The Power of Shuttlemediation
Talking without being in the same room.
Sometimes a conflict has escalated to the point where the parties can no longer bear to face each other. Sitting down together only makes things worse. Tensions rise, people become defensive, and what was intended as an opening comes across as an attack. That does not mean, however, that a resolution is out of reach. In shuttle mediation, the parties remain in separate rooms while the mediator moves back and forth between them. It may sound cumbersome, but international research shows that, in deadlocked disputes, this approach often leads to a resolution more quickly.

What is shuttle mediation?
Shuttle mediation: resolving conflict without sitting at the same table
Shuttle mediation is a form of mediation in which the two parties do not sit together in the same room. They are in separate spaces — physically or online — while the mediator moves back and forth between them.
The mediator communicates proposals, tests how messages are received, removes unnecessary sharpness from communication and looks for the space where both sides can find common ground.
The approach originates from diplomacy, where negotiators have worked for decades by moving between parties who are unwilling or unable to communicate directly [4]. Within mediation practice, it has developed into a fully recognized method — not merely a last resort.
In many cases, mediators intentionally alternate between joint sessions and separate conversations, known as caucus-sessions, depending on what the situation requires at that moment [8].
When is it chosen?
The choice for shuttle mediation depends on the situation, not on a fixed rule. There are several moments when it clearly provides added value.
The first is when a joint conversation only makes the conflict worse. If every confrontation leads to escalation, separating the parties removes direct friction. Research on workplace mediation indicates that being in separate rooms reduces emotional pressure and prevents direct confrontation, allowing people to express their true concerns more freely [7].
The second situation concerns loss of face. During a face-to-face meeting, people often avoid making concessions because they do not want to appear weak in front of the other person. A concession can then feel like a sign of weakness. In a separate conversation, however, someone can think out loud, share doubts, and explore possibilities without the other party observing. This is precisely where the flexibility emerges that often remains hidden in a joint session [1][8].
The third situation is safety. In cases involving a power imbalance, intimidation, or a history of inappropriate behaviour, sitting together at the table is not desirable and can sometimes be actively harmful. A review of research into shuttle and online mediation for separating couples with a background of domestic violence shows that separate conversations can then provide a serious and defensible alternative [5].
How does it work?
A shuttle mediation begins like any other mediation process, with an intake and a clear agreement on confidentiality. The mediator speaks with both parties, often separately, and identifies what is happening, what is at stake, and what each person truly needs.
Then the shuttle process begins. The mediator meets with one party, listens, asks questions, and helps clarify what really matters. The mediator then brings this information to the other party, in a way that can be received constructively. Not every statement is transferred word for word. The mediator removes the sting from accusations, translates blame into underlying interests, and keeps the conversation focused on the issues at hand.
What stands out in the research is that the purpose of these separate conversations matters. A field study on workplace conflicts in the Netherlands showed that a preliminary private meeting is most effective when the mediator uses it to build trust and prevent loss of face, rather than immediately trying to resolve the substance of the dispute [1]. Mediators who used the separate session to create calm and build trust reached better and more sustainable agreements than mediators who immediately turned it into a negotiation. Broader analyses of workplace and family mediations confirm this picture: a separate conversation beforehand, focused on building rapport, improves the quality of the outcome [2][3].
The shuttle process continues until a workable proposal is reached. Sometimes the case still ends with a short joint closing meeting once tensions have decreased enough. In other cases, the entire process remains separate until the end and the agreement is confirmed in writing. Both approaches can be considered successful outcomes. Research in restorative justice practices shows that even without a joint conversation, one party’s message can still reach the other and lead to recognition and understanding [6].
The mediator’s experience plays a crucial role in this process. The same research shows that speaking with parties separately works particularly well when handled by an experienced mediator [1]. It requires someone who can carefully filter messages, maintain trust on both sides, and prevent separate conversations from reinforcing mistrust instead.
A real-life example
An employee has been on sick leave for several months following a serious conflict with a manager. A complaint has been filed regarding intimidating behaviour. The employee no longer wants to be in the same room as the manager and becomes distressed even at the thought of having a joint conversation. Returning to the team is no longer a realistic scenario for either party. The remaining question is how to end the employment relationship in a respectful way. The occupational health service sees the absence process becoming stuck and refers the case for mediation.
This is precisely a situation where shuttle mediation is appropriate, because the working relationship has come to an end and there is no longer a need to restore the relationship. A joint meeting would place the employee back in the position that led to the complaint and would likely cause the mediation to fail before it even begins.
The mediator speaks with both parties separately. With the employee, the initial focus is on acknowledgement and safety: what is needed to bring this situation to a proper conclusion. The employer, also spoken to separately, is primarily seeking a correct resolution without legal consequences and with consideration for the team’s reputation. The mediator moves back and forth between both sides, explores proposals regarding the termination conditions and the tone of communication to the team, and keeps the employee away from any direct confrontation. An agreement is reached regarding the end of the employment relationship and how this will be communicated. The parties never meet at the same table. The case is completed within Result ADR’s usual timeframe, within six weeks.
This example has been anonymised and compiled from common situations. Confidentiality is a strict boundary in mediation, including in this case.
Why a mediator sometimes decides against it
Shuttle mediation comes with a cost, and a good mediator takes that into account. The main concern touches the core of the profession: impartiality. As a party, you do not know what is being discussed in the other room. The mediator manages the entire flow of information, and even the appearance that the other party is receiving more time or attention can undermine trust. An unequal division of time — an hour with one party and fifteen minutes with the other — can quickly feel like favouritism, even when the mediator remains substantively neutral [9][11].
In addition, the mediator gains significant influence over how messages are conveyed. A statement may unintentionally come across as sharper or softer, or lose its context. Parties may begin to rely on the mediator as a messenger, creating the risk that the mediator shifts into the role of negotiator or rescuer rather than remaining a neutral facilitator [10].
Something else is also lost that often creates breakthroughs in mediation: direct contact. Tone and body language disappear, along with the moment when someone truly hears the other person and adjusts their perspective. What remains is often a series of exchanged proposals, without the shift in understanding that a joint conversation can create [9][10].
As a party, it can also be tempting to present the situation more favourably when the other person is not listening. Lack of transparency can fuel mistrust: what is being discussed in the other room, and will the mediator still be on my side afterwards? [11]
That is why shuttle mediation is not a standard approach. It is most suitable in cases where safety, a power imbalance, or the definitive end of a working relationship outweighs the value of direct conversation. When parties still need to continue working together afterwards, a joint approach usually works better, because rebuilding the relationship is then the main objective.
In conclusion
Shuttle mediation is a deliberate choice that, in the right cases, can lead to calm and agreement more quickly than a conversation that the parties are unable to handle. Research consistently points in the same direction: a safe, separate environment reduces pressure, brings underlying interests to the surface, and protects people from loss of face. In the hands of an experienced mediator, it provides an effective path towards resolution.
At Result ADR, more than 90% of cases are successfully resolved, with an average duration of less than six weeks and a rating of 9 from parties afterwards. Whether that success is achieved at the table or through shuttle mediation between two separate rooms matters less to us than achieving it.
