Workplace Investigations

Mainly, the Occupational Safety and Health Act (738/2002). In addition, the following also have relevance in connection to a workplace investigation: the Employment Contracts Act (55/2001), the Criminal Code (39/1889), the Act on Occupational Safety and Health Enforcement and Cooperation on Occupational Safety and Health at Workplaces (44/2006), the Act on Equality between Women and Men (609/1986) and the Non-discrimination Act (1325/2014). In addition, the employer's own policies must be taken into consideration while conducting a workplace investigation.

A workplace investigation is usually governed by the employer’s internal grievance policy or contractual guidelines found in the employment contract or employee handbook. In the absence of the same, the default governing regime is as set out by the Ministry of Manpower (MOM) and the Tripartite Alliance for Fair and Progressive Employment Practices (TAFEP) in its guidelines and advisories, which include:

• the Tripartite Advisory on Managing Workplace Harassment;
• the TAFEP Grievance Handling Handbook; and
• the Tripartite Guidelines on Fair Employment Practices.

In addition, section 14(1) of the Employment Act 1968 provides that an employer is required to conduct “due inquiry” before dismissing an employee covered under the Employment Act 1968 without notice for misconduct. The Singapore Courts take the view that “due inquiry” suggests some sort of process in which the employee concerned is informed about the allegations and the evidence against him or her so that he or she has an opportunity to defend him or herself with or without evidence during the investigation process.

Further, there are numerous cases where the Singapore High Court has alluded to or implicitly accepted the application of the implied term of mutual trust and confidence in employment contracts that would oblige the employer to act reasonably and fairly during the investigation, even though it is worth noting that the Singapore Court of Appeal has stated that the status of the implied term of mutual trust and confidence has not been settled in Singapore and that the Appellate Division of the Singapore High Court has stated that “[i]t remains an open question for the Court of Appeal to resolve in a more appropriate case, ideally with facts capable of bearing out a claim based directly on the existence of the implied term” (see [81]-[82] of Dong Wei v Shell Eastern Trading (Pte) Ltd and another [2022] SGHC(A) 8).

Hence, any references to the application of the implied term of mutual trust and confidence in Singapore in this article must be read in light of the above.

The current position is expected to change in the second half of 2024, with the passing of Singapore’s first workplace fairness law, the Workplace Fairness Legislation. On 4 August 2023, the Singapore government announced that it has accepted the final set of recommendations by the Tripartite Committee on Workplace Fairness in respect of the upcoming Workplace Fairness Legislation. The Tripartite Committee on Workplace Fairness recommended, among other things, that employers are required to put grievance-handling processes in place. It is therefore expected that the Workplace Fairness Legislation may contain requirements on how and when a workplace investigation should be conducted.

This article sets out the current position, before the Workplace Fairness Legislation was enacted, and will be updated when appropriate.

When the employer becomes aware of possible misconduct, the employer must commence an investigation immediately, in practice within about two weeks. The information may come to the employer's knowledge via, for example, the employer's own observations, from the complainant or their colleagues or an employee representative.

A workplace investigation usually commences with the receipt of feedback, a complaint or a grievance, by named or anonymous persons, in respect of a work-related matter or event, or the conduct of an employee.

There is no legislation on temporary suspension in the event of a workplace investigation or similar. In some situations, the employer may relieve the employee from their working obligation with pay for a short period.

Yes. Section 14(1) read with 14(8) of the Employment Act 1968 provides that an employee can be suspended during a workplace investigation

However, pursuant to section 14(8) of the Employment Act 1968, the employer:

• may suspend the employee from work for:
  • a period not exceeding one week; or
  • such longer period as the Commissioner for Labour may determine on an application by the employer; but
• must pay the employee at least half the employee’s salary during the period the employee is suspended from work.

Section 14(9) of the Employment Act 1968 further states that if the inquiry does not disclose any misconduct on the employee’s part, the employer must immediately restore to the employee the full amount of the withheld salary.

In addition to the above legislative requirements, the company is required to also comply with its policies relating to such suspensions.

