Informal Investigation Meetings at Work: UK Employer Requirements

If you run a small business, workplace issues can land on your desk fast - a complaint about conduct, a rumour of bullying, a suspected policy breach, or a performance concern that’s starting to affect the team.

Before you jump straight to “formal disciplinary”, you’ll often need to gather the facts first. That’s where an informal investigation meeting at work can come in.

Used properly, an informal investigation meeting can help you understand what’s happened, reduce misunderstandings, and decide the fairest next step (which might be no further action at all). Used poorly, it can blur into a disciplinary process without the right safeguards - and that’s when problems start.

Below, we’ll walk you through what an informal investigation meeting is, when to use one, how to run it fairly, what to document, and the common pitfalls UK employers should avoid.

What Is An Informal Investigation Meeting At Work?

An informal investigation meeting at work is a meeting you hold to gather information about a concern or allegation before deciding whether a formal process is needed.

In plain terms: it’s a fact-finding meeting, not a disciplinary hearing.

Typically, you’re using the meeting to:

• clarify what the concern actually is (and whether it’s serious or credible);
• understand who was involved and what happened (as far as you can tell at this stage);
• identify what evidence exists (messages, CCTV, rotas, emails, records);
• consider whether immediate steps are needed (e.g. temporary change of duties or reporting lines); and
• decide whether to move to a formal investigation or disciplinary process.

Even if you’re keeping it “informal”, you still need to keep things fair and consistent. Many disputes don’t start because an employer investigated - they start because the process felt unfair, rushed, or pre-judged.

If you want to run a more structured information-gathering session, the same principles usually apply as a fact-finding meeting, just with a lighter-touch approach where appropriate.

When Should You Use An Informal Investigation Meeting (And When Should You Go Straight To Formal)?

For small businesses, the “right” process depends on the context - your team size, the seriousness of the issue, and the risk to people and the business.

Common Situations Where An Informal Investigation Meeting Makes Sense

An informal investigation meeting at work is often suitable where:

• the concern is low to medium seriousness (e.g. a misunderstanding, minor misconduct, early-stage conflict);
• you need to clarify what happened because the details are unclear or conflicting;
• you’ve received an informal complaint and want to understand whether the person wants a formal grievance;
• performance concerns have been raised but you’re still diagnosing what’s driving them (skills, workload, conduct, personal issues); or
• you want to explore whether the issue can be resolved quickly and proportionately without escalating.

For performance issues, this step can feed into whether you move to a more formal support process like Performance Improvement Plans or another capability route.

When You Should Consider A More Formal Approach Immediately

In some situations, going “informal” can actually create risk, especially if the allegation is serious. You may need a more formal investigation process from the outset if:

• there are allegations that could amount to gross misconduct (e.g. violence, theft, serious harassment, major data breach);
• there’s a safeguarding concern or a risk to health and safety;
• the complaint relates to a protected characteristic (e.g. discrimination) and requires careful handling;
• there’s a risk evidence could be destroyed or influenced; or
• you may need to consider suspension (even then, suspension should not be a “default” response).

If the issue is potentially gross misconduct, it’s worth aligning your internal handling with a clear gross misconduct checklist so you don’t accidentally treat a high-risk matter too casually.

How To Run An Informal Investigation Meeting Fairly (A Practical Step-By-Step)

Even an informal process should be planned. The goal is to gather facts without turning the meeting into a disciplinary hearing.

1) Be Clear About The Meeting’s Purpose

When you invite the employee, tell them clearly that:

• the meeting is to understand what has happened;
• no decisions have been made; and
• it’s not a disciplinary hearing (unless you’re explicitly moving to that stage).

This matters because employees can feel ambushed if the meeting sounds “informal” but the questioning feels accusatory. That’s where mistrust begins.

2) Give Reasonable Notice And Basic Information

There’s no single “magic number” of days for an informal investigation meeting at work, but as a rule of thumb:

• give enough notice for the employee to attend without undue stress (and to recall events);
• share a short summary of the concern, so they understand what the meeting is about; and
• tell them who will be in the meeting.

If you already have a staff policy that deals with investigations and disciplinary steps, follow it consistently. If you don’t have one, that’s often a sign it’s time to put a proper process into your team documents (many small businesses build this into a handbook alongside their Employment Contract terms).

3) Choose The Right Person To Lead The Meeting

Ideally, the meeting should be led by someone:

• who is reasonably neutral (not personally involved in the incident);
• who can stay calm and professional; and
• who understands your policies and expectations.

In a small business, this might be the owner or a manager. If the issue involves that person, consider whether someone else can lead, or whether you need external HR/legal support.

4) Use Open Questions (And Avoid Cross-Examination)

You’re not trying to “win” the meeting - you’re trying to understand what happened.

