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]

When dealing with reports and persons covered by the HSchG, the provisions on identity protection must be followed. In all internal investigations, only authorised persons should receive information.

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]

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]
