Workplace Investigations

The identity of the complainant must be kept confidential and cannot be disclosed. There are two exceptions: if the complainant consents to the disclosure; or if the employer is asked for this information by the judicial authorities.

Failure by an employer to provide the identity of the complainant, witnesses or sources of information seriously impinges upon the employee's right to fair procedure and could result in a flawed investigation.

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]

A criminal investigation always takes precedence over other investigations. However, this does not mean that the internal investigation has to stop. It can and should continue, and the report drawn up upon completion of the investigation could be used by the authorities in the criminal investigation. In some cases, especially when privilege does not apply, police or regulatory authorities may request that the employer share such evidence. However, even when privilege does apply, there is no certainty that the evidence would not have to be communicated to certain authorities.

Some administrative authorities often challenge the application of legal privilege or try to reduce its scope. For example, the French financial markets authority (AMF) regularly puts forward its view of legal privilege, according to which an email where a lawyer is only copied (and is not one of the main recipients) in from one of their clients is not confidential and can therefore be disclosed in proceedings. However, if the AMF investigators impose disclosure of privileged documents, this should result in the annulment of the investigation procedure. By way of exception, legal privilege cannot be invoked against certain other authorities, such as the URSSAF (authority in charge of collecting social security contributions) or the DGCCRF (directorate-general for competition, consumer protection and anti-fraud investigations). Where legal privilege is enforceable, the judge must first determine whether the documents constitute correspondence relating to defence rights and, second, must cancel the seizure of documents that they find to be covered by legal privilege due to the principle of professional secrecy of relations between a lawyer and their client and the rights of defence.

Workplace investigations can originate from criminal investigations or proceedings. It may be that an employer only becomes aware of a matter through the involvement of the police (An Garda Siochana) or regulatory bodies.

If a criminal investigation is pending it can complicate a workplace investigation, but it will be specific to the nature of the complaint. Likewise, where a regulatory investigation is in scope, an employee may argue that any internal investigation should be put on hold, on the basis that it will harm any regulatory investigation. Such matters will be dealt with on a case-by-case basis as it may be some time before any regulation investigation commences, by which time the workplace investigation and any subsequent process may have been concluded.

Employers will also have to consider their reporting obligations to An Garda Siochana. If the matter relates to fraud, misuse of public money, bribery, corruption or money laundering, for example, reporting obligations arise under section 19 of the Criminal Justice Act 2011. A failure to report information that an employer knows or believes might be of material assistance in preventing the commission of an offence, or assisting in the apprehension, prosecution or conviction of another person may be guilty of an offence.

Also, the Irish Central Bank's (Individual Accountability Framework) Act 2023 (the Act) was signed into law on 9 March 2023 but has not yet been enacted. The framework provides scope for a senior executive accountability regime, which will initially only apply to banks, insurers and certain MiFID firms. However, its application may be extended soon. The Act forces employers to engage in disciplinary action against those who may have breached specific "Conduct Standards".

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
