Workplace Investigations
Contributing Editors
Workplace investigations are growing in number, size and complexity. Employers are under greater scrutiny as of the importance of ESG rises. Regulated industries such as finance, healthcare and legal face additional hurdles, but public scrutiny of businesses and how they treat their people across the board has never been higher. Conducting a fair and thorough workplace investigation is therefore critical to the optimal operation, governance and legal exposure of every business.
IEL’s Guide to Workplace Investigations examines key issues that organisations need to consider as they initiate, conduct and conclude investigations in 29 major jurisdictions around the world.

Workplace investigations should usually be conducted on a confidential basis, so that only those involved in the investigation are aware of its existence and subject matter. The need to maintain confidentiality about both the fact of the investigation, and any content discussed with an investigator, should be emphasised to all those involved. It may also be necessary to explain that a breach of confidentiality could be viewed as a disciplinary matter. Appropriate exceptions must, however, be made to allow employees to speak to any relevant employee or trade union representative, legal adviser and potentially the police or other regulators. Confidentiality provisions cannot override the rights of workers to make protected disclosures (see question 9).
In some situations, such as those involving a wide-ranging investigation into the organisation’s working practices and culture, it may be more appropriate to investigate a more “open” basis, and inform employees and other stakeholders.

A reasonable investigation is a key component of a fair disciplinary process. Errors in the investigation could therefore expose the employer to liability for unfair dismissal under ERA 1996.
Failure to follow the ACAS Code does not automatically make an employer liable in any proceedings taken against it. However, an employment tribunal will take the ACAS Code into account when deciding whether an employer has behaved fairly, and has the power to increase awards by up to 25% where it believes an employer has unreasonably failed to follow the ACAS Code's provisions.
There may be liability for breach of the employee’s contract of employment if the employer breaches aspects of the investigation policy that are contractual, any contractual provisions relating to suspension, or otherwise conducts the investigation in a manner that breaches the implied term of trust and confidence.
There may be liability under the EA 2010 if the investigation is conducted in a discriminatory manner, which could include not making reasonable adjustments to the process for disabled employees.
Where the investigation involves protected disclosures, there may be liability under the whistleblowing provisions of ERA 1996 if the whistleblower is subjected to detriment or dismissal on the grounds of their protected disclosures.
Improper evidence gathering or processing may be actionable under the DPA 2018, IPA 2016 or the IP Regs 2018.
Finally, there may be common law claims in some circumstances (for example where reports need to be made to regulators, which in turn may affect the relevant employee’s future employment prospects) for defamation, or, more unusually, for stress-related personal injury.
