Workplace Investigations

There is no specific legislation regarding a workplace investigation. In general, an employer has the right to investigate incidents at the workplace based on their authority over employees. However, the investigative powers of the employer are among others limited by the general right to privacy, which is also enshrined in Collective Bargaining Agreement No. 81 of 26 April 2002 to protect the privacy of employees concerning the control of electronic online data. If there are official complaints by employees due to sexual harassment, bullying or violence at work,  well-being legislation provides a specific procedure. Also, upcoming whistleblower rules include some specifications for an investigation, but at the time of publication these are not yet final (we refer to is in more detail below). The information below is only valid for workplace investigations in the private sector. The public sector has a set of specific rules and principles, which are outside the scope of this chapter.

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.

First, the employer should appoint an investigator or investigative team that will be responsible for conducting the investigation. Next, the employer or the investigators might think about communicating with the involved employees. It depends on the situation if this is a good idea or not. In general, it can be recommended that the employer is transparent towards the involved employees and openly communicates about the (start of the) investigation process. This is definitively the case if it is already clear that the involved employees are under scrutiny because of their actions. In this case, the actual investigation can begin with a hearing of the involved employees. However, if there is a risk that employees will hide or destroy evidence or will collude to prevent the employer from finding the truth, the investigation can also start without any communication. In this case, it would be better to start collecting evidence before hearing from the employees involved.

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.

In principle, you cannot unilaterally suspend an employee during a workplace investigation, as there is a risk of constructive dismissal (ie, wrongful termination of the employment contract by the unilateral modification of one of its essential elements). Consequences could include the payment of an indemnity in lieu of notice based on seniority as foreseen by the Employment Contracts Act, plus possible damages (three to 17 weeks remuneration if an unreasonable dismissal, plus alternative or additional damages based on real prejudice suffered). The parties can nevertheless agree on a suspension of the employment contract. In this scenario, the remuneration will still have to be paid. Furthermore, a suspension could be a sanction that follows the outcome of the investigation, but even then it will only be possible for a limited time (and a suspension without pay is usually only allowed by the courts for a maximum of three days). However, if the complaint is about sexual harassment, bullying or violence at work, the prevention advisor (see question 4) can recommend that the employer take certain actions, which in grave circumstances could lead to employee suspension. The suspended employee should continue to receive his pay if this occurs.

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).

In general, there are no legal minimum qualifications, the employer can delegate the investigation task to anyone. Of course, it is strongly recommended to appoint someone who is not involved in the case and who can lead the investigation objectively with the necessary authority to take investigative measures.

However, in the specific case of an official complaint due to sexual harassment, violence or bullying at work, the investigation will be conducted by the prevention advisor for psychosocial aspects. Next, if the investigation is based on an internal whistleblowing report, there will have to be an independent reporting manager responsible for receiving the report, giving feedback to the whistleblower and ensuring a decent follow-up to the report. Logically, the reporting manager will lead the investigation in this case, but he can be assisted by other persons or a team who are bound by a duty of confidentiality.

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.

This is only possible if the employee claims that his or her rights (eg, the right to privacy) are violated by the investigation (but this will merely limit the investigation methods) or if he or she finds that the investigation constitutes an abuse of rights. In any case, it will be very hard for an employee to completely halt the investigation.

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.

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.

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.

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.

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.

The employer is, in principle, not entitled to search the employee’s private possessions, except with the explicit consent of the employee. Digital files on the computer or laptop of an employee can be searched under the rules of CBA No. 81 (see question 7) and other privacy rules.  

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.

If the investigation is based on a whistleblower report that falls under the scope of the upcoming rules, the investigators are bound by a strict duty of confidentiality, especially regarding the identity of the report. The rules also provide some procedural deadlines for feeding back to the reporter. Within seven days of receiving the report through an internal reporting channel, the reporting manager needs to send a receipt to the whistleblower. From that moment, the reporting manager has three months to investigate the report and give feedback and an adequate follow-up to the report. Next, the rules offer strong protection against any retaliatory measures the reporter may experience. Regardless, these rules are mostly intended to offer the necessary protection for whistleblowers and to ensure that companies take necessary investigative steps following a report, but they do not include much information about the actual procedure of the investigation besides certain deadlines, nor do they deal with other employees involved (or under investigation).

