Workplace Investigations

A workplace investigation will generally be triggered by an employee making a complaint; however, issues may also be brought to the attention of an employer through an anonymous tip, by suppliers or contractors, from customers or because of observations and hearsay.

Complaints can be made directly to Human Resources (HR), anonymously, by email to a line manager or a third party. While complaints do not need to be written and can be informal, brief or verbal, complaints of this nature can make the process harder and more information may be required.

The receipt of a complaint does not necessarily mean that an employer needs to undertake an investigation immediately. A grievance policy ordinarily contains a multi-step approach to dealing with complaints, starting with internal resolution options such as informal discussions, conciliation and mediation. However, an investigation should be commenced where:

• the complaint alleges serious misconduct or unlawful conduct;
• the employer is required to conduct a workplace investigation as per an employment contract, policy, procedure or industrial instrument; or
• the complaint is complex and requires clarity on what has occurred to establish the facts.

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]

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]

The starting position is that there is no general right for an employer to search an employee’s possessions. However, an employer may be able to undertake a search in circumstances where:

• the employee consents to the search;
• there is a “right to search” contained in a contract, policy, procedure or industrial instrument; or
• the request to search constitutes a lawful and reasonable direction.

If an employee agrees to a search of their possessions, this consent should be confirmed in writing. If the employee does not consent then the employer can issue a direction to the employee. If the direction is lawful and reasonable, and the employee does not comply, then disciplinary action may be considered.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]
