Workplace Investigations

As part of an investigation, an employer may search objects or files that are the company’s property (eg, electronic devices given by the employer for business purposes and emails or messages stored on the company’s server) without prior notice and the employee’s consent is not needed. The employer, however, has no right to search an employee’s possessions (eg, a private smartphone) without the employee’s consent.

To avoid arguments as to who a particular object belongs to, employers may specify in internal policies what is to be regarded as a corporate asset and could be subject to a search in a workplace investigation.

Concerning an employee’s possessions, even if he or she consents to a search, it is good practice for the employer to conduct the search in the presence of the employee or an independent third party who can act as a witness to the search. If the employer suspects that a criminal offence has been committed and that a search of the employee’s possessions would reveal evidence, the employer should consider reporting its suspicion to the police, as they have wider legal powers to search.[1]

When conducting an internal investigation (which must have a legitimate purpose), the employer must act in accordance with the principles of proportionality and subsidiarity. In line with these principles, the means of collecting and processing personal data during an internal investigation as well as the data that is searched, collected or processed, should be adequate, relevant and not excessive given the purposes for which the data is being collected or subsequently processed. These principles can be complied with by, for example, using specific search terms when searching electronic data, limiting the investigation’s scope (subject matter, period, geographic locations) and, in principle, excluding an employee's private data.

The employer is, in principle, allowed to access documents, emails and internet connection history saved on computers that were provided to the employees to perform their duties, provided the requirements of proportionality and subsidiarity are taken into account. In other words, reading the employee's emails or searching electronic devices provided by the employer must serve a legitimate purpose (e.g. tracing suspected irregularities or abuse) and the manner of review or collecting and processing the data contained in such emails should be in accordance with the principles of proportionality and subsidiarity.

The employer can ask the employee to hand over an employee's USB stick for an investigation. Depending on company policies and (individual or collective) employment agreements, an employee is, in principle, not obliged to comply with such a request. A refusal from an employee, when there is a strong indication that this USB stick contains information that is relevant to an investigation into possible irregularities, may be to the disadvantage of an employee, for example in a dismissal case.

The following factors, which derive from the Bărbulescu judgment of the European Court of Human Rights, are relevant to the question of whether an employee's e-mail or internet use can be monitored:

• whether the employee has been informed in advance of (the nature of) the possible monitoring of correspondence and other communications by the employer;
• the extent of the monitoring and the seriousness of the intrusion into the employee's privacy;
• whether the employer has put forward legitimate grounds for justifying the monitoring;
• whether a monitoring system using less intrusive methods and measures would have been possible;
• the consequences of the monitoring for the employee; and
• whether the employee has been afforded adequate safeguards, in particular in the case of intrusive forms of monitoring.

These requirements can sometimes create a barrier for employers, as seen in a ruling by the District Court Midden-Nederland (16 December 2021, ECLI:NL:RBMNE:2021:6071) in which the employer had used information obtained from the employee's e-mail as the basis for a request for termination of the employment contract. In the proceedings, the employee argued that his employer did not have the authority to search his e-mail.

According to the District Court, it was unclear whether the employer had complied with the requirements of Bărbulescu regarding searching the employee's e-mail. The regulations submitted by the employer only described the processing of data flows within the organisation in general. Therefore, the District Court found that the employer did not have a (sufficient) e-mail and internet protocol and the employee was not properly informed that his employer could monitor him. In addition, according to the District Court, it was unclear what exactly prompted the employer to search the employee's e-mail, as the employer did not provide any insight into the nature and content of the investigation. As a result, the District Court was unable to determine whether the employer had legitimate grounds to search the employee's e-mail. On this basis, the District Court disregarded the (possibly) illegally obtained evidence and ruled against the employer's termination request.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

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.

In case there is a parallel criminal or regulatory investigation usually consultation between the investigators and the authorities takes place. Agreements are then sometimes made about the investigation conducted by / for the employer. In some cases, the authorities will ask to stay the investigation. There is no policy from the government on this topic.

There are situations where the authorities can compel the employer to share evidence. This depends on the exact circumstances of the case. For instance if the employer is the suspect in a criminal case.

It does occur that the authorities are given evidence upon request without the authorities having to order the extradition of evidence.  

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).