In terms of the threshold to be crossed before a suspension can take place, the Singapore Courts have highlighted that suspending an employee quickly as part of a “knee-jerk” reaction to an unclear or unspecific allegation with dubious credibility is arguably a breach of the implied term of mutual trust and confidence that exists in all employment relationships ([56] of Dong Wei v Shell Eastern Trading (Pte) Ltd and another [2021] SGHC 123). The employer would need to have proper and reasonable cause to suspend an employee for disciplinary purposes ([56(d)] of Cheah Peng Hock v Luzhou Bio-Chem Technology Ltd [2013] 2 SLR 577; [2013] SGHC 32), for example, where multiple credible sources claimed that they had been sexually harassed by an employee, and the employer had strong grounds to believe that if the employee was not suspended, the safety and wellbeing of the other employees in the organisation would be threatened.

In contrast, an employer is not entitled to suspend an employee during a workplace investigation where the employer has only received one complaint that has not been properly described or substantiated with sufficient details from an unverified or unreliable source against an employee who has a good track record with the organisation. This is especially so if the complaint is so unclear that further inquiries should be made before the allegation can be properly ascertained and characterised (see also [51] of Dong Wei v Shell Eastern Trading (Pte) Ltd and another [2021] SGHC 123).

The employer must conduct the investigation, but the actual work can be done either by the employer's personnel or by an external investigator, for example, a law firm. Either way, there are no formal criteria for the persons executing the investigation; however, impartiality is required from the person conducting the investigation

While there are no prescribed minimum qualifications or criteria that need to be met for any person conducting a workplace investigation, the person handling employee grievances should be someone who:

• has been authorised and empowered to do so by the employer;
• is not in a position of actual or potential conflict; and
• is independent and impartial.

The grievance handler should be familiar with the organisation’s investigative procedure, have attended the relevant training to ensure full compliance with the same; and have a good understanding of the expectations and norms set out by the Tripartite Guidelines on Fair Employment Practices.

The employee does not have a legal right to stop the investigation. The employer must fulfil its obligation to investigate the alleged misconduct.

The employee under investigation is entitled to apply to the Court to stop the investigation. However, the employee bears the legal burden of showing that the employer has, for instance:

1. failed to comply with the organisation’s grievance policy;
2. committed a serious breach of natural justice; and/or
3. breached the implied term of mutual trust and confidence when investigating the matter, and that such a breach will, unless remedied, cause such prejudice to the employee that it would be more just for the investigation to be stopped than to be allowed to continue.

There is no legislation on a witness's role in investigations. However, the legislation on occupational safety requires that employees must report any irregularities they observe. Depending on the situation, participating in the investigation may also be part of the person's work duties, role or position, in which case the employer may require the employee to contribute to clarifying the situation. However, there is no formal obligation to act as a witness, and there is no legislation regarding the protection of witnesses. If a witness wishes, they may have, for example, an employee representative as a support person during the hearing. 

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.

Generally, the basic principles set out by the GDPR and the Finnish Data Protection Act apply to data processing in connection with investigations, including evidence gathering: there must be a legal basis for processing, personal data may only be processed and stored when and for as long as necessary considering the purposes of processing, etc.

Additionally, if physical evidence concerns the electronic communications (such as emails and online chats) of an employee, gathering evidence is subject to certain restrictions based on Finnish ePrivacy and employee privacy laws. As a general rule, an employee’s electronic communications accounts, including those provided by the employer for work purposes, may not be accessed and electronic communications may not be searched or reviewed by the employer. In practice, the employer may access such electronic correspondence only in limited situations stipulated in the Act on Protection of Privacy in Working Life (759/2004), or by obtaining case-specific consent from the employee, which is typically not possible in internal investigations, particularly concerning the employee suspected of wrongdoing.

However, monitoring data flow strictly between the employee and the employer's information systems (eg, the employee saving data to USB sticks, using printers) is allowed under Finnish legislation, provided that employee emails, chats, etc, are not accessed and monitored. If documentation is unrelated to electronic communications, it also may be reviewed by the employer. Laptops, paper archives and other similar company documentation considered "physical evidence" may be investigated while gathering evidence on the condition that any private documentation, communications, pictures or other content of an employee are not accessed.

