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]

Employees may be reluctant to be interviewed or act as witnesses as part of an investigation, perhaps due to fear of reprisals. The investigator should discuss any concerns with the employee and attempt to alleviate any fears.
In general terms, an employer should not compel any employee to provide a witness statement. There may be circumstances in which this could be seen as a reasonable management instruction (and any refusal to comply treated as a disciplinary matter), but these will be rare. Evidence that is compelled is unlikely to be particularly useful to the investigator.
It may be possible to establish an express or implied obligation for senior managers to report on another employee's misconduct – as a feature of either their employment contractual duties, their fiduciary duties or their implied duty of fidelity. However, it is unlikely, in the absence of an express obligation, that a junior employee would be compelled to give evidence against a colleague.
Employees who act as witnesses benefit from their usual employment protections, and must be treated as per their contractual and statutory rights, as well as any policy governing the investigation. If the investigation involves allegations which could involve discrimination, the EA 2010 extends protection from victimisation to “giving evidence or information in connection with proceedings under this Act”. Witnesses should therefore not be subject to any detrimental treatment because they have acted as a witness in this type of investigation. Witnesses may also be entitled to protection as whistleblowers if their evidence amounts to a protected disclosure (see question 9).

Legal professional privilege may attach to investigation materials if they are generated for the sole or dominant purpose of giving or obtaining legal advice (legal advice privilege); or created with the sole or dominant purpose of either obtaining or giving advice about or obtaining evidence to be used in an actual or reasonably contemplated litigation (litigation privilege).[1] Legal advice privilege applies to confidential communications between lawyers and their clients, whereas litigation privilege may extend to communications between lawyers, clients and third parties. The employer may withhold disclosure of any materials that are subject to either legal advice or litigation privilege.
In the context of a workplace investigation, internal interview records are protected by legal advice privilege if the dominant purpose of creating those records is to seek legal advice on potential disciplinary action against the employee. Such interview records are protected by litigation privilege if they are created to obtain evidence in an actual or reasonably contemplated litigation.
It should be noted that the point in time at which the sole or dominant purpose is judged is when the document is created. In other words, a document is not covered by litigation privilege if it was not created for litigation purposes but was subsequently used to obtain legal advice for litigation.[2] On a practical point, if the employer would like to minimise disclosure of the investigation by claiming privilege over relevant materials, it may wish to limit the number of documents created and persons to which they are circulated to avoid potential waiver of privilege.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).
The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]
The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

There are two limited types of privilege which may be relevant to investigations:
- Legal Advice Privilege (LAP), which protects communications between lawyers and their clients provided they are confidential and made for the dominant purpose of obtaining or giving legal advice; and
- Litigation Privilege (LP), which can extend to communications between a lawyer and client or third parties, but only where the dominant purpose of the communication is to prepare for or conduct existing or contemplated litigation.
If the relevant tests for privilege are met and apply to materials generated in the course of the investigation, the employer retains greater control over their subsequent disclosure to third parties. The materials would, for example, be protected against disclosure in any subject access request under the DPA 2018.
That said, privilege can be difficult to maintain in investigations, particularly where litigation is not active or in contemplation. Interview notes and witness statements may not attract privilege, particularly if these were conducted with employees who do not fall within the narrow definition of “the client” for LAP purposes (which is limited to employees who are capable of seeking and receiving advice on behalf of the employer).
If privilege applies to investigation materials, the investigator should keep tight control on what documents are created and how they are circulated, to avoid inadvertent disclosure and potential waiver of privilege.
Bear in mind that even if privilege applies to certain investigation materials, there may be a need to create disclosable documentation at a later stage, particularly if there is a decision to instigate disciplinary action.

It could be stressful for employees to be involved in a workplace investigation, whether as the victim, the subject of an investigation or a witness. More transparency in the process would help reduce stress. This could be achieved by providing the relevant employees with the timeline for different stages of the investigation and regular updates.
The employer may also consider providing mental health support to the employees concerned, for example in the form of counselling services or medical consultations. Where appropriate, the employer may also consider making reasonable adjustments to the employee’s workload and work schedule to facilitate his participation in the investigation.

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]

The employer needs to consider the health and wellbeing of all staff involved in the investigation, since this can be a very stressful process. The employer and investigator can assist by ensuring that all parties are aware of what is expected of them. Timings are also important; having a clear and expeditious timetable and providing updates if the timetable slips will help. Regular catch-ups by managers can be used to monitor how employees are coping. They should be reminded about any resources to help support them, such as employee helplines or employee assistance programmes.
Where an employer has particular concerns about an employee’s health, a referral to occupational health can assist. The employer may also wish to consider whether employees should be given additional time off, or whether any other adjustments can be made to the investigation process. For particularly serious allegations, the employer may consider facilitating the provision of independent legal advice for the employee, or making a contribution towards legal fees.
