Workplace Investigations

In internal investigations, the fundamental rights and freedoms of employees are at stake,  including the right to privacy, respect for the privacy of home life and correspondence, freedom of expression, and the obligation of loyalty in searching for evidence.

In principle, work emails and files can be reviewed, even without the employee's consent, prior knowledge or warning. This includes: work email accounts; files stored on a work computer or a USB key connected to a work computer; and SMS messages and files stored on a work mobile phone and documents stored in the workplace unless they are labelled as “personal”. On the other hand, it is not permissible for an employer (or an investigator) to review “personal” emails and files, such as documents or emails identified as “personal” by the employee, or personal email accounts (Gmail, Yahoo, etc), even if accessed from a work computer.

There are certain exceptions to the above principle. An employer is allowed to check “personal” emails or data in any of the following cases:

• if the employee is present during the review;
• if the employee is absent, but was duly notified and invited to be present;
• if there is a particularly serious “specific risk or event”;
• if the review is authorised by a judge (this means having to prove a legitimate reason justifying not informing the employee).

When documents or emails are not marked as “personal” but contain information of a personal nature, the employer may open and review the data but may not use such documents or emails to justify applying disciplinary measures to the employee or use such documents or emails as evidence in court if they indeed relate to the employee’s private life.

Special attention must be given to employee representatives who must be entirely free to carry out their duties.

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]

Interviewers, investigators, interviewees or any others involved in the investigation are often bound by a reinforced confidentiality obligation, particularly when the internal investigation is triggered by a whistleblower alert. In addition, every person that comes to know of the investigation, facts or people involved is bound by an obligation of discretion. Furthermore, investigators should specifically be trained for interviews and be reminded of their obligations relating to the investigation.

The investigators will need to determine the order of the tasks to be carried out in the investigation, as this will have a significant impact on confidentiality management. Should they start with the hearings or a review of documents? The answer may depend on the subject matter of the investigation. It is advisable to first review the documentation before organising interviews, particularly to avoid the destruction of certain documents by employees acting in bad faith or by those wishing to erase the traces of alleged wrongdoing. Sometimes, however, it is possible to start with the interviews, especially in the case of harassment, as there may be no documents to review. If the decision is taken to conduct the documentation review after the interviews, it could be useful to ask the employees involved to sign a document stating that they must preserve and retain documents, meaning that if they delete or destroy documents, they would be acting against the company and in breach of the law.

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]
