Workplace Investigations

Attorney-client privilege will apply to all communication and investigative material between a client and its law firm. Attorney-client privilege is, however, not without limitations. Regarding investigations into alleged employee misconduct, a law firm may have to report suspected money laundering to the authorities and under certain circumstances disclose information to the financial police.

Written material covered by attorney-client privilege generally may not be seized.

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.

Handling a parallel investigation will have to be assessed on a case-by-case basis depending on the applicable rules. For instance, an investigation under the Swedish Discrimination Act is subject to certain timing requirements with which the employer must comply. In other cases, it may be more appropriate to hold off the workplace investigation while awaiting the outcome of the parallel investigation.

The police or regulator can, depending on the matter at hand, request an employer to share evidence. The police or the regulator may also, under certain circumstances, retain evidence in a search.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).

Under the GDPR personal data may not, according to the general principle on storage limitation, be retained for longer than is necessary for the purposes for which the personal data are processed. The GDPR does not stipulate a generally applicable storage limitation period. Such a regulation is, on the other hand, included in the Swedish Whistleblowing Act. If the Swedish Whistleblowing Act applies, the outcome of the investigation and all personal data should be retained for as long as necessary, but not for longer than two years after the investigation has been closed.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]
