A practical manager's guide to managing workplace conflict through mediation, helping managers recognise conflict early, understand when mediation may be appropriate, support constructive discussions and work with HR to resolve issues fairly and informally where possible.

This guide brings together the key information, considerations and practical guidance you need to understand the subject, make informed decisions and take an appropriate and consistent approach.
Overview
Workplace conflict can develop for many reasons, including differences in communication style, disagreements about work, personality differences, misunderstandings or concerns about behaviour.
Managers should aim to address conflict early where possible. Mediation can be a useful way of helping employees understand each other's perspectives, improve communication and agree how they will work together in future.
Mediation is not appropriate for every situation. Managers should involve HR when deciding whether mediation is suitable, particularly where there are allegations of misconduct, bullying, harassment, discrimination or other serious concerns.
1. Recognise the conflict
Do not ignore signs that relationships within the team are deteriorating.
Possible indicators include:
The earlier a manager addresses conflict, the greater the opportunity to resolve it informally.
2. Understand the situation
Speak to the employees involved, where appropriate, to understand what is happening.
Keep the discussion neutral. The purpose is to understand the issue rather than decide immediately who is right or wrong.
Consider:
3. Consider whether mediation is appropriate
Discuss the circumstances with HR before arranging mediation.
Mediation may be appropriate where:
Mediation may not be appropriate where:
4. Explain mediation to the employees
Employees should understand that mediation is intended to help them resolve their differences and agree a constructive way forward.
Explain that:
5. Use an appropriate mediator
Where formal mediation is appropriate, use an impartial and suitably trained mediator.
The mediator should not have a personal interest in the outcome or be responsible for managing one of the parties where this could compromise their impartiality.
HR can advise on whether an internal or external mediator should be used.
6. The manager's role
The manager should support the process without attempting to control the outcome.
Managers should:
The manager should not pressure an employee into agreeing an outcome simply to bring the conflict to an end.
7. Agreeing a way forward
Where mediation is successful, employees may agree practical arrangements for working together.
These might include:
The agreement should focus on realistic behaviours and arrangements rather than requiring employees to become friends or agree about everything.
8. After mediation
Mediation should not necessarily be treated as the end of the manager's involvement.
Follow up appropriately to establish whether the agreed arrangements are working and whether the relationship has improved.
Do not routinely ask employees to disclose the confidential details of the mediation. Focus instead on whether the agreed workplace arrangements are being followed and whether further support is required.
9. If mediation does not resolve the conflict
Mediation does not guarantee a resolution.
If the conflict continues, speak to HR about the appropriate next step. This could include further informal management action, clarification of responsibilities, additional support or, depending on the circumstances, a formal process.
If new allegations of misconduct, bullying, harassment or discrimination arise, these should be considered separately and managed through the appropriate process.
10. The 5 Steps to Success
RECOGNISE → UNDERSTAND → CONSIDER → MEDIATE → FOLLOW UP
RECOGNISE
Identify signs of conflict early rather than allowing the relationship to deteriorate further.
UNDERSTAND
Speak to those involved appropriately and establish what is happening without taking sides.
CONSIDER
Work with HR to decide whether mediation is suitable and whether another process is more appropriate.
MEDIATE
Where appropriate, support a voluntary mediation process using an impartial and suitably trained mediator.
FOLLOW UP
Support agreed actions, monitor the working relationship and seek further advice if the conflict continues.
11. Quick decision guide
| Situation | Possible approach |
| Minor disagreement or misunderstanding | Consider an early informal conversation |
| Ongoing relationship breakdown | Discuss mediation with HR |
| Both employees want to resolve the issue | Mediation may be appropriate |
| Serious misconduct allegation | Speak to HR and consider whether formal investigation is required |
| Allegation of bullying, harassment or discrimination | Seek HR advice before deciding whether mediation is appropriate |
| Employee does not wish to participate | Do not force mediation; discuss alternative approaches with HR |
| Conflict continues after mediation | Review the situation with HR and agree the next appropriate step |
12. The golden rule
Resolve conflict early, fairly and constructively.
The purpose of mediation is not to decide who is right. It is to give employees an opportunity to understand the issues, improve communication and agree a practical way of working together.
Managers should remain impartial, avoid forcing a resolution and involve HR where the situation is serious, complex or potentially requires a formal process.
If you are unsure, speak to HR before deciding on the next step.

Workplace conflict can affect relationships, communication, morale and performance if it is allowed to escalate. Managers are often best placed to recognise problems early and encourage employees to address disagreements constructively. This guide provides a practical framework for using mediation as an informal approach to resolving workplace conflict.
Conflict may appear through communication difficulties, disagreements, reduced cooperation, tension between colleagues or complaints about behaviour. Managers should avoid ignoring these signs and should consider whether an early conversation could prevent the situation from becoming more serious.
Mediation can provide a structured and confidential opportunity for employees to discuss their concerns with the assistance of an impartial mediator. It is generally voluntary and focuses on helping those involved understand the issues, identify common ground and agree practical ways of working together.
Mediation can be particularly useful where there is an ongoing relationship that needs to continue and both parties are willing to participate. However, it will not be appropriate in every situation. Serious allegations, safeguarding concerns or matters requiring formal investigation may need to be dealt with through a different process.
The manager's role is to support an appropriate process rather than take sides or attempt to decide who is right. Following mediation, managers should support any agreed actions, monitor the working relationship and address further concerns promptly.

Mediation is a structured process in which an impartial person helps people involved in a workplace dispute or conflict discuss the issues and work towards an agreed way forward.
Mediation may be appropriate where employees have an ongoing working relationship, there is a disagreement or breakdown in communication and those involved are willing to work towards resolving the situation.
Mediation is normally voluntary. Employees should understand the purpose of the process and agree to participate. Managers should speak to HR if they are considering mediation in a particular situation.
A manager may be able to facilitate an informal conversation in appropriate circumstances, but formal mediation is generally better handled by someone impartial and suitably trained, particularly where the manager is responsible for managing one or both employees.
Mediation may not be appropriate where there are serious allegations of misconduct, safeguarding concerns, significant power imbalances, an unwillingness to participate or circumstances where a formal investigation is required.
No. Mediation is an alternative way of attempting to resolve some workplace issues and does not remove an employee's right to raise a formal grievance. HR should advise on the most appropriate process.
The parties may agree practical steps for improving the working relationship. Managers should support those arrangements and follow up appropriately. If the conflict continues, further HR advice may be required.
