Workplace Investigations

In general terms, NDAs can be used and indeed are commonly used to keep the fact and substance of a workplace investigation confidential. However, NDAs will not be effective in preventing the disclosure of information which is in the public interest or is important for safeguarding public welfare in matters of health and safety. Further, several laws in Hong Kong provide that disclosures as a result of compliance with a requirement made by the relevant authorities will not be treated as a breach of any restriction imposed by contract or otherwise by law.[1]

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

It is crucial to keep the events and facts of a workplace investigation confidential for the integrity of the process. It may be necessary to consider appropriate confidentiality measures to protect the complainant, mitigate risks, and preserve evidence. Damage to the confidentiality of the case can prevent the investigation team from bringing the case to a correct and complete conclusion. Although the labour legislation imposes a general confidentiality obligation on employees, NDAs can still be used as supplementary documents that may emphasise the confidentiality obligations of employees in workplace investigations and provide additional contractual protections such as penalties if there is a breach.

The employer is generally not obliged to share the investigation report or the findings with the employee under Hong Kong law, absent any express obligations under the employment contract.

However, according to the PDPO, the content of the investigation report or meeting minutes related to the employee (including any findings and opinions expressed in such documents) are likely to constitute the personal data of the employee under investigation. In that case, the employee may have a right under the PDPO to obtain a copy of such documents by making a statutory data access request after the workplace investigation is completed. The employer’s obligation to comply with such request is subject to certain exemptions under Part 8 of the PDPO, which include (among others) an exemption on the provision of personal data held for the prevention, preclusion or remedying of unlawful or seriously improper conduct, and the disclosure of which would be likely to prejudice the said purpose or directly or indirectly identify the person who is the source of the data.[1] Therefore, where there is a parallel criminal proceeding or investigation that has not been concluded, the employer may reject an employee’s data access request on the basis that the requested disclosure may prejudice the prevention and remedy of the unlawful conduct. Further, any information protected by legal privilege is also exempt from disclosure under Part 8 of the PDPO.[2]

If the requested documents also contain the personal data of any other third parties (such as other co-workers of the employee who have also participated in the investigation), the employer should always redact or erase such data before providing the requested documents to the employee under investigation, unless the relevant third parties have consented to the disclosure of the data.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

There is no legal requirement for the disclosure of the investigation report in full. If the investigation report needs to be submitted to the court, public institutions or other third parties, measures may need to be taken to protect confidentiality or to comply with the confidentiality requests of the persons participating in the investigation.