The employer may collect the personal data of an individual without the individual’s consent or from a source other than the individual, where it is necessary for any investigation according to section 17(1) read with paragraph 4 of Part 3 of the Third Schedule of the Personal Data Protection Act 2012 (PDPA). Under section 2(1) of the PDPA, “investigation” means an investigation relating to:

• a breach of an agreement;
• a contravention of any written law, or any rule of professional conduct or other requirement imposed by any regulatory authority in the exercise of its powers under any written law; or
• a circumstance or conduct that may result in a remedy or relief being available under any law.

Under the Banking Act 1970, a bank and its officers cannot disclose customer information to third parties, subject to certain exceptions. An employer carrying out a workplace investigation does not fall within any of the exceptions.

Only the police can search employees' possessions (assuming that the prerequisites outlined in the legislation are met).

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.

In respect of data protection, the processing of personal data in whistleblowing systems is considered by the Finnish Data Protection Ombudsman (DPO) as requiring a data protection impact assessment (DPIA).

Under the Prevention of Corruption Act 1960 and the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992 (CDSCA), in any civil or criminal proceeding, no witness is obliged to disclose the name or address of any informer, or disclose any information that might lead to his or her discovery concerning offences such as corruption, drug trafficking, and money laundering, save where:

• in any proceeding for the offence, the Court, after a full inquiry into the case, is of the opinion that the informer wilfully made, in his complaint, a material statement that he knew or believed to be false or did not believe to be true; or
• in any other proceeding, the court is of the opinion that justice cannot be fully done between the parties without the discovery of the informer.

In line with the above, employers should therefore keep the informer’s identity confidential upon receiving a complaint relating to corruption, drug trafficking, money laundering, and other serious offences prescribed in the second schedule of the CDSCA.

Concerning a workplace investigation, there is no specific legislation in force at the moment regarding confidentiality obligations. All normal legal confidentiality obligations (eg, obligations outlined in the Trade Secrets Act (595/2018)), and if using an external investigator, the confidentiality obligations outlined in the agreement between the employer and the external investigator, apply. Attorneys-at-law always have strict confidentiality obligations as per the Advocates Act (496/1958).

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.

The process must be transparent and impartial, and therefore all the information that may influence the conclusions made during the investigation should be shared with the employee.

There is no specific list of information about the allegations against the employee under investigation that must be provided to the employee under investigation. However, the information provided to the employee must be sufficiently clear and specific so that the employee understands the case being made against him or her and can respond to it. The employee should also be made aware of the evidence against him or her and be given a reasonable opportunity to respond.

See question 11, there is no protection of anonymity as the process must be transparent to the parties involved.

Such information can be kept confidential, subject to questions 10 and 11. However, disclosure may nevertheless be compelled in court or arbitration proceedings as well as by disclosure requests or directions by the police or statutory authorities, including the MOM.

Yes, however, the need for an NDA is assessed always on a case-by-case basis.

Yes, NDAs can be used to keep the fact and substance of an investigation confidential. There are no express prohibitions against such NDAs under Singapore law. However, information or evidence covered by the NDA may still be discoverable in court or arbitration proceedings; and may also be subject to disclosure requests or directions by the police or statutory authorities, including the MOM.   

The privilege of investigation materials concerns a rather limited amount of cases. In practice, materials may be considered privileged in connection with the litigation process under the Procedural Code (4/1734). For example, communications between a client and an attorney may attract protection against forcible public disclosure.

Litigation privilege may attach to investigation materials if there was a reasonable prospect of litigation at the time of the creation of the materials, and the materials were created for the dominant purpose of a pending or contemplated litigation.

Legal advice privilege may attach to investigation materials if the materials were created to seek or obtain legal advice; or if the materials contain legal advice that is so embedded or has become such an integral part of the materials that the legal advice cannot be redacted from them. If the legal advice is separable from the materials, then only the parts of the materials containing legal advice will be protected by privilege.

