Without Prejudice: What It Really Means at Work

Written by: Owen John, Employment Law Partner, Darwin Gray | Last updated: 24/10/2026 | Reviewed by: Owen John

Key takeaways

• “Without prejudice” protects genuine attempts to settle a dispute from being used as evidence later.
• It only applies when there’s an existing dispute and the discussion is a real effort to resolve it. The label alone doesn’t make it stick.
• If it applies, what’s said in a without prejudice conversation or letter generally can’t be shown to a tribunal.
• It’s different from a protected conversation, which can apply even when there’s no dispute yet.
• Labelling something “without prejudice” when it shouldn’t be, or leaving it off when it should be there, are both common and costly mistakes.

What does “without prejudice” mean?

“Without prejudice” is a legal rule that lets two sides in a dispute talk openly about settling, without worrying that what they say will be quoted against them if the matter ends up at a tribunal or in court. The idea is simple and sensible: people settle disputes more easily if they can speak frankly, make offers, and even make concessions, without those words coming back to bite them.

So if your employer writes to you “without prejudice” proposing a settlement, or has a without prejudice conversation with you about leaving, the point is that neither of you can later wave that around as evidence. It keeps settlement talk off the record.

You’ll see it a lot around settlement agreements, often in the same breath as a protected conversation. They overlap, but they’re not the same thing, and the difference matters.

When does “without prejudice” actually apply?

Here’s the part people get wrong. Writing “without prejudice” at the top of an email doesn’t automatically make it protected. For the rule to apply, two things generally need to be true:

1. There’s an existing dispute between you and your employer. That doesn’t mean you’re already at a tribunal, but there needs to be a genuine disagreement that could end up in a legal claim.
2. The communication is a genuine attempt to settle that dispute. An offer, a negotiation, a concession, something aimed at resolving things.

If both boxes are ticked, the conversation or letter is protected whether or not anyone said the magic words. If they’re not ticked, slapping “without prejudice” on it changes nothing. The substance matters more than the label.

Can a without prejudice conversation be used against me?

If the rule properly applies, then no, the conversation generally can’t be put in front of a tribunal as evidence. That protection cuts both ways: your employer can’t use your words against you, and you can’t use theirs against them.

There are exceptions. The protection can fall away where, for example, there’s been “unambiguous impropriety”, something seriously improper said during the discussion, like blackmail or outright discrimination dressed up as a settlement chat. These exceptions are narrow and don’t apply just because you didn’t like how the conversation went. If you think something said to you crosses a line, that’s exactly the kind of thing to get advice on, because it affects whether the conversation can be used at all.

Without prejudice vs protected conversation

This is the distinction worth holding onto:

• Without prejudice needs an existing dispute. It protects genuine settlement discussions about that dispute.
• Protected conversation (under section 111A of the Employment Rights Act) can apply even where there’s no dispute yet, but only for ordinary unfair dismissal claims, and the protection is narrower.

In practice, employers often rely on both at once when they open settlement discussions, because each covers a gap the other leaves. If you’ve been approached about a settlement and you’re not sure what’s protected and what isn’t, we can untangle it for you.

“Without prejudice save as to costs”

You might see a longer version: “without prejudice save as to costs”. This means the communication stays off the record for the main dispute, but can be shown to a tribunal or court later when it’s deciding who pays the costs. It’s a way of saying “we tried to settle reasonably, and the other side wouldn’t”, once the outcome is known. It mostly matters in litigation, but it’s worth recognising if you see it.

Why this matters for your settlement

If your employer opens a conversation “without prejudice” and offers you a settlement agreement, understanding what’s protected shapes how you respond. It affects what you can safely say, what leverage you have, and whether anything that’s happened gives you grounds to push back. We’ll walk you through exactly what you can and can’t rely on, and make sure you don’t give anything away you didn’t mean to.

Frequently asked questions

Does writing “without prejudice” on a letter make it protected?

Not on its own. The label only works if there’s a genuine existing dispute and the letter is a real attempt to settle it. If those conditions aren’t met, the words “without prejudice” have no effect, and the letter can be treated like any other. The reverse is also true: a genuine settlement communication can be protected even if nobody wrote “without prejudice” on it. The substance matters more than the heading.

Can my employer use a without prejudice conversation against me at a tribunal?

If the without prejudice rule properly applies, generally no, neither side can put that conversation in front of a tribunal. The protection is mutual. There are narrow exceptions, mainly where something seriously improper was said (known as “unambiguous impropriety”). Those exceptions don’t apply just because the conversation was uncomfortable. If you think something said to you was improper, get advice, because it affects whether the conversation stays protected.

What’s the difference between without prejudice and a protected conversation?

Without prejudice needs an existing dispute and protects genuine settlement talks about it. A protected conversation (section 111A) can apply even when there’s no dispute, but only covers ordinary unfair dismissal claims and has narrower protection. Employers often rely on both when opening settlement discussions. The practical upshot is that what’s protected depends on the situation, which is worth clarifying before you respond to any offer.

My employer wants a “without prejudice chat”. Should I be worried?

It usually means they want to discuss you leaving on agreed terms, often with a settlement agreement. It’s not something to panic about, but it is something to take seriously and get advice on before you say much. You don’t have to respond on the spot. You can listen, say you’ll take advice, and come back. That’s a completely normal and sensible response, and it keeps your options open.
