Workplace Investigations

Privilege attaches to investigation materials when attorneys conduct interviews and take notes, and when they write reports and recommendations.

However, if other persons participate in an interview or write a report, and they are not attorneys, they can be required to testify about what they witnessed while participating in the interview or to discuss or disclose their investigation report.

For this reason, when starting an investigation, and depending on the matters to be investigated, it is important to determine whether it is convenient to allocate lawyers to certain roles to increase the company’s control of corporate confidentiality resulting from third-party involvement in the investigation.

Attorneys should also clearly state to participants of the investigation that they are attorneys representing the company and that their work papers fall under attorney-client privilege and will not be shared with them.

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.

It is highly recommended that investigation interviews are conducted in the interviewed person’s native language, even if the individual speaks the language used for business within the company, to ensure that there is no miscommunication or loss of accuracy in the determination of the facts. Also, speaking their native tongue reduces the discomfort of participating in the interview and potential extra work due to post-interview correction or confirmation. Depending on the scope of the investigation, the company can have attorneys who speak both the individual’s language and the company’s business language conducting interviews.

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[2]
