Workplace Investigations

Evidence obtained in the context of an investigation must specify who provided it and the date it was provided. No retaliatory measures may be taken against the whistleblower for the act of whistleblowing.

In certain cases, the whistleblower report must be forwarded to the judicial authorities (eg, when there is an obligation to assist persons in imminent danger, for serious offences or a disclosure that a vulnerable person is in danger (ie, minors under 15 or a person who is unable to protect themselves)).

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

Several federal, state, and local employment laws prohibit retaliation against employees who come forward with complaints or participate in corporate investigations. Employees who possess information regarding corporate misconduct may also be considered whistleblowers protected from retaliation under federal and state whistleblower laws, including but not limited to the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the Consumer Financial Protection Act of 2010.

An employee generally does not need to show that he or she was terminated or demoted to bring a retaliation claim; other actions on the part of the employer may qualify if they could be seen to discourage employees from raising complaints. To protect against a potential retaliation claim, employers should make clear at the outset of an investigation that retaliation will not be tolerated and require the complaining employee (and potentially his or her manager) to bring any instances of retaliation to the investigator’s attention immediately.

If the outcome of the internal investigation has led to the sanctioning of an employee, this sanction may no longer be invoked to support a new sanction after three years. Moreover, under the GDPR principles, the duration of retention must be proportional to the use of the data. Therefore, the data must be retained only for a period that is “strictly necessary and proportionate”. If the employer wants to keep information about the investigation in the longer term, it is possible to archive the employee’s record even though the employer will no longer be able to use it against the employee after three years.

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]

There is no requirement for the results of a workplace investigation to remain on an employee’s record for any specific period. It is often helpful, however, for information relating to the outcome of such an investigation (regardless of whether the allegations are substantiated) to be accessible to the human resources or legal functions such that during the initial complaint intake process described above, any prior complaints and investigations relating to the same individual or group of individuals can be taken into account to identify any recurring issues or systemic violations.
