Workplace Investigations

Once the decision to undertake a workplace investigation has been made, it is important to decide who is the most appropriate person to conduct the investigation. For the investigation process to run smoothly a single lead investigator should be selected, although they may work with a larger team. The lead investigator and investigation team can be internally or externally appointed.

In deciding whether to appoint an external investigator an employer should consider:

• the nature of the allegations;
• the seniority of the respondent;
• whether a fair investigation can be conducted internally without any actual or perceived bias;
• whether there is a dedicated HR department with someone who has the required capability, skills and experience to conduct the investigation; and
• whether the employer wants the investigation to be covered by legal professional privilege.

If the employer decides to investigate the matter internally without appointing a third party, then the investigator does not need to have any specific qualifications. However, it is prudent to confirm that the investigator has the time and skills to conduct the investigation and that they can be objective.   

There are no prescribed minimum standards for this procedure. The responsibility for conducting these investigations lies with the employers. Internal compliance or legal teams are often entrusted with this task, as they are familiar with internal protocols. In practice, these investigations are often overseen by an internal team, occasionally with the assistance of law firms or auditing firms. Those involved in the investigation must remain impartial. Potentially biased persons, such as those under investigation and their close associates, should be excluded from participation.

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.

There is no statutory rule, and therefore the investigator can be chosen by the company.

In sensitive matters, it is recommended that attorneys undertake the investigation due to legal privilege. Engaging external lawyers increases the confidence of witnesses and parties in the independence and lack of bias of the investigation process, especially when the allegations involve senior employees.

Additionally, attorneys are trained to collect information based on legal thresholds that apply to the allegations, allowing the decision-makers to understand the events as they would be posed before a labour judge or a prosecutor, and enabling them to clearly assess the legal risk involved in the situation.

In some laws and regulations for specific industries, enterprises or personnel, there are certain requirements for the qualifications of investigators. For example, according to the Interim Measures for Investigating and Dealing with Disciplinary Violations of Professional Personnel by Medical Institutions, the personnel conducting an investigation and evidence collection shall not be less than two. If the investigator is a close relative of the investigated person, or a tip-off person or a key witness of the issue to be investigated, the investigator shall withdraw from the investigation.

However, at present, there are no unified and detailed national rules and regulations on the qualification of the investigators and organizations. In practice, the selection of the personnel and organizations responsible for internal investigation is usually based on the relevant provisions in the internal rules and regulations of the employer. The personnel conducting internal investigation are usually internal functional departments of the employer and are independent to some extent, including the personnel department, legal department, compliance department or risk control department. For significant or complex issues or senior management investigations, in order to ensure professionalism, accuracy and compliance, external law firms, consultants and accounting firms are also frequently hired to conduct investigations.

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

In determining who is to conduct a workplace investigation, the main objective is to ensure that the team is independent or at least that it is perceived as being independent. The key people in the investigation team can be identified in a pre-established procedure. It is good practice to give decision-makers the possibility to set up, on a case-by-case basis, the team most appropriate to the situation.

It is up to the company to decide who should carry out the workplace investigation and individual investigative steps. If their staff is used, the question arises of which person or department (compliance, legal, internal audit, HR or management) should take the lead. The answer to this question may depend on various factors such as the number of employees affected by the workplace investigation and the nature of the alleged misconduct. In any event, due to various employment law and data protection issues, the HR department and the legal department should be involved.

Further, it may make sense to bring in external advisors to lead the investigation together with an internal investigation team of the company. The engagement of an external investigation team can also be advantageous concerning the two-week exclusion period for termination for cause. This period does not start to run as long as the external advisors are investigating, but only when the persons authorised to terminate employment receive the investigation report.

As far as the persons in charge of an internal investigation are concerned, L. 4990/2022 on the protection of persons who report breaches of Union law provides for certain conditions that should be met when exercising their duties (ie, being impartial and abstaining when there is a conflict of interest), which also apply as general principles in all disciplinary procedures. Whistleblowing legislation stipulates that persons appointed to receive and investigate a whistleblowing procedure should meet certain conditions, including no penal proceedings against them, no disciplinary proceedings or convictions for specific offences, and no workplace suspensions.

Official disciplinary procedures are conducted by the competent bodies as described in the respective internal labour regulations.

