Workplace Investigations

Although there are no specific laws or regulations regulating the extent of confidentiality obligation employers or the investigators shall comply with, in practice, the confidentiality obligation of both parties usually originates from the confidentiality agreement between the employee and the employer, as well as general provisions on protection of personal information and right of privacy, etc.

In this regard, it is advisable to require the relevant personnel responsible for handling the suspension for investigation to sign a confidentiality agreement or a letter of commitment, and require them to pay attention to the protection of the personal information and privacy of the complainant and other relevant personnel, for the purpose of avoiding extra losses caused by the occurrence of disputes relating to right of reputation, right of privacy and personal information leakage during the investigation.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

Workplace investigations should usually be conducted on a confidential basis, so that only those involved in the investigation are aware of its existence and subject matter. The need to maintain confidentiality about both the fact of the investigation, and any content discussed with an investigator, should be emphasised to all those involved. It may also be necessary to explain that a breach of confidentiality could be viewed as a disciplinary matter. Appropriate exceptions must, however, be made to allow employees to speak to any relevant employee or trade union representative, legal adviser and potentially the police or other regulators. Confidentiality provisions cannot override the rights of workers to make protected disclosures (see question 9).

In some situations, such as those involving a wide-ranging investigation into the organisation’s working practices and culture, it may be more appropriate to investigate a more “open” basis, and inform employees and other stakeholders.

The employer has the property right over all its properties. When discovering employee's misconduct, the employer is entitled to conduct an investigation within a certain scope according to the relevant laws and regulations, as well as the management system of the employer. Generally speaking, the employer is not required to obtain consent of the employee when conducting an investigation of the space and objects owned by it. The employer has no right to directly conduct an investigation of the employee's private space, objects, bank accounts and stock trading accounts. The public security organ or other public authorities should be involved in the investigation. In principle, if the employee's private space or objects are mixed with the employer's private space or objects, the employer should obtain consent of the employee for an investigation. Meanwhile, the employer's investigation should be controlled within the reasonable and necessary limit, and the employer is not allowed to illegally use or disclose the investigation results, otherwise it may constitute infringement. In addition, we also recommend that the employer stipulate explicitly in the employment contract and the internal management system that the employer has the right to detain and inspect the articles or equipment distributed by the employer, so as to reduce the compliance risk of internal investigation.

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.

There are two limited types of privilege which may be relevant to investigations:

• Legal Advice Privilege (LAP), which protects communications between lawyers and their clients provided they are confidential and made for the dominant purpose of obtaining or giving legal advice; and
• Litigation Privilege (LP), which can extend to communications between a lawyer and client or third parties, but only where the dominant purpose of the communication is to prepare for or conduct existing or contemplated litigation.

If the relevant tests for privilege are met and apply to materials generated in the course of the investigation, the employer retains greater control over their subsequent disclosure to third parties. The materials would, for example, be protected against disclosure in any subject access request under the DPA 2018.

That said, privilege can be difficult to maintain in investigations, particularly where litigation is not active or in contemplation. Interview notes and witness statements may not attract privilege, particularly if these were conducted with employees who do not fall within the narrow definition of “the client” for LAP purposes (which is limited to employees who are capable of seeking and receiving advice on behalf of the employer).

If privilege applies to investigation materials, the investigator should keep tight control on what documents are created and how they are circulated, to avoid inadvertent disclosure and potential waiver of privilege.

Bear in mind that even if privilege applies to certain investigation materials, there may be a need to create disclosable documentation at a later stage, particularly if there is a decision to instigate disciplinary action.
