Workplace Investigations

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 employer’s counsel should provide an Upjohn warning at the start of any interview, and delivery of the warning should be documented by a note-taker. An Upjohn warning is the notice an attorney (in-house or outside counsel) provides a company employee to inform the employee that the attorney represents only the company and not the employee individually.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.

Where new issues or claims arise during an ongoing workplace investigation, the investigator should discuss with in-house counsel whether the new issues or claims should be separately investigated and if so, by whom, or if instead those new issues or claims are sufficiently related to the current review that they can be investigated in parallel and incorporated into the ongoing fact-gathering process.