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.

A workplace investigation is often a sensitive matter that requires necessary confidentiality to find out the truth discreetly and objectively. Nevertheless, there is often pressure from employees, trade unions or even the media and general public to be transparent and communicate about the case. From a legal perspective, it is not recommended to communicate openly about an ongoing investigation, as this can jeopardise the investigation or the possibility of taking disciplinary measures.

Whistleblower investigations will be bound by a strict duty of confidentiality regarding anything that could reveal the identity of the reporter.

In complaints due to sexual harassment, violence or bullying at work, the prevention adviser is bound by professional secrecy. Consequently, he or she may not disclose to third parties any information about individuals that have come to his or her knowledge in the performance of his or her duties. However, he or she still has the freedom to inform the people concerned to carry out his or her tasks in the procedure.

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.

In general, the employee should be informed that there is an ongoing investigation (unless this could jeopardise the investigation, in which case disclosure could be postponed until this is no longer the situation). Next, before imposing measures or sanctions, the employee should be allowed to be heard or to give his or her version of the facts. Of course, the employee can only do this if he or she is aware of the facts being investigated. It is not necessary to give the employee a full insight into the investigation, only the necessary facts that allow him or her to offer a defence are sufficient.

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.

If the complainant made use of an internal whistleblowing procedure, confidentiality regarding the identity of a reporter is mandatory. Also, in other cases and for other involved persons (witnesses), it is recommended to keep their identity confidential to prevent the risk of intimidation or other negative consequences.

In complaints due to sexual harassment, violence or bullying at work, if the prevention adviser heard or took written statements from persons that were considered useful for the evaluation, these persons may remain anonymous.

The employee must, nevertheless, receive sufficient information to be able to offer a defence concerning the facts of which he or she is accused.

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.

In principle this is possible. However, these NDAs do have their limits and cannot prevent involved persons from, for example, bringing a legal claim or filing a report if they are legally entitled to do so. Under whistleblower rules, a reporter can even publish his or her complaint under certain circumstances.

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.   

If the investigation is conducted by a prevention advisor, the investigation and the prevention advisor are bound and protected by a professional duty of confidentiality.

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.

An employee can be assisted by a member of a trade union. They are also free to consult a lawyer.

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.

At the request of the involved employee, an employee can be assisted by a member of the trade union delegation, for example, during his or her hearing.

The works council should be informed of an investigation if there is a considerable impact on the company; this will only be the case if the investigation concerns a very serious, important or widespread issue. This information should be communicated as soon as possible and before measures are taken as a result of the investigation. This is only a right to information, not consultation. Moreover, members of the works council may be asked to respect their duty of confidentiality. However, as the enforcement of this duty of confidentiality is difficult, the timing of the information should be chosen wisely so it does not jeopardise the investigation.

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.

There are no other mandatory support measures. However, an employer is free to offer additional support, for example, by granting leave from work. If tensions at the workplace are high, it may be a good idea to ask the employee under investigation to take some leave. Some companies also provide certain legal, moral or even psychological support. If the complaint concerns sexual harassment, bullying or violence at work, the prevention adviser can also recommend that the employer take additional measures to support certain employees.

Furthermore, under the whistleblower rules, an external reporting authority can grant any support measure (eg, legal advice or financial, technical, psychological or media-related, social support).

For complaints due to sexual harassment, violence or bullying at work, and if the facts are serious, the prevention adviser should, during the examination of the request and before giving his or her opinion to the employer, propose protective measures to the employer. These measures are necessary to avoid serious damage to the complainant's health or a significant deterioration in the situation (for example, causing opposing parties to commit criminal offences). The final decision on taking these measures rests with the employer. This means that the employer does not necessarily have to take the measures proposed by the prevention adviser. They may take other measures that provide an equivalent level of protection for the employee.

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 the investigation is not protected by confidentiality towards the employer (e.g. the prevention advisor cannot disclose confidential information to the employer), it could result in further measures taken by the employer or lead to a new investigation.

