Workplace Investigations

Once the decision to undertake a workplace investigation has been made, it is important to decide who is the most appropriate person to conduct the investigation. For the investigation process to run smoothly a single lead investigator should be selected, although they may work with a larger team. The lead investigator and investigation team can be internally or externally appointed.

In deciding whether to appoint an external investigator an employer should consider:

• the nature of the allegations;
• the seniority of the respondent;
• whether a fair investigation can be conducted internally without any actual or perceived bias;
• whether there is a dedicated HR department with someone who has the required capability, skills and experience to conduct the investigation; and
• whether the employer wants the investigation to be covered by legal professional privilege.

If the employer decides to investigate the matter internally without appointing a third party, then the investigator does not need to have any specific qualifications. However, it is prudent to confirm that the investigator has the time and skills to conduct the investigation and that they can be objective.   

There are no legal requirements in this regard but it is good practice if the team of investigators or individuals who deal with the case consists of:

• a person who has specific knowledge in a given field (concerning the violation);
• a member of the HR team; and
• a lawyer (it is recommended to engage an independent, external lawyer who can maintain the objectivity of the investigation, especially in complex matters or where a conflict of interest arises or may arise).

It is crucial that the investigators are independent (and they must be allowed to act independently).

Also, certain personal features are useful (eg, the ability to objectively assess a situation, empathy, and managing skills).

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

A trade union does not have any right to be informed of, or involved in, an investigation by an employer. However, an employee may request that their support person is a trade union member or trade union representative. This is appropriate and should be permitted.

Employers should review the terms of an employment contract, policy or industrial instrument as this may contain terms regarding trade union involvement. In particular, heavily-unionised workplaces may contain enterprise agreements which contain relevant clauses.

There is no such obligation, unless it is provided for in an internal procedure or, for example, in the applicable collective bargaining agreement. It is neither a recognised practice nor recommended that such persons participate in the investigation.

However, in the event of violations that justify the termination of an employment contract with the employee, the employer should consult with that employee’s union about their intention to immediately terminate any employment contract concluded with that person or to terminate, with notice, the employment contract agreed with him or her for an indefinite term, or apply for consent to terminate the employment contract with an employee who is protected by a union.

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.
