Workplace Investigations

In general, an internal investigation is only initiated if there is suspicion of a violation. The decision to commence an internal investigation is up to the company, and it has to weigh the pros and cons. For limited liability companies, which are subject to the Association Responsibility Act, an internal investigation may exempt them from criminal liability. Disadvantages may include investigation costs, disruption of operations, discovery of information requiring later disclosure, possible negative media coverage and increased risk of exposure to external parties.

Investigations can relate to specific individuals, departments, or the entire company. An investigation may include various measures, such as obtaining and analysing files and documents, conducting questionnaires and employee interviews, monitoring internet use, video or telephone surveillance of employees and setting up whistleblowing hotlines. Not all measures are acceptable without restrictions. The provisions of labour law and data protection law must always be complied with.

To avoid wasting resources, the objectives of the investigation should be defined in advance. In addition, the selection and sequence of instruments to be used should be determined. A legal assessment of the chosen measures is essential to avoid legal complications.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

The employer should determine the intended recipients and format of the report in advance. In many cases, it may be advisable to publish only the results of the investigation to protect the privacy and reputation of the individuals concerned, as this may help to minimise any potential negative impact on them.

However, under certain circumstances or due to legal requirements, full disclosure of the investigation report may be required, especially if transparency and disclosure are necessary to maintain public or investor confidence.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

Data protection law requires that personal data should not be kept longer than necessary for the purpose it was collected. Once the purpose of the internal investigation is fulfilled and the data is no longer needed, it should be deleted or anonymised. Regulations regarding this matter may also be subject to WCAs or internal policies. In any case, it is advisable to keep the results for as long as they may be needed in possible subsequent administrative or judicial proceedings.

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]
