Workplace Investigations

Having been informed of an alleged infraction committed by an employee, the employer must prepare a detailed written accusation and notify the employee.

Moreover, if the alleged infraction constitutes gross misconduct and the employer is considering dismissal, a formal statement of the employer’s intention to dismiss the employee should accompany the accusation. If this is not expressly done, the employer will be unable to dismiss the employee and may only apply one of the conservatory sanctions. A copy of these documents must be sent to the works council, if any, and, should the employee be a union member, to the respective trade union.

Notwithstanding this, if before preparing the accusation the employer needs to further investigate the facts and circumstances, it may open a preliminary investigation aimed at collecting all the facts and circumstances and conclude if there are grounds to bring an accusation against the employee.

The preliminary investigation must start within 30 days of the employer becoming aware of the facts, be diligently carried out (but with no maximum period laid down by law) and concluded within 30 days of the last investigatory act. Furthermore, the preliminary investigation will suspend the relevant statutory deadlines and statutes of limitations (ie, 60 days from the date of acknowledgment, by the employer or a supervisor with disciplinary power, of the facts to enforce disciplinary action against the employee and one year from when the facts occurred, regardless of the employer’s acknowledgment, unless the infraction also constitutes a criminal offence, in which case the longer statutes of limitation established in criminal law will apply).

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

A workplace investigation is often, although not always, prompted by a complaint of workplace misconduct, usually made directly by the employee who was harmed by the conduct, a third party who witnessed the conduct, or a manager or supervisor who was made aware of the issue and has reporting obligations as a result of his or her role in the organisation. 

It is best practice – and often a legal requirement depending on the applicable state law – for companies to clearly outline a complaint process in their policies and to provide employees who experience, have knowledge of, or witness incidents they believe to violate the company’s policies with one or more options for making a report. Although the specific complaint procedure may vary depending on the size of the organisation, the nature of the business and the type of complaint at issue, many companies provide for (or require) making a report through one of the following channels:

• a company-managed hotline or online equivalent;
•  human resources;
• an affected employee’s supervisor or manager; or
• a member of the legal or compliance department.    

These procedures are independent and autonomous, and the law does not provide any particular rules to ensure coordination. This raises particular concerns when an employee is subject to a criminal investigation in secret, as the employer will be unable to access any evidence from the criminal procedure to begin an internal investigation or disciplinary procedure against the employee.

On the other hand, considering the short statutes of limitation to enforce disciplinary action, it may prove impossible to wait for the outcome of the criminal or regulatory investigation to decide if a disciplinary procedure should also be enforced, because by the time the employer is fully aware of the facts, the statutes of limitation may have already expired.

However, both the judge in a criminal procedure and the regulator have the public authority to order the employer to share any findings within the scope of the investigation or disciplinary procedure.

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).

Employers have obligations to conduct a thorough and unbiased internal investigation and take prompt remedial action to prevent further workplace violations. As such, absent a criminal or regulatory investigation where the investigators ask the employer to pause an internal investigation, employers should be prepared to continue their internal investigation in parallel with the criminal or regulatory investigation while cooperating with police or regulatory investigators.

The police and the regulator can often compel the employer to share certain information gathered from its internal investigation. In some cases, the employer should analyse whether the non-disclosure of information evidencing criminal conduct within the company itself constitutes an independent crime or whether an applicable statute or regulation imposes an independent duty to disclose. Alternatively, the employer should consider whether, even absent an affirmative duty to disclose, disclosure of information gathered during an internal investigation may still benefit the employer.