Useful question styles include:

• Open questions: “Can you talk me through what happened from your perspective?”
• Clarifying questions: “When you say ‘he raised his voice’, what do you mean?”
• Timeline questions: “What happened just before that?” / “What happened after?”
• Evidence questions: “Were there any messages or emails about this?”
• Impact questions: “How has this affected your work or the team?”

Avoid loaded questions like “Why did you do it?” (which assumes wrongdoing). Instead, try: “Help me understand what led to that decision.”

5) Keep The Meeting Notes Accurate (And Store Them Securely)

Take notes during the meeting (or shortly after) covering:

• date, time, and attendees;
• what was discussed;
• any key factual points agreed or disputed;
• any documents referenced; and
• next steps (including who is doing what, and by when).

Remember: notes can become important later - for example, if you later move to a disciplinary, a grievance, or (in worst-case scenarios) an Employment Tribunal claim.

Also, meeting notes will often contain personal data. Make sure you store them securely and only share them on a need-to-know basis.

6) Decide Next Steps Promptly And Communicate Them

At the end of the informal investigation meeting at work, you don’t need to decide immediately - but you should explain what will happen next.

Next steps could include:

• no further action (for example, where the concern is unsubstantiated);
• informal management action (coaching, mediation, clarifying expectations);
• a formal investigation (including interviewing other witnesses);
• starting a capability/performance route; or
• moving to disciplinary (where appropriate and fair).

If the matter does become formal, make sure your meeting invitations and documentation are clearly written and consistent. For example, if you’re inviting someone to a formal stage, you’ll want to do it properly, similar to how you would invite employees to a disciplinary meeting.

Do Employees Have The Right To Bring Someone To An Informal Investigation Meeting?

This is a common question for employers, especially small businesses trying to keep processes simple and calm.

In the UK, the statutory right to be accompanied (for example, by a trade union representative or colleague) generally applies to certain formal disciplinary and grievance hearings.

It does not usually apply to investigatory or fact-finding meetings, including an informal investigation meeting at work. However, your own policies or contracts may give a wider right, and you should also consider whether allowing a companion is needed as a reasonable adjustment (for example, for a disability) or otherwise to keep the process fair.

In practice, many employers choose to allow a companion where:

• the employee is particularly anxious or vulnerable;
• the allegation is serious and could lead to a formal process;
• there’s a language barrier or a reasonable adjustment is needed; or
• your internal policies allow it.

That said, you’ll also want to keep the meeting manageable and avoid it becoming adversarial. A good middle-ground approach is:

• explain that it’s an information-gathering meeting, not a hearing;
• allow a support person where it’s reasonable; and
• set expectations that the employee should answer questions themselves.

If you’re unsure, it’s worth getting advice upfront - especially where the outcome could later involve disciplinary action or dismissal.

Common Mistakes Employers Make (And How To Avoid Them)

Most employers don’t get workplace investigations “wrong” because they don’t care. It’s usually because they’re moving fast, trying to protect the business, and juggling limited time and resources.

Here are some common pitfalls we see with informal investigation meetings at work.

Treating The Meeting Like A Disciplinary Hearing

If you approach the conversation as if the employee is already guilty, you can undermine the fairness of your whole process.

Keep your language neutral, focus on facts, and avoid making conclusions in the meeting.

Not Following Your Own Policies

If your handbook says you’ll do X, but you do Y, you can end up with consistency and fairness issues. This is particularly risky if different employees are treated differently for similar conduct.

Rushing To Suspension Without Good Reason

Suspension can be appropriate in some cases, but it should usually be a last resort and handled carefully.

If suspension is on the table, make sure you understand the risks and best practice around employee suspension - because a poorly handled suspension can create its own legal and employee relations issues.

Failing To Keep Records

Even if the meeting is “informal”, you need a reliable record of what was discussed and what you decided. Without notes, you may later struggle to show your decisions were reasonable and fair.

Blurring A Performance Issue With Misconduct

Sometimes a problem looks like misconduct (e.g. missed deadlines), but it’s actually capability, training, workload, or unclear expectations.

If you jump to discipline when the issue is capability, you increase the risk of an unfair outcome and damaging trust.

Letting The Issue Drift

If you hold an informal investigation meeting at work and then do nothing for weeks, employees can lose confidence in you, memories fade, and evidence disappears.

Set timelines and keep the process moving.

Key Takeaways

• An informal investigation meeting at work is a fact-finding conversation to understand an issue before deciding whether formal steps are needed.
• Even “informal” meetings should be handled fairly: be clear about the purpose, use neutral questions, keep accurate notes, and communicate next steps.
• Consider moving straight to a more formal process where allegations are serious, involve potential gross misconduct, or raise safety or discrimination risks.
• Be consistent with your policies and avoid treating the meeting like a disciplinary hearing - jumping to conclusions early can create legal and practical problems later.
• Keep records securely, as notes from an informal investigation meeting can become important evidence if the matter escalates.
• If you’re unsure whether to allow a companion, whether suspension is appropriate, or how to progress to disciplinary fairly, get advice early to protect your business.
