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.

Under Hong Kong law, the employee has an implied duty to obey lawful instructions from his or her employer and to serve the employer with fidelity and good faith during the term of his or her employment. A lawful instruction from an employer may include a reasonable request for the employee to participate and provide information in the workplace investigation. If the employee refuses to comply with such instruction or is obstructive or provides untrue or misleading information, it could constitute a ground for summary dismissal under the EO and at common law.
That said, in general terms, an employer should not compel any employee to testify against a co-worker, particularly if such a co-worker is a senior colleague, as evidence provided under compulsion may not be helpful to the investigation.
Employees who act as witnesses must be treated as per their contractual and statutory rights, including the right against self-incrimination. If the investigation involves allegations of discrimination on the ground of sex, race or disability, the employer should ensure that the witnesses will not be victimised or treated less favourably than other employees.

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 legal requirement in Hong Kong on this. However, since the investigation records will likely contain personal data, employers should be mindful of the requirement under the PDPO that personal data should not be kept for longer than necessary.[1]
According to the Code of Practice on Human Resources Management published by the Privacy Commissioner for Personal Data, generally, employment data about an employee can be kept for the entire duration of his or her employment, plus a recommended period of no more than seven years after the employee leaves employment unless there is a subsisting reason that justifies a longer retention period. A longer retention period may be justified where there is ongoing litigation or a parallel investigation. Even where it is deemed necessary to retain the outcome of the investigation concerning a departed employee, the employer should ensure that other personal data on the employee’s record (that is unrelated to the purpose of retention) are erased after the expiry of the recommended retention period.

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]

Vietnamese law does not provide for a period during which the outcome of the investigation should remain on the employee’s records and files. However, this will depend on the employer’s record-retention policies, which must comply with applicable data protection laws.

If the employer failed to comply with a requirement that is expressly stipulated in the employment contract or employee handbook (such as a procedural requirement to hold a disciplinary hearing or to provide certain information to the employee), the employer could be liable for breaching an express term in the employment contract.
Even where the employment contract does not contain express provisions for the conduct of an internal investigation, the employer is under an implied obligation of trust and confidence under common law (as discussed in question 11), which requires it to conduct the investigation and reach its findings reasonably and rationally in accordance with the evidence available and in good faith.[1] If the employer reached a decision that no reasonable employer would have reached, the conduct of the investigation may be in breach of the employer’s implied obligation of trust and confidence.
If the error in the investigation has led to a termination of employment (whether by way of summary dismissal or termination by notice), the employee may be able to bring a statutory claim for wrongful dismissal, unlawful dismissal or dismissal without a valid reason (as applicable).[2] If such a claim is successful, in addition to ordering the employer to pay monetary compensation, the court or tribunal may also make a reinstatement order (an order that the employee shall be treated as if he had not been dismissed) or re-engagement order (an order that the employee shall be re-engaged in employment on terms comparable to his or her original terms of employment) for the affected employee.
The employer may also be liable for unlawful discrimination under Hong Kong law if the investigation has been conducted in a discriminatory manner or the outcome of the investigation reflects differential and less favourable treatment of the employee concerned based on grounds of sex, marital status, disability, family status or race.

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.
