Workplace Investigations

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.
