Workplace Investigations

Workplace investigations should usually be conducted on a confidential basis to preserve the integrity of the investigation, avoid cross-contamination of evidence and maintain the confidentiality of the employee under investigation. This means that those involved in the investigation (ie, the subject employee and any material witnesses) should be made aware of the fact and substance of the investigation on a need-to-know basis.

While the extent of the confidentiality obligations are usually governed by the employer’s internal policies and the employment contract, there are circumstances where the employer has a statutory duty to keep information unearthed in the investigation confidential. For instance, if it is found that certain property represents proceeds of an indictable offence[1] or drug trafficking[2], or is terrorist property[3], the employer should report its knowledge or suspicion to the Joint Financial Intelligence Unit (JFIU) as soon as is reasonably practicable and avoid disclosure to any other person as such disclosure may constitute “tipping off”. Another example is if a workplace investigation is commenced in response to a regulatory enquiry, the employer may be bound by a statutory secrecy obligation and may not be at liberty to disclose anything about the regulatory enquiry to anyone including those who are subject to the workplace investigation. For example, section 378 of the Securities and Futures Ordinance (SFO) imposes such a secrecy obligation on anyone who is under investigation or assists the Securities and Futures Commission (SFC) in an investigation.[4]

This will depend on the nature of the investigation but, generally, investigations should be conducted on a confidential basis. All who participate in the investigation should be informed and reminded that confidentiality is a paramount consideration taken very seriously. However, it should be borne in mind that confidentiality cannot be guaranteed by an employer as the respondent in an investigation is entitled to know who has made complaints against them. Furthermore, the respondent is entitled to cross-examine the complainant and any witnesses, although in practice this right is rarely invoked strictly and is facilitated by the investigator, with questions from the respondent being put to the complainant and other witnesses.

On occasion, a breach of confidentiality may warrant disciplinary action, but this will depend on the circumstances. Exceptions to the requirement to keep matters confidential will of course apply where employees seek support and advice from others such as companions, trade union representatives or legal advisors. It may also not be possible to maintain confidentiality where regulators or the authorities are informed of the investigation.

Also, confidentiality may not be maintained if it is in the interests of the employer to communicate the complaint and any subsequent investigation, for example on a health and safety basis.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

Where there is a parallel criminal or regulatory investigation, the employer should handle the workplace investigation with extra care and ensure that it complies with all applicable legal requirements or lawful requests made by the relevant authorities concurrently. While there may be reasons why the employer wants to progress with its investigation as soon as possible, the employer should not take any steps that hinder or obstruct the parallel investigations. Therefore, it may be appropriate for the employer to stay its workplace investigation if its continuation may prejudice the parallel investigations.

The employer may also find itself duty-bound to stay the workplace investigation if it is subject to statutory secrecy obligations vis-à-vis the relevant law enforcement agency or regulatory body. As mentioned in question 10, several laws in Hong Kong impose secrecy obligations on any person who has acquired confidential information about certain law enforcement agencies or regulatory bodies and the investigations being conducted. The employer should assess whether they could continue with the workplace investigation without breaching secrecy obligations. The employer should take a prudent approach and may discuss with the relevant authority before proceeding further with its workplace investigation.

Depending on the nature of the matter, authorities in Hong Kong handling a criminal or regulatory investigation may be empowered to seize, or compel persons who are the subject of an investigation or assisting in such an investigation (which may include the employer) to produce, documents or evidence that are relevant to the matters being investigated. For example:

• the police or the Independent Commission Against Corruption may, under a search warrant (or in certain circumstances, without a warrant), inspect and take possession of articles or documents inside the premise of the employer they reasonably suspect to be of value to the investigation of the suspected offence; and
• the SFC or the Competition Commission may, under the SFO or Competition Ordinance (as applicable), require the employee under investigation or the employer to produce documents, attend interviews, and, specifically for the SFC, provide the investigator with all assistance he or she ­­­can give. Both authorities may also obtain a warrant from the Hong Kong courts to search the premise of the employer and obtain documents or information it reasonably believes to be relevant to its investigation.

Documents created and evidence gathered by the employer during its workplace investigation (such as witness statements or investigation reports) may be subject to production requests of, or may be seized by, the authorities mentioned above (unless legal professional privilege is attached). The employer should ensure that it complies with all lawful requests from the authorities.

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).
