Investigation Meeting vs Disciplinary Hearing: What's the Difference?
A practical guide for UK managers
A Practical Guide for UK Managers
Investigation meetings and disciplinary hearings are often spoken about as though they're interchangeable. They're not.
They have different purposes, happen at different stages of a disciplinary process and, most importantly, should involve a different mindset from the manager conducting them.
The simplest distinction is this:
An investigation meeting is about establishing the facts.
A disciplinary hearing is about considering the case and deciding what should happen.
Getting those two stages confused can undermine an otherwise reasonable disciplinary process.
WHAT IS AN INVESTIGATION MEETING?
An investigation meeting is part of the fact-finding stage.
At this point, the business should not have decided that the employee has committed misconduct.
The purpose of the meeting is to understand what happened.
That could mean speaking to:
The employee whose conduct is being investigated
The person who raised the concern
Witnesses
Other people who may hold relevant information
The investigator may also need to consider documents, CCTV, emails, messages, system records or other evidence.
The key word is: Investigate. The manager should be trying to establish the facts rather than prove an allegation.
WHAT SHOULD HAPPEN DURING AN INVESTIGATION MEEETING?
The investigator should explain what is being investigated and give the employee an opportunity to provide their account. Questions should generally begin openly.
For example:
“Talk me through what happened during your conversation with your manager on Monday.”
The investigator can then explore the detail.
If something doesn't make sense, it is entirely appropriate to challenge it. If the employee's account contradicts CCTV, witness evidence or another document, ask them about that contradiction. Being impartial doesn't mean avoiding difficult questions. It means asking those questions because you're trying to understand what happened rather than trying to prove the employee guilty.
HR UNFILTERED TAKE
A good investigation meeting should create more clarity, not deliver an outcome. If the manager enters the room already thinking about which warning they're going to issue, they've skipped an important part of the process.
WHAT HAPPENED AFTER THE INVESTIGATION?
Once the necessary investigation has been completed, the evidence needs to be considered.
The question at this stage is usually: Is there a case to answer? There are broadly two possibilities.
There isn't a case to answer
The evidence may not support the allegation or there may not be sufficient reason to take the matter into a formal disciplinary process. That doesn't mean the investigation failed. It means the investigation did what it was supposed to do.
There is a case to answer
If the investigation identifies sufficient grounds for the matter to be considered formally, the employee can be invited to a disciplinary hearing. And that's where the purpose of the process changes.
WHAT IS A DISCIPLINARY HEARING?
A disciplinary hearing is the formal meeting where the allegations and evidence are considered before a disciplinary decision is made. The employee should know what they're alleged to have done and have access to the relevant evidence being relied upon, with reasonable time to prepare.
The hearing gives them an opportunity to:
Respond to the allegations
Explain their position
Challenge the evidence
Provide their own evidence
Raise relevant mitigating circumstances
Ask questions
Respond to relevant witness information
Only after that process should the decision-maker determine the appropriate outcome. The difference in one example. Imagine a manager receives an allegation that an employee became aggressive towards a colleague and swore at them during an argument.
At the investigation meeting:
The investigator might ask:
“Talk me through what happened.”
“What was said during the conversation?”
“Who else was present?”
“How would you describe your behaviour?”
“Did you use any inappropriate language?”
“Is there anything else you think I should consider?”
The purpose is to establish the employee's account and identify what other evidence needs to be considered.
At the disciplinary hearing, the allegation might now be presented clearly:
“It is alleged that during an interaction with a colleague on 18 August, you used abusive and inappropriate language and behaved in an aggressive manner.”
The hearing manager can then consider the investigation evidence and ask the employee to respond. They may explore:
“The investigation identified two witnesses who both recall you using the same phrase. What is your response to that evidence?”
“You've accepted that you raised your voice. Can you explain what was happening at the time?”
“Is there anything you believe I should take into consideration when reaching my decision?”
The distinction is important. During the investigation you're trying to establish what happened. During the disciplinary hearing you're considering whether the allegation is substantiated and, if so, what the appropriate outcome should be.
DOES THE EMPLOYEE HAVE THE RIGHT TO BE ACCOMPANIED?
This is another important difference. At a disciplinary hearing, employees have a statutory right to make a reasonable request to be accompanied by an eligible companion. At a investigation meeting, there is not generally the same statutory right to be accompanied. However, an organisation's own policy may provide a right to accompaniment at investigation meetings, and allowing a companion can also be good practice. There may also be circumstances where an employer needs to consider reasonable adjustments or another appropriate form of support. So before refusing a request for someone to attend an investigation meeting, check your own procedure and consider the circumstances rather than relying solely on the absence of a general statutory right.
SHOULD THE INVESTIGATOR CHAIR THE DISCIPLINARY HEARING?
Where practicable, no. Separating the roles helps maintain objectivity. The investigator has spent time gathering evidence, interviewing witnesses and potentially reaching conclusions about whether there is a case to answer. A separate hearing manager can approach the disciplinary stage with a different responsibility:
Consider the evidence, listen to the employee's response and make the decision.
In smaller businesses, completely separating every stage may not always be practical. Where that happens, the business should still make every reasonable effort to ensure the process remains impartial.
CAN YOU ISSUE A WARNING DURING AN INVESTIGATION MEETING?
An investigation meeting should not itself result in disciplinary action. If the investigation identifies a case to answer, move to the disciplinary stage properly. That means giving the employee appropriate written notification of the disciplinary hearing, explaining the allegation, providing the relevant evidence and allowing reasonable time to prepare. Don't turn an investigation meeting into a disciplinary hearing halfway through because you've heard enough to make up your mind.
HR UNFILTERED TAKE
Process doesn't need to be complicated, but the stages need to mean something. Calling a meeting an “investigation” while questioning the employee as though they're already guilty, and then delivering a warning isn't a shortcut. It's muddling fact finding and decision making together.
INVESTIGATION MEETING VS DISCIPLINARY HEARING.
COMMON MISTAKES MANAGERS MAKE
The most common problems aren't usually complicated procedural errors.
They're things like:
Referring to the employee as “guilty” during the investigation
Writing investigation questions designed to prove the allegation
Deciding the sanction before the disciplinary hearing
Giving a warning at the end of an investigation meeting
Failing to explain clearly when the process has moved from investigation to disciplinary
Not providing the employee with the relevant evidence before the hearing
Giving insufficient time to prepare
Assuming an investigation meeting and disciplinary hearing can simply be combined
Ignoring the organisation's own disciplinary procedure
Treating “case to answer” as though it means “guilty”
That last one is particularly important. A case to answer is not a finding of guilt. It simply means there is sufficient reason for the allegation to be considered at the next stage.
The bottom line If you're managing a disciplinary process, keep the purpose of each stage clear.
Investigation: What happened?
Decision following investigation: Is there a case to answer?
Disciplinary hearing: Having considered the allegation, evidence and employee's response, is the allegation substantiated?
Outcome: If it is substantiated, what is the reasonable and appropriate action?
Keeping those questions separate creates a much clearer process for the manager and a fairer process for the employee, and it makes the reasoning behind the eventual decision considerably easier to demonstrate.
