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.

Interviewing co-workers is often conducted in internal investigations. Company employees are generally required to cooperate with company investigations, especially those who are in a position to instruct and supervise employees, or those who are responsible for maintaining corporate order, since cooperation with an investigation is itself the fulfilment of their duty to the company. Other employees are not compelled to cooperate with such an investigation unless it is deemed necessary and reasonable. No specific legal protection is provided for testifying in an investigation.

Singapore law does not impose any statutory or legal obligation on an employee to act as a witness in the investigation. Accordingly, an employer does not have the power to compel its employees to act as witnesses in an investigation.
Notwithstanding this, an employer may require an employee to assist in investigations pursuant to specific contractual obligations in the employee’s terms of employment (as may be contained in the employment contract, employee handbook or the employer’s internal policies and procedures in dealing with the investigations, etc). Further, a request for an employee to provide evidence 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 amount to an act of insubordination that may attract disciplinary action by the employer.
Employers requiring employees to act as witnesses in an investigation must ensure that they comply with the expectations and norms set out by the Tripartite Guidelines on Fair Employment Practices and the TAFEP Grievance Handling Handbook.

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]

Since inspections of personal belongings may potentially undermine employees' fundamental human rights, they would not become lawful simply because they are conducted under employment regulations.
Inspections of personal belongings must be conducted uniformly among employees in the workplace based on reasonable grounds, in a generally reasonable manner and to a generally reasonable degree, and based on the work rules, etc.
When inspections of personal belongings are conducted under employment regulations, etc, employees must agree to the inspection except in special circumstances, such as the method or degree of the inspection being unreasonable.
On the other hand, an investigation of information stored on a company network system may constitute an infringement of the right to privacy. If there is a provision in the employment regulations regarding the use of the internet and monitoring, it is possible to investigate under such a provision. A Japanese court case on the illegality of reading e-mails in the absence of a monitoring provision stated that private use of e-mails also carries a certain right to privacy, but also stated that "considering the fact that the system is maintained and managed by the company, the protection of the employee's privacy can only be expected within a reasonable range according to the specific circumstances of the system," and that the act of reading e-mails was not illegal because the extent of private use of e-mails was beyond the limit, which was outside the reasonable range of socially accepted ideas. The court also ruled that the monitoring of the employee's abusive private use of e-mail, which was discovered in the course of an investigation of slanderous e-mails within the company, was not illegal because even if the monitoring was conducted without notice, there was suspicion of a violation of the duty of devotion to duty and corporate order. The court also stated that the investigation was necessary and that the scope of the investigation did not exceed its limit.

The employer is not allowed to search employees’ personal possessions or files as part of an investigation without the employee’s consent. However, such consent may be explicitly provided for in the terms of employment (as may be contained in the employment contract, employee handbook or the employer’s internal policies and procedures in dealing with the investigations, etc). The employer may, however, search the employees’ company email accounts and files if these are stored on the company’s internal systems or devices.

The basic rule is that the employer may not search private data during internal investigations.
If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

See question 9 for the confidentiality obligations of a whistleblower response service employee.
Other than the above, there is no specific legal obligation to maintain confidentiality for persons in charge of investigations, etc. However, if the information falls under the category of confidential information obtained by employees in the course of their work, compliance is required as an obligation attached to a labour contract, and many employment regulations stipulate a duty to keep information obtained in the course of work confidential.

The existence and scope of any confidentiality obligations would generally depend on the specific terms of the employment contract, employee handbook or the employer’s internal policies and procedures in dealing with the investigations.
In the context of investigations into workplace harassment issues, the Tripartite Advisory on Managing Workplace Harassment issued by the MOM provides that the identities of the alleged harasser, affected persons and the informant should be protected unless the employer assesses that disclosure is necessary for safety reasons.
This may change with the enactment of the Workplace Fairness Legislation referred to in question 1. The Tripartite Committee on Workplace Fairness recommended, among other things, that employers should protect the confidentiality of the identity of persons who report workplace discrimination and harassment, where possible. As such, it is expected that the upcoming Workplace Fairness Legislation may impose certain confidentiality obligations on an employer during an investigation.

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]