The employee under investigation has a right to have a support person present (eg, a lawyer or an employee representative) during the hearings and a right to assistance in preparing written statements.

This is dependent on the employee’s employment contract and the employer’s internal grievance policies and investigative processes. There is no free-standing legal entitlement for an employee to have legal representation. Employers may, at their discretion, consider allowing an employee to bring a colleague or to have legal representation if such a request is reasonable, such as to provide emotional support to the employee who may view the disciplinary hearing as an unnerving and stressful experience or so that the employee may be advised and informed of his or her legal rights in respect of the investigation commenced against him or her.

A works council or a trade union does not have a role in the investigation.

An employee who is a member of a works council or trade union has the right to seek assistance from the works council or trade union representative (whichever is applicable) and have the works council or trade union involved in resolving the grievances.

For unionised companies, the grievance procedure and the role of the union representative are usually set out in the collective agreement entered into between the company and the works council or trade union. In some organisations, the employee handbook or grievance policy will also state when the trade union representative will be involved in the investigation process.

They can request assistance, for example, from an occupational health and safety representative, a shop steward or the occupational healthcare provider.

Employers may provide support, such as:

1. offering counselling for its employees to encourage open discussions and communication on any issues that they may be facing or clarify any questions they may have in respect of the investigation process;
2. reminding its employees of its zero-retaliation policy; and, if need be
3. making the necessary work arrangement to minimise potential interaction that would further aggravate the conflict or situation between the employees involved. 

Employers may also inform employees of the external resources available to them if they require any assistance in respect of the investigation provided by external parties such as TAFEP, the Singapore National Employers Federation, National Trade Union Congress, and Legal Aid Bureau.

If they are related to the work or workplace, the employer will handle the emerging matters separately. In internal investigations, the employer is allowed to use any material legally available.

If unrelated matters that require further investigation are revealed as a result of the investigation, the employer should take the necessary steps to investigate these matters, where relevant, under the employer’s grievance reporting, investigation and disciplinary processes. This should be done separately and independently from the existing investigation. Please note that section 424 of the Criminal Procedure Code imposes a legal duty on any person who is aware that another has committed certain specified offences to "immediately" report the matter to the police, "in the absence of reasonable excuse" not to do so. Failure to comply with this requirement is punishable with imprisonment for up to six months, and/or a fine.

If the nature of the grievance relates to the employer's obligations to handle such matters in general, the grievance will be investigated either separately or as a part of the ongoing investigation.

The employer should require the employee to raise the grievance under the company’s existing grievance reporting, disciplinary and investigation processes so that the grievance, to the extent that it is relevant to the current investigation, can be investigated together. Otherwise, the grievance can be dealt with separately and independently of the existing investigation.

As a general rule, sick leave does not prevent an investigation from progressing. Depending on the nature of the sickness, the employee can attend hearings and take part in the procedure. If the sickness prevents the employee from participating, the employer can put the process on hold temporarily.

If the employee under investigation has already responded to the allegations made against him or her and his or her participation is no longer required at this stage in the investigation, the employer may proceed with the investigation even while the employee is off sick.   

However, if the employee under investigation has not responded to the allegations made against him or her and his or her participation is still required in the investigation, the company may exercise its discretion to pause the investigation until the employee can assist in the investigations.  To prevent an employee from using a medical condition as an excuse to delay or avoid the investigation, the company may require the employee to provide specific medical documentation to address the issue of the employee’s ability to participate in the investigation and to adjust the investigation process accordingly. For instance, instead of scheduling an in-person interview, the company may send a list of written questions for the employee to answer, and may also extend timelines for responding, etc.   

If the employee is unable to return to work for the foreseeable future, the employer may consider reaching a provisional outcome based on the available evidence, which would be subject to change when the employee under investigation can return to work.

