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.

If the employer decides on an internal investigation to assess potential wrongful actions carried out within the company, employees must cooperate. However, employees are entitled to the privilege against self-incrimination established in the Portuguese Criminal Code, according to which individuals are not obliged to self-report.

An employee's refusal to cooperate with an internal investigation may be regarded as a breach of conduct by the employer and, ultimately, may lead to disciplinary sanctions.

Employees who act as witnesses in cases of harassment cannot be sanctioned unless they acted with wilful misconduct, and any sanction applied to an employee who acted as a witness in a harassment procedure will be presumed to be abusive.

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]

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.

Employee representative bodies are not entitled to be informed about or to participate in the preliminary investigation. The works council is only entitled to participate in disciplinary proceedings after a formal accusation has been made against the employee.

A copy of the accusation should be sent to the works council (if any) and if the employee is a trade union member, to the respective trade union. After the instruction phase of the procedure has ended (where the employer has to hear the witnesses identified by the employee in his written defence and file any other sources of information that have been requested), the employer should provide a copy of the disciplinary procedure to the works council (if any) and the respective trade union, if the employee is a member. These employees’ representatives will then have five business days to issue their opinion on the matter.

Finally, a copy of the final decision must also be sent to these bodies.

There is no legal right for the interviewee to be assisted by a representative from the works council.

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.

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.

Once the preliminary investigation ends, the employer must decide whether or not, in its view, there are grounds to bring an accusation against the employee and enforce disciplinary action or if it should be dismissed due to a lack of evidence.

When the employer decides to enforce disciplinary action, the following sanctions may be applied:

• verbal warning;
• written warning;
• financial penalty;
• loss of holiday;
• suspension with loss of pay and length of service;
• dismissal with cause and without compensation.

The first five penalties are usually called conservatory sanctions, enabling the continuity of the employment relationship, as opposed to dismissal, which is deemed a measure of last resort.

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.
