Do you have to give notice for an investigation meeting?
ACAS guidance says an employer needs to give reasonable notice of an investigation meeting and explain its purpose. There is no universal statutory rule requiring 24 hours, 48 hours or five days for every investigation interview. The notice needs to be assessed against the subject, preparation required and applicable policy.
Check what kind of meeting this is
An investigation gathers information. A disciplinary hearing considers allegations and possible disciplinary action. The invitation’s title is useful, but ask what decisions the meeting can make. A meeting described as informal needs clarification if the employer intends to issue a warning.
Also establish your role. Being interviewed as a witness is different from answering an allegation about your own conduct. The information needed to prepare will differ.
What makes notice reasonable?
Identify the work required before attending. You may need to read the invitation, locate a particular record, understand a date or arrange an adjustment. A short meeting about a recent event differs from an interview covering months of transactions.
Check for a notice period in the investigation or disciplinary policy. If the invitation does not follow it, identify the provision and ask for an explanation. Avoid stating a fixed legal entitlement which the policy or law does not provide.
Requesting more time
Explain the specific reason for an extension and propose an alternative date. For example, identify the documents the employer has not provided or an adjustment you need. Link the request to your ability to give an accurate account.
If the employer declines, keep its response. Confirm any limitations on what you can answer and ask to provide a further written response after receiving the missing information. Do not silently miss the meeting or assume a request has been agreed.
Can someone attend with you?
A disciplinary investigation interview normally has no statutory right to a companion. A policy may provide more, and reasonable adjustments may be relevant for a disabled employee. A formal disciplinary hearing and qualifying grievance meetings carry different accompaniment rights.
Ask for the arrangement you need and explain its basis. Do not assume the right to a companion includes a solicitor in every workplace meeting.
Why the first interview matters
An investigator may use the interview notes when deciding which evidence to collect and which matters remain disputed. If your answer depends on a record you have not seen, say so. Distinguish what you recall from what you need to check.
Request the notes and raise inaccuracies with the relevant correction. A precise correction is more useful than stating the entire account is wrong without identifying the disputed wording.
Questions employees ask
Is a same day invitation always unlawful? No. Its fairness depends on the circumstances. Explain the preparation problem rather than relying only on the number of hours.
Does the five working day companion rule apply here? Do not apply the statutory disciplinary hearing postponement rule automatically to an investigation interview. First establish the type of meeting and applicable right.
Get advice before the interview
An incomplete or inaccurate first account can affect the investigation report. A Belonge Case Assessment reviews the invitation, allegations, relevant policy and supporting records. The £149, one hour assessment includes a written report with findings and recommended actions.