Although not specifically regulated, support from external advisors (eg, lawyers) is allowed.

There are no statutory or regulatory requirements regarding the choice of investigator in workplace investigations. However, it is good practice to have the investigation conducted by persons who have been trained to do so as investigations may involve intricate issues. It is also important that the investigators are perceived to be impartial and fair. For that reason, the investigators should be individuals who are not involved in the matter under investigation.

Complex cases or cases that involve a senior employee may require someone more senior within the company to lead and oversee the conduct of the investigation. This also applies where it is foreseeable that the investigation may lead to disciplinary action, summary dismissal of the employee or a report to an authority.

Engagement of external parties or professional advisors may be necessary if the conduct under investigation is serious or widespread and may lead to regulatory consequences, or if the employer does not have the requisite expertise to handle the investigation. Lawyers (whether in-house counsel or external lawyers) may be the best fit to conduct a workplace investigation to ensure that legal professional privilege attaches to documents and communications created during the investigation (please see question 14).

Complaints pertaining to sexual harassment can only be investigated by the IC constituted under the SH Act.

For other kinds of misconduct, employers usually constitute a fact-finding investigation team with members who are independent and unbiased. The fact-finding team can be appointed internally, or the employer could also engage an external agency, depending upon the gravity and sensitivity of the matter, the nature of the issues being investigated or a desire to try and maintain legal privilege regarding the findings of the investigation.

An investigator does not have to hold any minimum qualifications. More often than not it is an employee's manager or HR manager who is carrying out the investigation. Crucially, the person carrying out the investigation must not be involved in the complaint, as an argument of bias could be made before the investigation begins. The investigator should also be of suitable seniority to the respondent and have the necessary skills and experience to carry out an investigation. If a recommendation by the investigator is made to progress the matter to a disciplinary process, which may in turn be the subject of the appeal, there should be adequate, neutral personnel within the organisation to deal with each stage. Again if the investigator and the disciplinary decisionmaker are the same person, an argument of bias will be made that will usually lead to a breach of fair procedures and any decision being unsustainable. Frequently, employers outsource the investigation to an external third party as there may simply not be adequate personnel within the organisation to carry out the process. Employers should ensure that within their policies the right to appoint an internal or external investigator is reserved.

In general, from an employment law perspective, there is no specific legal rule governing the minimum qualifications of who should conduct a workplace investigation. Generally speaking, a workplace investigation is carried out by the internal audit function, when there is one (generally in large companies), or by the HR or legal departments.

Outside the workplace, the employer may carry out investigations on the employee – normally without the latter knowing – through a private investigator. This investigation should be carried out to verify that the employee does not engage in conduct contrary to the company’s interests (eg, unlawful competition, disclosure of confidential information, criminal breaches). In such cases, the private investigator must comply with specific rules, mainly found in Italian Royal Decree No. 773 of 1931, according to which the investigator must, among other things: hold a licence issued by the competent authority; and keep a register of the activities conducted daily.

In addition, if there is a suspicion that a crime has been committed, the company may appoint a criminal law lawyer to conduct their own defensive criminal law investigation, as provided by article 391bis and the Italian Criminal Procedure Code.

There are no specific qualifications or requirements for an investigator. In many cases, the investigation is handled by a department or employee as deemed appropriate by the company. In some cases, an outside attorney may be asked to handle the investigation. Also, when it is a serious matter for the company, a third-party committee may be formed and commissioned to conduct an investigation.

However, under the revision of the Whistleblower Protection Act, which came into effect in June 2022, entities employing 300 or more employees must designate a person (whistleblower response service employee) in charge of accepting internal whistleblowing reports, investigating internal whistleblowing reports, or taking corrective measures as a whistleblower response service provider. Entities with less than 300 employees must also make an effort to do the same.

The person designated as a whistleblower response service provider must not divulge the name, employee ID number, or other information that would enable whistleblower identification without a justifiable reason. Criminal penalties (fines of up to 300,000 yen) have been established for violations of this confidentiality obligation.

Workplace investigations, if they are to be of value, must be conducted by an expert, professional and independent party. To safeguard the independence of the investigation, it is crucial that neither the contractor nor any other third party can influence how the investigation is to be conducted or how the outcome should be reported. The investigation must be conducted according to the protocol drawn up at the start and the investigator must not be involved in the follow-up to the outcome.

