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]

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]

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]
