Workplace Investigations

An essential part of an internal investigation is the questioning of employees. Their statements contribute significantly to clarifying possible violations. In particular, the legal principles that apply to criminal proceedings, including the right to refuse to testify, do not apply directly to internal investigations.

Employees do not legally have to participate in such interviews. Their duty to cooperate arises indirectly from other legal provisions, in particular from employees’ duties of loyalty and service under labour law.

Austrian law suggests there is a general principle of loyalty, which triggers a “duty to inform” under some circumstances; in principle, the employee and any witnesses are expected to provide information in the context of internal investigations. While the employee is not compelled to incriminate him or herself, he or she also may not withhold work-related information that the employer legitimately wishes to protect, for the sole reason that it might incriminate him or her. The decision as to whether the employee must disclose information depends on a balancing of interests in the specific case.

Investigators and employers must strictly adhere to the permissible limits. This requires compliance with labour law, criminal law and data protection law.

Employees cannot be compelled to act as witnesses. Employers may have trouble enforcing internal policies stating that employees who refuse to participate in investigations will be disciplined (warned, suspended or have their contract terminated for cause), but can terminate their contract without cause.

There are no explicit legal protections for employees acting as witnesses, but it is common best practice to have witnesses’ identities protected to the extent necessary for the investigation, and to protect them from retaliation.

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.

The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

All data processing must comply with the principles of article 5 GDPR (lawfulness, fairness, transparency, purpose limitation, data minimisation, accuracy, storage limitation and integrity). Personal data may only be collected and processed for specific, lawful purposes.

The admissibility of data processing depends on whether the suspicion relates to a criminal offence or another violation of the law. If the data processing is relevant to criminal law, article 10 GDPR or section 4(3) of the Austrian Data Protection Act (DSG) applies. If the investigations are exclusively to clarify violations under civil or labour law, such as an assertion of claims for damages or if they are general investigations to establish a criminal offence, the permissibility of data processing is based on article 6 or, for data covered by article 9 GDPR, on this provision.

The Brazilian General Data Protection Law (LGPD) does not have specific rules or principles that apply to internal investigations conducted within private organisations. Despite that, the general principles and obligations set forth by the LGPD apply to any processing of personal data carried out within the context of such investigations. As a result, the company must ensure the transparency of such processing activities through a privacy notice addressed to the data subjects; only process the personal data that is necessary for the investigation; define the lawful basis that applies to such processing activities (especially for sensitive data); and apply any other obligations established by the LGPD.

The Swiss Federal Act on Data Protection applies to the gathering of evidence, in particular such collection must be lawful, transparent, reasonable and in good faith, and data security must be preserved.[1]

It can be derived from the duty to disclose and hand over benefits received and work produced (article 321b, Swiss Code of Obligations) as they belong to the employer.[2] The employer is, therefore, generally entitled to collect and process data connected with the end product of any work completely by an employee and associated with their business. However, it is prohibited by the Swiss Criminal Code to open a sealed document or consignment to gain knowledge of its contents without being authorised to do so (article 179 et seq, Swiss Criminal Code). Anyone who disseminates or makes use of information of which he or she has obtained knowledge by opening a sealed document or mailing not intended for him or her may become criminally liable (article 179 paragraph 1, Swiss Criminal Code).

It is advisable to state in internal regulations that the workplace might be searched as part of an internal investigation and in compliance with all applicable data protection rules if this is necessary as part of the investigation.

There is no additional support for the employees concerned. However, the employer may offer support measures to the employees to ensure better cooperation. The choice of support measures is at the employer's discretion. For example, the employer could offer to bear lawyer’s fees, if the employee is cooperative. Such decisions must always be made on a case-by-case basis.

It is highly recommended that investigation interviews are conducted in the interviewed person’s native language, even if the individual speaks the language used for business within the company, to ensure that there is no miscommunication or loss of accuracy in the determination of the facts. Also, speaking their native tongue reduces the discomfort of participating in the interview and potential extra work due to post-interview correction or confirmation. Depending on the scope of the investigation, the company can have attorneys who speak both the individual’s language and the company’s business language conducting interviews.

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[2]
