Workplace Investigations

Privilege does not generally apply to internal investigation materials as the investigation does not constitute a relationship between a lawyer and their client, and even less so a judicial investigation. However, if a lawyer is appointed as an investigator, privilege may apply to materials exchanged between the lawyer and that client.

Legal professional privilege may attach to investigation materials if they are generated for the sole or dominant purpose of giving or obtaining legal advice (legal advice privilege); or created with the sole or dominant purpose of either obtaining or giving advice about or obtaining evidence to be used in an actual or reasonably contemplated litigation (litigation privilege).[1] Legal advice privilege applies to confidential communications between lawyers and their clients, whereas litigation privilege may extend to communications between lawyers, clients and third parties. The employer may withhold disclosure of any materials that are subject to either legal advice or litigation privilege.

In the context of a workplace investigation, internal interview records are protected by legal advice privilege if the dominant purpose of creating those records is to seek legal advice on potential disciplinary action against the employee. Such interview records are protected by litigation privilege if they are created to obtain evidence in an actual or reasonably contemplated litigation.

It should be noted that the point in time at which the sole or dominant purpose is judged is when the document is created. In other words, a document is not covered by litigation privilege if it was not created for litigation purposes but was subsequently used to obtain legal advice for litigation.[2] On a practical point, if the employer would like to minimise disclosure of the investigation by claiming privilege over relevant materials, it may wish to limit the number of documents created and persons to which they are circulated to avoid potential waiver of privilege.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

If the outcome of the internal investigation has led to the sanctioning of an employee, this sanction may no longer be invoked to support a new sanction after three years. Moreover, under the GDPR principles, the duration of retention must be proportional to the use of the data. Therefore, the data must be retained only for a period that is “strictly necessary and proportionate”. If the employer wants to keep information about the investigation in the longer term, it is possible to archive the employee’s record even though the employer will no longer be able to use it against the employee after three years.

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]
