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.

In Ireland, employees have a constitutional right and an implied contractual right to natural justice and fair procedures. If a workplace investigation is not conducted in accordance with these principles, an employee may allege that the investigation is fundamentally flawed. If such an allegation is made then an employee may seek recourse from the Workplace Relations Commission (WRC) or potentially the High Court. The WRC is the body in Ireland tasked with dealing with employment law-related claims, including unfair dismissal.
The constitutional rights that employees enjoy were specified in the Supreme Court case of Re Haughey in 1971. That case held that where proceedings may harm the reputation of a person, public bodies must afford certain basic protections of constitutional justice to a witness appearing before it. It further stated that article 40.3 of the Irish Constitution is a guarantee to the citizen of basic fairness of procedures. These protections, known as “Re Haughey rights” are implied in each contract of employment.
A Code of Practice was introduced in 2000, namely S.I. No. 146/2000 - Industrial Relations Act, 1990 (Code of Practice on Grievance and Disciplinary Procedures) (Declaration) Order, 2000 (the Code). The Code set out the procedures for dealing with grievances or disciplinary matters, which must comply with the general principles of natural justice and fair procedures and include:
- that employee grievances are fairly examined and processed;
- that details of any allegations or complaints are put to the employee concerned;
- that the employee concerned is allowed to respond fully to any such allegations or complaints;
- that the employee concerned is given the opportunity to avail of the right to be represented during the procedure; and
- that the employee concerned has the right to a fair and impartial determination of the issues concerned, taking into account any representations made by, or on behalf of, the employee and any other relevant or appropriate evidence, factors or circumstances.
Further Codes of Practice on the prevention and resolution of bullying at work and on dealing with sexual harassment and harassment at work were published in 2021 and 2022, respectively. The provisions of these codes are admissible in evidence before a court, the WRC and the Labour Court.
In addition to the above, the Data Protection Commission published Data Protection in the Workplace: Employer Guidance in April 2023.
All employers should have specific and up-to-date policies dealing with how workplace investigations will be carried out that are suitable for their organisation. These policies may vary, depending on the subject of the investigation and the size and type of employer. However, all should adhere to the principles identified above to ensure that a robust policy is in place and can be utilised.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

In the UK, the primary employment legislation of relevance to a workplace investigation includes the Employment Rights Act 1996 (ERA 1996), the Equality Act 2010 (EA 2010), and the Employment Relations Act 1999 (ERA 1999).
Other legislation includes the retained EU law version of the General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA 2018), the Investigatory Powers Act 2016 (IPA 2016) and the Investigatory Powers (Interception by Businesses etc for Monitoring and Record-keeping Purposes) Regulations 2018 (IP Regs 2018), and the Humans Rights Act 1998 (HRA 1998).
In terms of guidance, the Advisory, Conciliation and Arbitration Service (ACAS) have produced a Code of Practice on Disciplinary and Grievance Procedures (the ACAS Code) as well as a Guide to conducting workplace investigations. The Information Commissioner’s Office (ICO) have their Employment Practices Code, and other pieces of guidance on the data protection aspects of investigations (see question 7).
Most employers will have internal policies governing how workplace investigations should be conducted. The level of detail may vary considerably; public sector and regulated employers may be more prescriptive in their policies, which may even have contractual force. There may also be provisions of the employment contract that are relevant (particularly as regards suspension – see question 3).

A failure to follow fair procedures in the investigation can have significant consequences.
Although the exception rather than the rule, an employee could challenge the investigation through injunctive proceedings if there is a breach of fair procedures. Such action would be taken before the High Court. Injunction proceedings may be brought while the investigation is ongoing, or just before its conclusion to prevent publication of a report making specific findings against an employee. A successful injunction may curtail any subsequent attempt to investigate the matter as allegations of penalisation, prejudice and delay may arise.
Errors during the investigation can also give rise to a complaint of constructive dismissal, with allegations that flaws in the procedure have fundamentally breached the implied term of mutual trust and confidence.
A flawed investigation can also undermine any disciplinary process and sanction that is imposed as a result. This commonly occurs when an employee has been dismissed following a disciplinary process launched on foot of the investigation. While dismissal may be an appropriate sanction, the dismissal can still be found to be unfair if there is a failure to follow fair procedures. An employee may challenge their dismissal before the WRC and the employer should be alive to not only an unfair dismissal complaint, but allegations of discrimination and penalisation.
Overall, to carry out a successful workplace investigation, an employer should consider taking advice at the earliest opportunity to ensure that the investigation can withstand challenges.

As there are no specific regulations for internal investigations, the usual legal framework within which the employer must act towards the employee derives from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights.
But, for example, unwarranted surveillance could conceivably result in criminal liability (article 179 et seq, Swiss Criminal Code) for violations of the employee's privacy. Furthermore, errors made by the employer could have an impact on any later criminal proceedings (eg, in the form of prohibitions on the use of evidence).[1]
Evidence obtained unlawfully may only be used in civil proceedings if there is an overriding interest in establishing the truth (article 152 paragraph 2, Swiss Civil Procedure Code). Consequently, in each case, a balance must be struck between the individual’s interest in not using the evidence and in establishing the truth.[2] The question of the admissibility of evidence based on an unlawful invasion of privacy is a sensitive one – admissibility in this case is likely to be accepted only with restraint.[3] Since the parties in civil proceedings do not have any means of coercion at their disposal, it is not necessary, in contrast to criminal proceedings, to examine whether the evidence could also have been obtained by legal means.[4]
Unlawful action by the employer may also have consequences on future criminal proceedings: The prohibitions on exploitation (article 140 et seq, Swiss Criminal Procedure Code) apply a priori only to evidence obtained directly from public authorities. Evidence obtained unlawfully by private persons (ie, the employer) may also be used if it could have been lawfully obtained by the authority and if the interest in establishing the truth outweighs the interest of the individual in not using the evidence.[5] Art. 140 paragraph 1 Swiss Criminal Procure Code remains reserved: Evidence obtained in violation of Art. 140 paragraph 1 Swiss Criminal Procure Code is subject to an absolute ban on the use of evidence (e.g. evidence obtained under the use of torture[6]).[7]

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.
