Workplace Investigations

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]

The company may be required to share information or documents with authorities such as a judge, the police, or the Public Attorney's office, or be subject to a government authority’s dawn raid. Workplace investigations can and in most cases should continue, and in such circumstances client-work privilege will be essential to enable the employer to control information being shared with third parties.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
