideal models: rational parties, converging interests, cooperative climate. Reality is often different:
- Strong emotions,
- Asymmetrical power balances,
- Reputational or precedent-setting stakes,
- Pressure from time or the collective.
Our training integrates these parameters. It relies on strategic negotiation and operational negotiation techniques to prepare your teams to hold a position without wearing out or losing their way.
What your teams will master after the training
- Preparing for a negotiation by identifying true red lines,
- Setting a clear framework and holding it over time,
- Using concessions as leverage, never as a reflex,
- Dealing with pressure without overreacting,
- Exiting a negotiation with an assumed decision.