There is an ongoing discussion of whether lawyers can conduct an objective and independent investigation, due to the bias inherent to their profession. On the other hand, investigation bureaus or committees are also not necessarily independent, as they are not regulated and not subject to disciplinary law.

Typically, the legal department, the chief compliance officer, the HR manager, the audit committee or any other committee as may be set up by the company may conduct a workplace investigation. However, in other instances, the company may engage the services of independent external personnel to assist with conducting an internal investigation.

The minimum qualification or criteria of the person conducting the investigation should be as contained in the relevant company policies. Criteria may include independence, objectivity and impartiality.

Under the Safe Spaces Act, an employer should create an independent internal mechanism or a committee on decorum and investigation to investigate and address complaints of gender-based sexual harassment, which should:

• adequately represent the management, the employees from the supervisory rank, the rank-and-file employees, and the union, if any;
• designate a woman as its head and no less than half of its members should be women;
• be composed of members who are impartial and not connected or related to the alleged perpetrator;
• investigate and decide on the complaints within 10 days or less upon receipt thereof;
• observe due process;
• protect the complainant from retaliation; and
• guarantee confidentiality to the greatest extent possible.

For other types of offences, it is the prerogative of management as to who will conduct the investigation and how it will be conducted, provided the proceedings remain impartial.

There are no legal requirements in this regard but it is good practice if the team of investigators or individuals who deal with the case consists of:

• a person who has specific knowledge in a given field (concerning the violation);
• a member of the HR team; and
• a lawyer (it is recommended to engage an independent, external lawyer who can maintain the objectivity of the investigation, especially in complex matters or where a conflict of interest arises or may arise).

It is crucial that the investigators are independent (and they must be allowed to act independently).

Also, certain personal features are useful (eg, the ability to objectively assess a situation, empathy, and managing skills).

According to article 356(1) of the Portuguese Labour Code, the employer can appoint an instructor, who shall be responsible for the probationary proceedings. Usually, workplace investigations are conducted by external advisors (eg, lawyers), appointed by the employer.

However, regarding disciplinary powers, there is a legal limitation in article 98 of the Portuguese Labour Code. As such, only the employer (or the immediate superior of the concerned employee, if the employer has delegated its powers, as per article 329(4) of the Portuguese Labour Code) has disciplinary powers.

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.

While there are no laws that set minimum qualifications for who should conduct a workplace investigation, companies often engage external legal counsel to ensure the investigation is conducted in an unbiased and professional manner. If the company itself undertakes the workplace investigation, the company should take precautions such as ensuring that the person conducting the investigation is not biased and not involved in the alleged wrongdoing. If the person conducting the investigation cannot converse in the native language of the employee under investigation, the company may consider arranging for an interpreter when conducting interviews, to minimise the risk of misunderstanding.

As set out in question 1, workplace investigations must be proportional and companies must use the least intrusive means to affect employees’ rights. This translates into the following principles on who conducts the investigation:

• the enquiry must involve a minimal number of employees;
• only those employees with competencies on the investigated matters should be involved (normally human resources or compliance); and
• employees conducting the investigation must be qualified and have the power and seniority to do so proficiently (although a formal qualification is not required).

If the workplace investigation falls under the Swedish Whistleblowing Act, the investigation has to be conducted by independent and autonomous persons or entities designated under the Swedish Whistleblowing Act as competent to investigate reports.

If the workplace investigation is not governed by the Swedish Whistleblowing Act, there are no minimum qualification requirements. When appointing an investigator, one should consider who would be most suitable in the given situation. For example, it may in some situations be more suitable to have an external investigator to ensure impartiality.

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

The employer should conduct a workplace investigation on its own; however, an outside firm experienced in interviewing witnesses and assessing the credibility of evidence may also be appointed to assist with the workplace investigation.

There is no minimum qualification or criteria provided under Thai laws. It is worth noting that anyone who has been accused of misconduct or potentially has a conflict of interest should be excluded from any role in the investigation. This is to avoid a challenge from the subject employee that the investigation was not conducted fairly.