Regardless of a possible criminal investigation, the employer must run its internal workplace investigation without unnecessary delay. A workplace investigation and a criminal investigation are two separate processes and can be ongoing simultaneously, so the criminal process does not require the workplace investigation to be stayed. Thus, parallel investigations are to be considered as two separate matters. The police may only obtain evidence or material from the company or employer if strict requirements for equipment searches are met after a request for investigation has been submitted to the police.

Generally, there are no issues with an internal investigation being conducted in parallel to a criminal or regulatory investigation. The employer should inform the authorities of the ongoing internal investigation and comply with lawful directions from the authorities, for example, to share evidence gathered during the investigation with the authorities.

The employer's conclusions from the investigation.

The employee under investigation should be told of the findings that have been made against the employee, the disciplinary action (if any) that will be taken against the employee and any avenue or timeline for the employee to appeal the outcome of the investigation.

The employee under investigation may only be informed of the conclusions.

It would suffice for a summary of the investigation’s findings to be shared with the complainant and the respondent employees.

The employer decides whether misconduct has taken place or not. Depending on the case, the employer may recommend a workplace conciliation in which the parties try to find a solution that can be accepted by both sides. The employer may choose to give an oral reprimand or a written warning. If the legal conditions are met, the employer may also terminate the employment agreement.

The employer should take any follow-up steps required and keep track of whether any appeal against the outcome of the investigation is lodged. If any appeal is lodged, the employer should handle this appeal following its internal procedure. To the extent necessary, any disciplinary measures against the respondent employee should be stayed pending the outcome of the appeal.

In general, investigation materials, including findings, that includes personal data should only be processed by the personnel of the organisation who are responsible for internal investigations. However, it may in some situations be required by applicable legislation that findings are disclosed to competent authorities for the performance of their duties, such as conducting investigations in connection with malpractice and violations of the law.

A summary of the investigation’s findings should be disclosed to the employee who lodged the grievance and the employee under investigation.

If there are parallel criminal or regulatory investigations, the investigation findings should also be disclosed to the authorities.

Interview records or transcripts should be kept private unless disclosure is required by a court order or at the direction of the authorities.

Please see question 7. The outcome of the investigation involving personal data may be retained only for as long as is necessary considering the purposes of the processing. In general, the retention of investigation-related data may be necessary while the investigation is still ongoing and even then the requirements of data minimization and accuracy should be considered. The data concerning the outcome of an investigation should be registered to the employee's record merely to the extent necessary in light of the employment relationship or potential disciplinary measures. In this respect, the applicable retention time depends on labour law-related rights and limitations, considering eg, the applicable periods for filing a suit.

This depends on the company’s internal disciplinary policy and the severity of the offence. For instance, a written warning issued against an employee for minor misconduct is usually kept in the respondent employee’s file for one year and if the employee does not commit any further breaches during this time, the written warning will be expunged. However, if there is a finding of serious misconduct, particularly if such a determination results in the dismissal of the employee, these records are generally kept in the employee’s file for the duration of time such records are statutorily required to be maintained.  

There are no regulations regarding the actual investigation process. Therefore, the employer cannot be accused of procedural errors as such. However, once the matter has been adequately investigated, the employer must decide whether or not misconduct has taken place. If the employer considers that misconduct has taken place, the employer must take adequate measures for remedying the situation. Failure to adequately conduct the investigation could result in criminal sanctions being imposed on the employer as an organisation or the employer’s representative, or damages.

The employer may be exposed to legal action for a failure to properly conduct the investigation, including having such portions of the investigation set aside or held to be void by the courts, and be made to pay damages to the affected employee; or face investigation and administrative penalties by regulatory authorities such as the MOM.

In addition, after the Workplace Fairness Legislation comes into force, breach of its requirements may also expose the employer or culpable persons to potential statutory penalties. The Tripartite Committee on Workplace Fairness recommended, among other things, for the Workplace Fairness Legislation to provide for a range of penalties including corrective orders, work pass curtailment and financial penalties against employers or culpable persons, depending on the severity of the breach. It is thus expected that employers or culpable persons may be exposed to potential statutory penalties if the requirements of the Workplace Fairness Legislation are not complied with.