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.

This will depend on where the employee raises a grievance and the content of the grievance. If it is against the employer, the investigation can take this into account and continue from there. If the grievance is raised against the authorities, it will depend on the steps taken by the authorities.

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.

If this occurs, there is a risk that any measure resulting from the investigation (eg, a dismissal) can be (wrongly) interpreted as discrimination based on the illness of the employee. However, if the employer can prove that the measure is not related to the illness but solely related to the investigation (which is also not related to the illness), there may be no discrimination. The sickness of the employee may prevent the continuation of the investigation because, for example, it becomes impossible to hear from the employee. In this instance, the investigation can be suspended, postponed or extendeded until the employee returns. If it is a long-term absence, this could lead to a disproportionate amount of time to complete the investigation. Therefore, the employer should take any necessary steps to invite the ill employee to a hearing anyway (eg, through digital means). If the employee unreasonably refuses (several) of these invitations, it could be argued that the employee is wilfully boycotting the investigation and therefore forfeits his or her opportunity to be heard.

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.

In legal proceedings, a criminal procedure takes precedence over civil procedures. However, disciplinary internal proceedings (like a workplace investigation) and an investigation by the authorities may run parallel to each other. If the public investigation leads to a court procedure that results in the acquittal of the employee under investigation, it could lead to legal problems if the employer has already imposed sanctions based on the same employee. Therefore, the employer could make the internal investigation dependent on the public investigation, and could take preventive measures while awaiting the outcome.

The public authorities normally have the legal competence to request information that can help them in their investigation. Therefore, they could rightfully ask the employer to share evidence or findings from the internal investigation.

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.

It is highly recommended to inform the employee under investigation of the outcome. If disciplinary measures are imposed upon him or her, the legal procedure must be followed and the sanction must be imposed or communicated the day after the employer or his delegate has established the wrongdoing of the employee.

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.

It is recommended to limit the communication to the findings and details of the report that are necessary for the employee to fully understand the outcome. This is especially true if the investigation is bound by a duty of confidentiality (eg, under the whistleblowing rules), as the employee should not be allowed access to the full report.

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.

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.

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.

If the investigated acts constitute a crime, the authorities or the police should be informed. In certain cases, not doing so could lead to the company being accused of concealing a crime or becoming jointly responsible for it. However, if the company is the only victim of the crime and it is minor, the company may choose not to inform the authorities. For example, there is an enormous difference between a bank employee stealing large amounts of money from clients and an employee who is stealing toilet paper from the company. As stated above, the interview records could be at risk of disclosure if the authorities or police seize them for their investigation.

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.

According to the GDPR, personal data should only be stored for a proportionate amount of time. Usually, this means that it can be stored as long as it is relevant for the employment contract, and even afterwards, if there is a risk of legal proceedings (ie, regarding the dismissal of the employee).

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.  

In general, abusive investigations could lead to a legal claim regarding the abuse of rights. During an investigation, an employer should be guided by principles of due diligence and not take disproportionate action. If the investigation causes unnecessary damage, involved employees could file for compensation (eg, before the labour court). Next, the employer is also responsible for following the mandatory procedure for official complaints regarding sexual harassment, bullying and violence at work and investigations of whistleblower reports. In the first case, an employer who does not follow the procedure or obstructs the procedure can be liable for penal or administrative fines (maximum 8,000 euro) or, if the employer has not taken necessary measures to mitigate the risks for the employee and the employee suffers damage to their health, they may be liable for a fine of a maximum of 48,000 euro and imprisonment for between six months and three years. In the second case (whistleblower procedure), if an employer did not follow or has obstructed the procedure, they can be fined up to 5% of the annual revenue of the preceding year.

If the complaints involve allegations of sexual harassment, violence or bullying at work, the employer might risk an investigation of the inspection on supervision and well-being at work. If the prevention advisor finds out, before giving his advice, that the employer did not take any suitable protective measures after they were recommended, the prevention advisor is obliged to call an inspection on supervision and well-being at work.

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.
