Workplace Investigations

Employees cannot be forced by their employer to act as a witness. If they decide to nonetheless testify as a witness, they do not, in principle, have particular rights. If the employee puts himself in a difficult or even dangerous position to act as a witness, it is up to the employer to offer the necessary protection or take measures to prevent any harm (eg, by keeping the identity of the witness confidential or by planning the hearing at a place or time when the employees involved are not aware of it).  

However, this is not the case for whistleblowing reports, where a witness might be seen as a “facilitator” who can receive protection against any retaliation by the employer.

Also, workers who were direct witnesses to official allegations of sexual harassment, violence or bullying at work are protected against retaliation by the employer. This also applies to witnesses in court.

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]

Here, the investigation “collides” with the right to privacy of the persons involved.

First, the rules and principles of the GDPR will apply if personal data is involved. Therefore, the employer will have to find a data-processing ground, which could be his or her legitimate interest or the fact that the investigation could lead to legal proceedings, etc. The data processing should also be limited to what is proportionate and the data subjects should be informed. Due to this obligation, it is arguable that the GDPR policy already provides the necessary information for the employees not to jeopardise the investigation. In any case, data subjects should not be able to use their right to access data to ascertain the preliminary findings of the investigation (which are confidential) or any confidential identities involved (eg, in the whistleblower procedure, the identity of the report should be protected at all times).

Also, the employer should follow the procedure of Collective Bargaining Agreement No. 81 on searching the e-mails or computer files and internet searches of employees. This CBA limits the purposes for searches and lays down a double-phase procedure that needs to be followed if private data is involved. Next to this, the employer should also take into account the case law of the European Court of Human Rights, which only allows e-mail and computer searches based on the following:

• whether the employee has been notified of the possibility that the employer might take measures to monitor correspondence and the implementation of such measures;
• the extent of the monitoring and the degree of intrusion into the employee’s privacy (including a distinction between the monitoring of the flow or the content of the communications);
• whether the employer has provided legitimate reasons to justify monitoring of the communications and accessing of their actual content; and
• whether it would have been possible to establish a monitoring system based on less intrusive measures, the consequences of the monitoring for the employee who is subject to it, and whether the employee had been provided with adequate safeguards.

Next, if the employer wants to use camera images, the rules of Collective Bargaining Agreement No. 68 should have been followed when installing cameras. If not, the images might have been collected illegally.

If physical evidence contains data relating to an individual, from which the identity of the individual can be ascertained,[1] the data would constitute personal data under the Personal Data (Privacy) Ordinance (Cap. 486) (PDPO). The PDPO sets out several data protection principles that the employer must comply with while processing personal data, including:[2]

• personal data must be collected for a lawful purpose related to a function or activity of the employer and should not be excessive for this purpose. An internal investigation would be regarded as a lawful purpose;
• personal data must be accurate and not kept longer than is necessary;
• personal data must not be used for a purpose other than the internal investigation (or other purposes for which the data was collected) unless the employee consents to a new use or the new use falls within one of the exceptions provided in the PDPO;
• personal data must be safeguarded against unauthorised or accidental access, processing or loss; and
• the employee whose personal data has been collected has the right to request access to and correction of his or her personal data retained by the employer.

If an employer wants to gather evidence through employee monitoring, it should ensure that the act of monitoring complies with the data protection principles of the PDPO if the monitoring activity would amount to the collection of personal data. The Privacy Commissioner for Personal Data has issued guidelines to employers on the steps they can take in assessing whether employee monitoring is appropriate for their businesses.[3] As a general rule, employee monitoring should be conducted overtly. Further, those who may be affected should be notified in advance of the purposes the monitoring is intended to serve, the circumstances in which the system will be activated, what personal data (if any) will be collected and how the personal data will be used.

Covert surveillance of employees should not be adopted unless it is justified by relevant special circumstances. Employers should consider whether there is reason to believe that there is an unlawful activity taking place and the use of overt monitoring would likely prejudice the detection or collection of evidence.[4] Even if covert monitoring is justified, it should target only those areas in which an unlawful activity is likely to take place and be implemented for a limited duration of time.

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.

If the investigation leads to the establishment of grave errors by the employee, this can lead to sanctions. The employer must follow the procedure laid down in the internal work rules of the company and can only impose sanctions that are included in the internal work rules. In general, these are: a verbal warning; a written warning; a suspension (remunerated or not); a fine (capped to one-fifth of daily remuneration); and dismissal. If there are very serious errors leading to an immediate inability to continue the employment relationship with the employee, the employer can dismiss the employee with urgent cause without any notice period or indemnity in lieu of notice (following the specific procedure for these types of dismissals). In less serious cases, the employer could still dismiss the employee with a notice period or indemnity in lieu of notice. In principle, the employer has a right to dismiss the employee, even if this sanction is not included in the internal work rules.

As said previously, disciplinary sanctions (included in the internal work rules) must be communicated to the sanctioned employee the day after the employer or his delegate has established fault. The sanction must be registered in a sanction register, with the name of the employee, the date, the reason and the nature of the sanction. If there is a fine, the amount of the fine should be mentioned. The proceeds of the fines must be used for the benefit of employees. Where a works council exists, the use of the proceeds of the fines must be determined after consultation with it.

If the outcome of the investigation reveals that misconduct has been committed by the employee, the employer may consider whether it should allow the employee to defend him or herself against such findings. If the employment contract or relevant internal policies specify a right to be heard on the part of the employee through a disciplinary hearing before any actions can be taken against him or her, such procedures should be followed.

Assuming the employer maintains its findings that the employee has committed misconduct after the conclusion of the disciplinary hearing (if any), the employer may consider taking one of the following disciplinary actions against the employee depending on the nature and severity of the misconduct:

• Verbal or written warning – this is a common form of disciplinary action. The employer may consider including the nature of the misconduct and the potential consequences of repeating such misconduct (for example, termination of employment) in the warning to be given to the employee;
• Termination with notice – the EO allows employers and employees to terminate the employment with notice. It is not necessary to give reasons for the termination unless the employee concerned has been employed for at least 24 months, in which case the employer shall demonstrate a valid reason for the termination as defined under the EO;
• Suspension – the employer may suspend the employee without pay for up to 14 days in circumstances where the misconduct concerned justifies a summary dismissal, or where a decision on summary dismissal is pending. The employee may also be suspended where there is a criminal proceeding against him or her relevant to the investigation, until the conclusion of the criminal proceeding (as discussed in question 3);[1] and
• Summary dismissal – the employer may terminate an employment contract without notice if the employee is found to have:
  • wilfully disobeyed a lawful and reasonable order;
  • failed to duly and faithfully discharge his duties;
  • committed fraud or acted dishonesty; or
  • been habitually neglectful in his duties.[2]

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.
