Workplace Investigations
Contributing Editors
Workplace investigations are growing in number, size and complexity. Employers are under greater scrutiny as of the importance of ESG rises. Regulated industries such as finance, healthcare and legal face additional hurdles, but public scrutiny of businesses and how they treat their people across the board has never been higher. Conducting a fair and thorough workplace investigation is therefore critical to the optimal operation, governance and legal exposure of every business.
IEL’s Guide to Workplace Investigations examines key issues that organisations need to consider as they initiate, conduct and conclude investigations in 29 major jurisdictions around the world.

While there are no laws to compel co-workers to act as witnesses, the company may have internal policies (eg, rules of employment, code of conduct) that require employees to cooperate with company actions such as a workplace investigation. That said, it would be difficult to enforce such policies even if the employee refuses to cooperate (eg, taking disciplinary action against an employee who refuses to act as a witness).
There may be instances when the company is required to provide certain legal protection to employees acting as witnesses in an investigation. For example, if a whistleblower falling under the WPA is required to act as a witness, they would be entitled to legal protections as discussed in question 1. The company may also have internal policies that provide protection to employees acting as witnesses in an investigation.

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]

There are no provisions in Vietnamese law that impose any statutory or legal obligation on an employee to act as a witness in an investigation. Hence, an employer does not have the power to compel its employees to act as witnesses in an investigation. However, a request for an employee to provide evidence or give details of an event that he or she knows of may reasonably be deemed to be a lawful and reasonable directive from an employer. Consequently, an employee’s refusal to act as a witness may be tantamount to an act of insubordination, which may lead to disciplinary action by the employer. In any circumstances, if an employee refuses to attend an interview or is generally not cooperating with an investigation, the reasons for this will need to be considered carefully by the employer.

There is no obligation to stay the workplace investigation while the parallel criminal or regulatory investigation is being conducted. In practice, companies often proceed with, or even accelerate, the workplace investigation to find out the facts and defend themselves against the parallel criminal or regulatory investigation being conducted. The company should be careful not to engage in activities that may raise suspicions as to whether the company is impeding the government investigation or concealing or destroying evidence.
While the investigation report would typically not be privileged, the company may consider explaining to the authorities that the investigation findings are not conclusive, should the police or regulator request the internal investigation report.

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).

There are no issues with an internal workplace investigation being conducted in parallel to any criminal or regulatory investigation. In such a case, the employer should handle the workplace investigation meticulously, pay attention to all the facts and evidence, inform the authorities of the ongoing internal workplace investigation, and ensure that it complies with all applicable legal requirements or directions made by the relevant authorities concurrently. Also, the employer should not take any steps that interfere with, hinder, or obstruct the parallel investigations.

As mentioned in question 19, employees may potentially raise claims, such as that the company violated data privacy laws in reviewing employee data, committed defamation, coerced the employee to comply with the investigation, and that witnesses or the company committed defamation in violation of the Criminal Code or disciplined the employee without just cause.

As there are no specific regulations for internal investigations, the usual legal framework within which the employer must act towards the employee derives from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights.
But, for example, unwarranted surveillance could conceivably result in criminal liability (article 179 et seq, Swiss Criminal Code) for violations of the employee's privacy. Furthermore, errors made by the employer could have an impact on any later criminal proceedings (eg, in the form of prohibitions on the use of evidence).[1]
Evidence obtained unlawfully may only be used in civil proceedings if there is an overriding interest in establishing the truth (article 152 paragraph 2, Swiss Civil Procedure Code). Consequently, in each case, a balance must be struck between the individual’s interest in not using the evidence and in establishing the truth.[2] The question of the admissibility of evidence based on an unlawful invasion of privacy is a sensitive one – admissibility in this case is likely to be accepted only with restraint.[3] Since the parties in civil proceedings do not have any means of coercion at their disposal, it is not necessary, in contrast to criminal proceedings, to examine whether the evidence could also have been obtained by legal means.[4]
Unlawful action by the employer may also have consequences on future criminal proceedings: The prohibitions on exploitation (article 140 et seq, Swiss Criminal Procedure Code) apply a priori only to evidence obtained directly from public authorities. Evidence obtained unlawfully by private persons (ie, the employer) may also be used if it could have been lawfully obtained by the authority and if the interest in establishing the truth outweighs the interest of the individual in not using the evidence.[5] Art. 140 paragraph 1 Swiss Criminal Procure Code remains reserved: Evidence obtained in violation of Art. 140 paragraph 1 Swiss Criminal Procure Code is subject to an absolute ban on the use of evidence (e.g. evidence obtained under the use of torture[6]).[7]

The employer may be exposed to legal action for its failure to conduct the investigation properly, such as a lawsuit for labour disputes or sanctions for its failure to protect personal data as required under personal data protection regulations. For instance, if there were errors during the investigation which led to erroneous results for the investigation and consequently, the employee was dismissed, the employee may file a claim for illegal dismissal against the employer.
