Why Timing Is One of the Most Critical Decisions in Mediation

Mediation is far more likely to succeed when it is introduced at the right moment. The same dispute that resolves quickly and constructively in mediation at one stage can be almost impossible to settle in mediation six months later, once positions have hardened, costs have mounted, legal advisers have become deeply invested in their clients’ positions and both parties have publicly committed to narratives that make compromise feel like defeat.

Timing cuts both ways. Introducing mediation too early, before the parties have a clear picture of their own position and what resolution would look like, can also be counterproductive. A party who has not yet fully understood the strength or weakness of their case may make concessions they later regret, or may resist settlement terms that were actually in their interest because they had not yet done the analysis to see it.

This chapter examines the timing question for both workplace mediation and employment mediation, and provides a framework for making the timing decision well.

Timing in Workplace Mediation

1. The earlier the better, with conditions

In workplace mediation, the general principle is that earlier is better. The longer a relationship difficulty is left unaddressed, the more entrenched the parties’ positions tend to become, the more the conflict spreads to colleagues around them, and the more difficult it becomes to find a resolution that both parties can accept. TCM Group, one of the UK’s leading workplace mediation providers, reports that disputes referred to mediation early are significantly more likely to resolve than those referred after a prolonged formal process has already taken place.

However, early mediation only works if both parties have enough clarity about what has gone wrong to be able to engage meaningfully with the process. Where a dispute has only just emerged and the parties have not yet had any opportunity to reflect on their own position, a brief pause before mediation can be helpful. The goal is to introduce mediation as soon as both parties are ready to engage, not before.

2. Before a formal grievance is raised

One of the most valuable windows for workplace mediation is the period after a conflict has become apparent but before a formal grievance has been raised. At this stage, neither party has committed publicly to a formal position. There is no written record of allegations that will need to be investigated or responded to. The parties retain maximum flexibility and control. Mediation at this stage has the best chance of producing a durable resolution that both parties genuinely own.

3. After a grievance has been raised but before a formal hearing

Where a formal grievance has been raised, mediation is still available and often appropriate. The formal procedure should be paused while mediation takes place. If the mediation resolves the dispute, the grievance can be withdrawn. If it does not, the formal procedure resumes. Many organisations now have policies that explicitly provide for mediation to be offered at this stage before a formal hearing takes place.

4. After a formal investigation has concluded

Where a formal investigation has been completed, the findings are known and the disciplinary process is underway or concluded, there may still be a valuable role for mediation, particularly where both parties will continue to work in the same organisation. The mediation at this stage is not about relitigating the investigation findings but about how the parties move forward given those findings.

Timing in Employment Mediation

1. Before a tribunal claim is lodged

The best time to attempt employment mediation is before a tribunal claim is lodged. At this stage, neither party has incurred significant legal costs. Neither party has committed to a formal legal position in writing. The ACAS early conciliation process, which is a mandatory step before lodging most tribunal claims, provides a structured opportunity for this. Private employment mediation at this stage can be highly effective, particularly where the parties have a reasonably clear sense of their respective positions and what settlement might look like.

2. After a claim is lodged but before the hearing

The majority of employment tribunal claims that settle do so in the period between the claim being lodged and the hearing taking place. This is the most common window for employment mediation in practice. Both parties have a clearer picture of their legal position by this stage, having seen each other’s pleadings and, increasingly, each other’s documents through the disclosure process. The hearing date creates a natural deadline that focuses minds and can motivate movement on both sides.

3. Avoiding the point of no return

In employment mediation, there is a point at which the costs and commitments involved in pursuing the claim to a hearing begin to take on a momentum of their own. Legal fees have been incurred. Witnesses have been prepared. Both sides have invested emotionally and financially in the litigation. At this point, settling through mediation can feel like accepting defeat, even where it is objectively the better outcome. Introducing mediation before that point is reached is almost always preferable.

4. During a hearing

It is also possible, and not uncommon, for settlement discussions to take place during a tribunal hearing itself, sometimes facilitated by ACAS or through private discussions between the parties’ representatives. This is a late stage at which to be attempting mediation, and the costs and stress of the hearing itself will already have been incurred, but it remains a valid option and one that both parties should keep open throughout.

Signals That the Moment Is Right

The following signals, whether in a workplace or employment context, often indicate that the moment is right for mediation.

• Both parties express a desire to resolve the matter but cannot see how to get there without help.
• The conflict is beginning to affect the wider team, productivity or the organisation’s reputation.
• Legal costs are mounting and neither party feels the outcome of formal proceedings is sufficiently certain to justify the expenditure.
• One or both parties has indicated a willingness to consider settlement or a change in working arrangements.
• A formal procedure is approaching a stage that will be difficult or impossible to reverse, such as a disciplinary hearing that may result in dismissal.
• The parties are exhausted by the conflict and both want it to be over.

Signals That the Moment Is Not Yet Right

• A formal investigation into serious allegations is still ongoing and the findings are not yet known.
• One party is not yet willing to engage in good faith and needs more time or a change in circumstances before they will be ready to do so.
• The parties are so early in the dispute that neither has a clear picture of their own position or what resolution would look like.
• Safeguarding concerns remain unresolved and must be addressed through appropriate processes before mediation is appropriate.
• There is an urgent need for interim measures, such as a temporary change to working arrangements or suspension, that must be addressed before mediation can usefully take place.

Once timing has been addressed and both parties are ready to engage, the next question is who should conduct the mediation. That is covered in Chapter 6. If you need guidance on whether the timing is right for mediation in your situation, contact Robin for a confidential preliminary discussion.