There is no compulsory requirement or qualification arising from the law as to the selection of the investigation team. The number and the profile of the investigation team need to be decided according to the characteristics of the case, whereas the head of the investigation team needs to be a competent and experienced investigator. A conflict of interest review is required to be conducted for the whole investigation team to protect the interests of the company. As conflicts of interest can also arise during an investigation process, relying on the support of an outside legal team should be considered, particularly for internal investigations that are likely to expand.

The investigator would typically be a line manager or HR representative. Complex cases, particularly if criminality is suspected, or cases where a senior employee is accused of misconduct, may require the investigator to be someone more senior within the organisation, or someone from the in-house legal team. Employers should bear in mind the need for someone more senior than the investigator to act as a disciplinary decisionmaker, if disciplinary action is found to be warranted.

Check the organisation’s policies and procedures, which may stipulate who can act as an investigator.

The investigator should be someone without any personal involvement in the matters under investigation, or any conflict of interest, but with sufficient knowledge of the organisation and where possible with both training and experience in conducting investigations.

The business should consider how any prospective investigator may appear if they are called as a witness in court, or to give evidence before any governmental committee or regulatory panel. They should also consider whether the employee accused of wrongdoing should have any say in the choice of investigator; this would not typically occur, but having the employee’s buy-in can increase the chances of a successful outcome to the investigation.

It is becoming increasingly common for businesses to use an external consultant or lawyer to conduct workplace investigations. This may be beneficial where it is not operationally viable within the employer organisation to have a different person conducting the investigation and the disciplinary hearing, or if the investigation is particularly sensitive or complex, or relates to a very senior employee. If an external investigator is appointed, the employer remains responsible for that investigation.

While every internal investigation should be carried out promptly, thoroughly and in a well-documented manner, employers should appoint one individual or team of individuals to oversee all complaints regardless of how they are received. Doing so helps to ensure that all allegations are documented, reviewed and assigned for investigation as consistently as practicable.

Once a complaint is received and recorded, the company should undertake an initial triage process to determine:

• the risk of the alleged misconduct from a reputational, operational and legal perspective;
• who is best suited to conduct an investigation based on the nature of the alleged misconduct and the perceived risk level (potential candidates may include members of human resources, legal or compliance departments, or outside counsel); and
• a plan for investigating the factual allegations raised in the complaint.

The appropriate investigator should be able to investigate objectively without bias (ie, the investigator cannot have a stake in the outcome, a personal relationship with the involved parties and the outcome of the investigation should not directly affect the investigator’s position within the organisation); has skills that include prior investigative knowledge and a working knowledge of employment laws; has strong interpersonal skills to build a rapport with the parties involved and to be perceived as neutral and fair; is detail-oriented; has the right temperament to conduct interviews; can be trusted to maintain confidentiality; is respected within the organisation; and can act as a credible witness.

At this triage stage, an employer may also wish to use the information collected from the complaint to proactively identify potential patterns or systemic issues at an individual, divisional or corporate level and react accordingly. For example, if a company receives a complaint against a supervisor for harassing conduct and that same individual has already been the subject of previous complaints, the company should consider whether it may be appropriate to engage outside counsel to carry out a new investigation to bring objectivity and lend credibility to the review – even if the prior complaints were not ultimately substantiated following thorough internal investigations. Similarly, the engagement of outside counsel is often appropriate where a complaint involves alleged misconduct on the part of a company’s senior management or board members.

There are no statutory minimum qualifications or criteria for someone to conduct a workplace investigation. The employer can simply delegate the investigation task to anyone. However, it is good practice for qualified persons with proper training in workplace investigations to conduct the investigation as these involve intricate issues. It is also important that investigators are fair, unbiased, and impartial. In addition, they should not be related to any parties involved in the investigation.

In complex cases or cases involving a senior or high-ranking employee, the employer should appoint a person with a higher authority or rank in the company to lead and oversee the conduct of the investigation. This also applies in instances where it is foreseeable that the investigation may lead to disciplinary action, summary dismissal of the employee, or a report to an authority.

There are instances when engaging with external parties or professional advisors may be necessary. This is especially the case if the conduct under investigation is serious or widespread, which may lead to regulatory consequences if the employer does not have the expertise to handle the investigation.
