Protected Conversations vs Without Prejudice: What's the Difference?

When a workplace issue becomes difficult, employers often hear the terms protected conversation and without prejudice used interchangeably.

While both relate to confidential discussions, they are not the same thing, and using the wrong approach can leave employers exposed if a dispute later reaches an Employment Tribunal.

Understanding the difference is important, particularly when discussing sensitive issues such as performance concerns, capability, ill health, organisational change or the possibility of ending employment by mutual agreement.

What Is a Protected Conversation?

A protected conversation is a discussion between an employer and an employee about ending employment on agreed terms. Under section 111A of the Employment Rights Act 1996, these conversations are generally inadmissible in an ordinary unfair dismissal claim, meaning they cannot usually be referred to in an Employment Tribunal.

This allows employers and employees to have an open conversation about a potential settlement agreement without worrying that simply raising the idea will automatically be used against them later.

For example, an employer may decide that a working relationship has broken down, or that a capability process is unlikely to result in improvement. Rather than continuing through a lengthy formal process, they may explore whether the employee would be interested in leaving under a settlement agreement. Importantly, there does not need to be an existing dispute for a protected conversation to take place.

What Is Without Prejudice?

Without prejudice is a long-established legal principle that protects genuine attempts to settle an existing dispute. Unlike protected conversations, there must already be a dispute between the parties before without prejudice discussions can apply.

For example, if an employee has raised a grievance alleging discrimination, or they have indicated they intend to bring legal proceedings, discussions aimed at resolving that dispute may be be protected under the without prejudice principle.

The purpose is to encourage honest settlement negotiations without either side worrying that their offers or concessions will later be used as evidence.

The Key Differences

The biggest distinction is simple:

Protected Conversations:

• No existing dispute is required

• Specifically relates to discussions about ending employment on agreed terms

• Protected under section 111A of the Employment Rights Act 1996

• Usually applies only to ordinary unfair dismissal claims

• Protection can be lost through improper behaviour

Without Prejudice:

• A genuine dispute must already exist

• Applies to genuine attempts to settle an existing dispute

• Protected under common law

• Can apply more widely across different legal claims where the conditions are met

• Protection may not apply if there is no genuine dispute or in limited exceptional circumstances

Because of this, many employers wrongly assume that simply marking an email "Without Prejudice" makes it confidential. It does not. If no dispute exists, the protection may not apply at all.

Can Both Apply at the Same Time?

Yes. In some situations, both protections may be available. For example, an employee may already be in a formal dispute with their employer and the parties decide to discuss a settlement agreement. Depending on the circumstances, both the protected conversation rules and the without prejudice principle may apply. However, this should not be assumed. The legal position depends on the facts of each case.

Can You Say "Without Prejudice" in Every Email?

No. A common misconception is that simply writing "Without Prejudice" at the top of a letter or email automatically makes it confidential. It does not.

Whether the protection applies depends on the circumstances, not the heading on the document. If there is no genuine dispute between the employer and employee, the without prejudice principle is unlikely to apply, regardless of what the correspondence is labelled.

This is why employers should be cautious about relying on the phrase without understanding the legal requirements behind it.

Are Protected Conversations Always Protected?

No. There are important exceptions. Protection can be lost if there has been improper behaviour during the discussion. Examples may include:

• Bullying or intimidation.

• Harassment or discrimination.

• Victimisation.

• Undue pressure to accept an offer.

• Threats of dismissal if the employee refuses to sign immediately.

• Misleading or dishonest behaviour.

ACAS recommends employees should normally be given at least 10 calendar days to consider a written settlement agreement, unless the parties agree otherwise. If an employer behaves inappropriately, an Employment Tribunal may allow evidence of the conversation to be considered.

Are Without Prejudice Conversations Always Protected?

Again, no. Without prejudice protection is not absolute. For example, it may not apply where there is evidence of fraud, misrepresentation, undue influence or other forms of serious improper conduct.

It also cannot be relied upon if there was never a genuine dispute in the first place. Simply writing "Without Prejudice" at the top of a letter or email does not automatically make it privileged.

Common Mistakes Employers Make

Some of the most common misunderstandings include:

• Assuming protected conversations and without prejudice mean the same thing.

• Labelling correspondence "Without Prejudice" when there is no dispute.

• Beginning settlement discussions without planning how the conversation will be managed.

• Putting undue pressure on employees to make a quick decision.

• Assuming everything said will automatically remain confidential.

• Failing to obtain legal advice when drafting a settlement agreement.

Understanding which legal principle applies can make a significant difference if matters later end up before an Employment Tribunal.

Which One Should Employers Use?

It depends on the circumstances. If there is no existing dispute, but you want to explore whether an employee may be willing to leave under a settlement agreement, a protected conversation is often the appropriate route.

If there is already an active dispute and both parties are trying to reach a resolution, discussions may fall under the without prejudice principle. Every situation is different, and employers should consider the wider employment law implications before beginning either type of discussion.

Need HR Support?

Protected conversations and without prejudice discussions both exist to encourage frank conversations and help resolve workplace issues, but they operate in different circumstances and have different legal requirements. Using the wrong approach, or assuming a conversation is automatically protected, can create unnecessary risk for employers.
