Workplace Investigations

Co-workers can be interviewed as part of an investigation where they are witnesses to a complaint.  If the employee refuses to attend the interview or is generally not cooperating with the investigation, the reasons for this will need to be considered carefully by the employer. Employers should consider whether there can be any amendments made to the interview process to accommodate the employee. However, an employer can make a reasonable and lawful direction to an employee to attend an interview. If an employee fails to comply with a lawful and reasonable direction, then it may constitute grounds for disciplinary action.  

Witnesses who are employees are entitled to the legal protections that ordinarily attach to their employment, including not being bullied, discriminated against, or harassed and having their health and safety protected. Employers should also ensure that witnesses are not victimised as a result of participating in the investigation and that confidentiality is maintained.

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.

The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

Investigation materials are not privileged and an employer may be required to disclose them in subsequent legal proceedings. If an employer is concerned about privilege attaching to an investigation, they should engage a legal practitioner to facilitate the investigation.

Employers who are concerned about privilege attaching to investigation materials should also consider the method of a lawyer’s engagement. The lawyer should be expressly engaged to investigate, report and to assist the employer by providing legal advice. Additional benefits can be achieved if the legal practitioner engages an external investigator to investigate the complaint and prepare the investigation report. Privilege will attach to the investigation materials because they are prepared for the lawyer to allow the lawyer to provide legal advice to the employer.

It is important that employers do not expressly or inadvertently waive privilege. For example, by disclosing the investigation report or substantial contents of the investigation report. It is a balance between providing information to the respondent and complainant about the outcome of the investigation and disclosing too much information.

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.

During the investigation, unrelated matters can come to light, usually made by the complainant or a witness during the interview process. Unrelated matters may take the form of further complaints against the respondent (but on grounds that are outside the scope of the current investigation), or entirely different complaints.

An employer should first assess the nature of the new allegations. Entirely unrelated matters should be dealt with separately. However, if the matter relates to the respondent it may be appropriate to obtain consent from the respondent and complainant for the scope of the investigation to be widened. It is important to remember that all allegations must be put to the respondent and they must be given an opportunity to respond.

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.

Employers must take steps to deal with the findings of the investigation and implement any recommendations promptly. This may involve commencing disciplinary action.

The complainant and respondent need to be informed of the outcome of the investigation. All witnesses who participated in the investigation should also be thanked for their contribution and advised that the investigation has been completed. All participants in an investigation should be reminded of their ongoing obligations concerning confidentiality and victimisation.

If an employer decides that it may be appropriate to terminate a respondent’s employment, the employee must be provided with the opportunity to respond and to “show cause” as to why their employment should not be terminated.

The investigation report along with any other materials produced during the investigation should be kept in a separate confidential file.

Employers should also consider whether action should be taken at an organisational level to prevent future misconduct. In particular, employers are required to take a proactive approach to addressing systemic workplace cultural issues in relation to sex discrimination, sexual harassment and victimisation.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.
