What is a Workplace Investigation?

The purpose of an investigation is to collect all the relevant information and evidence relating to an alleged misconduct.

Making decisions on a workplace disciplinary or grievance without reasonably completing a fact-finding exercise may render any subsequent decisions or actions taken unfair or unlawful, which can expose the organisation to the risk of legal action.

Undertaking an investigation will often be required as part of a disciplinary or grievance process. In order to ensure that the investigation was fair and appropriate it is good practice to plan, record and invite correctly.

Investigation templates are essential for managing a low-risk, compliant Investigation process.

How Should a Workplace Investigation Be Carried Out?

A workplace investigation provides a structured way to establish the facts when concerns or allegations arise. It will typically follow these key stages:

1
Issue A concern, allegation or incident requiring investigation is identified.
2
Plan The investigator identifies the issues, evidence and people who may need to be contacted.
3
Investigate Relevant evidence and accounts are gathered objectively.
4
Findings The available evidence is assessed and findings are recorded.
5
Next step The findings inform whether further action is appropriate.

An investigation is fact-finding. The investigator should remain open-minded and consider evidence that supports different explanations.

UK employment law and best practice

This toolkit is designed to support Investigation, but its resources should be used alongside the relevant HR policies and procedures and applied to the circumstances of each individual case. Always consider the specific facts, your organisation's processes and the applicable employment law before taking action.

Workplace investigations should be fair, objective and proportionate to the issue being investigated. The documents in this toolkit are designed to support investigation planning and evidence gathering and should be used alongside the relevant HR procedure.

Purpose of an investigation

An investigation should establish the relevant facts rather than assume that an allegation is proven. Investigators should approach the matter objectively and consider evidence that supports and contradicts the allegation. https://www.acas.org.uk/acas-code-of-practice-on-disciplinary-and-grievance-procedures

Evidence and witnesses

Employers should gather relevant documents and speak to appropriate witnesses. Investigation records should distinguish factual evidence from opinion or assumptions.

Impartiality

Wherever possible, the investigator should not have a conflict of interest or personal involvement in the matter. More serious cases may require an appropriately independent investigator.

Confidentiality and data protection

Investigation information should be shared only with those who need it for legitimate purposes. Personal information should be handled in accordance with data protection requirements. https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/employment/

FAQs

What is a workplace investigation?

A workplace investigation is a structured process for establishing facts and gathering relevant evidence about an issue or allegation at work.

When should an employer investigate?

An investigation may be appropriate where an allegation or concern requires facts to be established before the employer decides what action, if any, should follow.

Who should conduct an investigation?

The investigator should be sufficiently impartial, appropriately skilled and independent of the issue where possible. The choice will depend on the circumstances.

What evidence should an investigation consider?

Evidence may include documents, emails, records, witness accounts, CCTV, system information and other relevant material, depending on the issue being investigated.

Should an investigation be documented?

Yes. Appropriate investigation records should show what was considered, who was interviewed, what evidence was reviewed and the findings reached.
