Workplace Investigations

Files and documents that are purely business-related – whether in physical or digital form – may, in principle, be inspected by the employer without restriction. The employee has no right to refuse inspection.

When searching business laptops, computers, phones and e-mail accounts, a distinction must be made as to whether private use is permitted (or at least tolerated) or not: if the employee is allowed to use the items exclusively for business purposes, the employer may monitor and control them. If private use is permitted, the employee's right to privacy must be observed for private files, as must the protection of the secrecy of correspondence. Accordingly, the employer must avoid accessing private documents, files and e-mails. However, a review of private documents, files and e-mails may be permissible in the event of particularly serious violations if the employer's interest in the review outweighs the employee's interest in safeguarding his right to privacy. Generally, employers should allow private use of electronic devices only if employees have previously consented to the terms of use (including searches in certain cases).

A search of the employee's workplace by the employer is, in principle, permissible. However, a search of personal items (eg, bags, clothes, personal mobile phone) is generally only permissible with the employee's consent. Similarly to the review of digital personal data, a search of personal items may be permitted, however, in the event of particularly serious violations if the employer's interest in the search outweighs the employee's right to privacy.

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]

Depending on the subject of the investigation and the severity and significance of the suspected violation, employees who are involved in the workplace investigation may already have to maintain confidentiality based on their contractual duties. The prerequisite for this is that the employer has a legitimate interest in maintaining confidentiality. Criminal acts are not subject to confidentiality, but there is also no general obligation for the employee to report or disclose a criminal act to the authorities or the public prosecutor. However, reporting to the competent authorities may be required in certain cases (see question 25).

Lawyers are bound by professional confidentiality and are generally not allowed to provide information about any information they receive from their clients. An exception exists, for example, if the lawyer must provide information to defend himself in court proceedings. There is also no absolute protection against the seizure of documents at an attorney’s office (see question 14).

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]
