Workplace Investigations

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.

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).

There is no legal requirement in Hong Kong on this. However, since the investigation records will likely contain personal data, employers should be mindful of the requirement under the PDPO that personal data should not be kept for longer than necessary.[1]

According to the Code of Practice on Human Resources Management published by the Privacy Commissioner for Personal Data, generally, employment data about an employee can be kept for the entire duration of his or her employment, plus a recommended period of no more than seven years after the employee leaves employment unless there is a subsisting reason that justifies a longer retention period. A longer retention period may be justified where there is ongoing litigation or a parallel investigation. Even where it is deemed necessary to retain the outcome of the investigation concerning a departed employee, the employer should ensure that other personal data on the employee’s record (that is unrelated to the purpose of retention) are erased after the expiry of the recommended retention period.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]
