Workplace Investigations

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]

In general, except as provided above, depending on the seriousness of the complaint and investigation, the only persons who should be aware of it are the relevant individual in human resources or legal, and where different, the persons assigned to investigate. Although it may not be feasible to maintain absolute confidentiality in conducting an investigation depending on the nature of the allegations, investigators should exercise discretion at all times and, where possible, avoid identifying complainants, the subject of the investigation or witnesses by name where it is not necessary, and where doing so could be detrimental to the fact-finding process.

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.

For legal privilege to apply, a primary purpose of the investigation should be to provide legal advice to the company, including concerning non-lawyers working at the counsel’s direction, and legal privilege likely will not apply to internal investigations performed as part of the ordinary course of business or where the investigation is required by a state or federal regulatory regime (eg, post-incident investigations of operations governed by OSHA’s Process Safety Management Standards). It is, therefore, important to contemporaneously document the scope and purpose of the investigation and not risk waiving privilege by sharing privileged materials with unnecessary third parties.

Whereas attorney-client privilege includes only communications between an attorney and the client, work-product privilege is broader and includes materials prepared or collected by persons other than the attorney with an eye towards impending litigation. Examples of potential work products produced by attorneys in the context of an investigation include investigative work plans, interview outlines, memoranda summarising witness interviews and investigative reports.

As a practical matter, employees should be aware that communications with other employees or colleagues regarding the investigation are not privileged regardless of whether the colleague is also involved in the investigation or represented by the same counsel. Even if an employee believes he or she is sharing attorney communications with other employees who need to know the attorney’s advice and who also have attorney-client privilege with the same counsel because he or she is involved or implicated in the investigation and also represented by company counsel, it is always prudent to refrain from sharing privileged information. If an attorney’s communication is shared beyond those who need to know, attorney-client privilege may be destroyed.
