Witnesses can provide important evidence during a workplace investigation, particularly where the facts of an incident are disputed or information needs to be obtained from someone who was present or has relevant knowledge. This letter provides a professional invitation to a witness and explains what their involvement in the investigation will involve.
The letter gives the employee a brief explanation of the matter being investigated and why their evidence may be relevant. It should provide enough context for them to understand the purpose of the meeting without unnecessarily disclosing confidential information about other employees.
The investigation meeting should give the witness an opportunity to describe what they personally saw, heard or know about the matter. The investigator can use open questions to establish facts and identify any documents, communications or other witnesses that may be relevant.
Investigations can involve sensitive information about colleagues. The letter can set appropriate expectations around confidentiality while making clear that the witness should provide an honest account and should not be pressured to give a particular version of events.
Witness evidence should be considered alongside all other relevant information rather than automatically treated as conclusive. A properly documented witness meeting helps the investigator build an accurate evidence base before deciding whether further investigation or formal action is appropriate.

Understand the common mistakes to avoid when using this HR template, helping you reduce risk, prevent unnecessary costs and ensure the process is handled correctly.
Employees should normally cooperate with a reasonable workplace investigation where they have relevant information. If a witness cannot attend, the employer should consider the reason and whether the meeting can be rearranged or an alternative way of obtaining their evidence can be used.
There is generally no statutory right to be accompanied at a witness interview. However, an employer's policy may provide for accompaniment and reasonable adjustments may also be appropriate depending on the circumstances.
The witness should receive enough information to understand why they are being invited and what they are being asked to discuss. However, the employer should avoid disclosing unnecessary confidential information about the allegation, the person involved or other witnesses.
This will depend on the organisation's investigation process and the circumstances. If a written statement is taken, the employer should ensure that it accurately reflects the witness's evidence and handle it in accordance with its confidentiality and data protection arrangements.
An employee should normally cooperate with a reasonable investigation, but there may be circumstances where they have a legitimate concern about providing particular information. The investigator should consider the reason, explain the purpose of the question and seek HR advice where necessary.
AI can produce a generic witness invitation, but it may disclose too much information, use leading language or fail to distinguish a witness meeting from the investigation of the employee who is the subject of the allegation.
