Workplace Investigations

Typical triggers for a workplace investigation may be internal hints (eg, from employees), internal audits, compliance or the legal department. However, investigations by the public prosecutor or other authorities can also lead to a workplace investigation.

There are no strict guidelines for the course of the investigation. The measures to be taken and the sequence in which they will be carried out to clarify the facts must be decided on a case-by-case basis. However, the first step should be to secure evidence. All relevant documents and records (eg, e-mails, hard disks, text messages, data carriers, copies) should be collected and employees may be interviewed. The second step should be to evaluate the evidence and the third step is to decide how to deal with the results (eg, whether any disciplinary measures should be taken or the intended procedures should be adjusted).

Irrespective of how a workplace investigation is commenced, when it comes to severe breaches of duty by an employee, a two-week exclusion period for issuing a termination for cause must be observed at all stages. This two-week period starts when the employer becomes aware of the relevant facts but is suspended as long as the employer is still investigating and collecting information, provided that the investigation is carried out swiftly.

The circumstances in which an employer commences a workplace investigation may vary. However, it is common that an employer will consider it necessary to commence a workplace investigation upon receipt of a complaint concerning a fellow employee. Sometimes, the complaint may be made anonymously. If the employer considers there to be substance in the complaint, it may commence an investigation to find out the truth of the matter, resolve the complaint and, if necessary, improve its systems and controls to prevent the reoccurrence of any misconduct.

A workplace investigation may be warranted if the employer receives an enquiry from a regulator concerning its affairs or an employee’s conduct. The investigation findings could enable the employer to respond to the regulator (which could be a mandatory obligation) and at the same time assess its risk exposure.

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]

Since there is no mandatory law (yet) that provides a framework for workplace investigation interviews, there are also no special protective regulations for employees acting as witnesses.

Employees have a contractual duty to participate in interviews – be it as a suspect or as a witness – as part of workplace investigations. The employee must provide truthful information based on his duty of loyalty if:

• the questions relate to his area of work;
• the employer has an interest worthy of protection in obtaining the information; and
• the requested information does not represent an excessive burden for the employee.

Whether such a burden can be assumed when the employee must make statements by which he may incriminate himself is disputed in German case law and legal literature. The German Federal Labour Court has not yet decided on this question. Since an internal workplace investigation interview is an interview under private law and not under criminal law, there are, in our view, good arguments that the employee must also make a true statement even if he incriminates himself, provided his area of work is concerned. However, some labour courts assume that in these cases such a statement could not be used in criminal proceedings.

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]

Depending on the subject of the investigation and the severity and significance of the suspected violation, employees who are involved in the workplace investigation may already have to maintain confidentiality based on their contractual duties. The prerequisite for this is that the employer has a legitimate interest in maintaining confidentiality. Criminal acts are not subject to confidentiality, but there is also no general obligation for the employee to report or disclose a criminal act to the authorities or the public prosecutor. However, reporting to the competent authorities may be required in certain cases (see question 25).

Lawyers are bound by professional confidentiality and are generally not allowed to provide information about any information they receive from their clients. An exception exists, for example, if the lawyer must provide information to defend himself in court proceedings. There is also no absolute protection against the seizure of documents at an attorney’s office (see question 14).

Workplace investigations should usually be conducted on a confidential basis to preserve the integrity of the investigation, avoid cross-contamination of evidence and maintain the confidentiality of the employee under investigation. This means that those involved in the investigation (ie, the subject employee and any material witnesses) should be made aware of the fact and substance of the investigation on a need-to-know basis.

While the extent of the confidentiality obligations are usually governed by the employer’s internal policies and the employment contract, there are circumstances where the employer has a statutory duty to keep information unearthed in the investigation confidential. For instance, if it is found that certain property represents proceeds of an indictable offence[1] or drug trafficking[2], or is terrorist property[3], the employer should report its knowledge or suspicion to the Joint Financial Intelligence Unit (JFIU) as soon as is reasonably practicable and avoid disclosure to any other person as such disclosure may constitute “tipping off”. Another example is if a workplace investigation is commenced in response to a regulatory enquiry, the employer may be bound by a statutory secrecy obligation and may not be at liberty to disclose anything about the regulatory enquiry to anyone including those who are subject to the workplace investigation. For example, section 378 of the Securities and Futures Ordinance (SFO) imposes such a secrecy obligation on anyone who is under investigation or assists the Securities and Futures Commission (SFC) in an investigation.[4]

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]
