Workplace Investigations

Investigation materials are not privileged and an employer may be required to disclose them in subsequent legal proceedings. If an employer is concerned about privilege attaching to an investigation, they should engage a legal practitioner to facilitate the investigation.

Employers who are concerned about privilege attaching to investigation materials should also consider the method of a lawyer’s engagement. The lawyer should be expressly engaged to investigate, report and to assist the employer by providing legal advice. Additional benefits can be achieved if the legal practitioner engages an external investigator to investigate the complaint and prepare the investigation report. Privilege will attach to the investigation materials because they are prepared for the lawyer to allow the lawyer to provide legal advice to the employer.

It is important that employers do not expressly or inadvertently waive privilege. For example, by disclosing the investigation report or substantial contents of the investigation report. It is a balance between providing information to the respondent and complainant about the outcome of the investigation and disclosing too much information.

If a lawyer is involved in the investigation, communication between the lawyer and client is subject to legal professional privilege. These communications must not be disclosed. Any documents collected by an internal audit can be seized and used. However, a document created by a lawyer can only be seized. The same applies to other professional representatives of parties, such as notaries and auditors, as potential holders of professional secrecy.

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.

Privilege attaches to investigation materials when attorneys conduct interviews and take notes, and when they write reports and recommendations.

However, if other persons participate in an interview or write a report, and they are not attorneys, they can be required to testify about what they witnessed while participating in the interview or to discuss or disclose their investigation report.

For this reason, when starting an investigation, and depending on the matters to be investigated, it is important to determine whether it is convenient to allocate lawyers to certain roles to increase the company’s control of corporate confidentiality resulting from third-party involvement in the investigation.

Attorneys should also clearly state to participants of the investigation that they are attorneys representing the company and that their work papers fall under attorney-client privilege and will not be shared with them.

The employer has the property right over all its properties. When discovering employee's misconduct, the employer is entitled to conduct an investigation within a certain scope according to the relevant laws and regulations, as well as the management system of the employer. Generally speaking, the employer is not required to obtain consent of the employee when conducting an investigation of the space and objects owned by it. The employer has no right to directly conduct an investigation of the employee's private space, objects, bank accounts and stock trading accounts. The public security organ or other public authorities should be involved in the investigation. In principle, if the employee's private space or objects are mixed with the employer's private space or objects, the employer should obtain consent of the employee for an investigation. Meanwhile, the employer's investigation should be controlled within the reasonable and necessary limit, and the employer is not allowed to illegally use or disclose the investigation results, otherwise it may constitute infringement. In addition, we also recommend that the employer stipulate explicitly in the employment contract and the internal management system that the employer has the right to detain and inspect the articles or equipment distributed by the employer, so as to reduce the compliance risk of internal investigation.

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.

Privilege does not generally apply to internal investigation materials as the investigation does not constitute a relationship between a lawyer and their client, and even less so a judicial investigation. However, if a lawyer is appointed as an investigator, privilege may apply to materials exchanged between the lawyer and that client.

The legal situation regarding attorney-client privilege for investigation materials compiled by external advisors (in particular investigation reports) is unclear. In principle, there is no absolute protection against seizure by the public prosecutor in the relationship between client and lawyer. Such protection only exists in the relationship between the accused in a criminal proceeding and his criminal defence attorney.

In recent years, German courts have repeatedly issued different rulings on the question of whether investigation materials (at the company itself or a lawyer's office) may be seized. In 2018, the Federal Constitutional Court (BVerfG) ruled that the seizure of documents at the offices of an international law firm that is not based in Germany, and therefore can not invoke German constitutional rights, is lawful. However, the BVerfG did not comment on what would apply to seizures at law firms based in Germany.

For violations that could lead to the company itself being exposed to investigative proceedings at some point and possibly having to defend itself, there are, in our view, good arguments for investigation materials being subject to attorney-client privilege. Additionally, the lawyer's hand file, in which he usually keeps his notes on the case or minutes of conversations with his client, may also not be seized. In all other cases, under the current legal situation, there is a risk that the materials may be seized, even in the office of the company’s lawyer. From a practical point of view, it is nevertheless advisable to label investigative materials, especially interview protocols and investigation reports, with a notice that they are confidential documents subject to attorney-client privilege and to store them not at the company’s premises but in an attorney’s office.

Regarding L.4990/2022 for whistleblowers’ procedures, many categories of privilege may occur during an investigation, such as: attorney-client privilege; doctor-patient privilege; and court or other proceedings’ privilege deemed as classified. L.4990/2022 provides that its provisions do not affect any of these privileges and these privileges supersede[6].

Privilege may also be attached to investigation materials in investigations relating to workplace harassment and violence incidents; however, since L.4808/2021 does not offer a specific provision and criminal proceedings may also commence, the matter of privilege must be examined ad hoc.

Legal professional privilege may attach to investigation materials if they are generated for the sole or dominant purpose of giving or obtaining legal advice (legal advice privilege); or created with the sole or dominant purpose of either obtaining or giving advice about or obtaining evidence to be used in an actual or reasonably contemplated litigation (litigation privilege).[1] Legal advice privilege applies to confidential communications between lawyers and their clients, whereas litigation privilege may extend to communications between lawyers, clients and third parties. The employer may withhold disclosure of any materials that are subject to either legal advice or litigation privilege.

In the context of a workplace investigation, internal interview records are protected by legal advice privilege if the dominant purpose of creating those records is to seek legal advice on potential disciplinary action against the employee. Such interview records are protected by litigation privilege if they are created to obtain evidence in an actual or reasonably contemplated litigation.

It should be noted that the point in time at which the sole or dominant purpose is judged is when the document is created. In other words, a document is not covered by litigation privilege if it was not created for litigation purposes but was subsequently used to obtain legal advice for litigation.[2] On a practical point, if the employer would like to minimise disclosure of the investigation by claiming privilege over relevant materials, it may wish to limit the number of documents created and persons to which they are circulated to avoid potential waiver of privilege.

Professional advice given by an "advocate" to a client is protected as “privileged communication” and is not admissible as evidence in a court of law. Such privilege may not attach to advice or communications involving in-house lawyers as they are not licensed advocates (since they are expected to surrender their bar licences when they take on in-house roles). This is a grey area as there are conflicting judicial precedents on this. Hence, communications, documents or information gathered during an investigation conducted entirely internally may not be legally privileged and may be discoverable in a dispute. That said, companies generally mark sensitive communications with in-house attorneys as privileged and confidential in an attempt to protect the same.

For the above reasons, investigations conducted by external advocates have better chances of retaining legal privilege. However, the following will not be treated as privileged information:

• any correspondence about the commission of a crime or fraud by the client; and
• the observations of an attorney that would suggest that a crime or fraud will be committed by the client.

It would be difficult to assert privilege over materials that relate to the investigation itself.

Privilege may arise before the instigation of an investigation where an employer may seek legal advice from their legal advisors over the initial complaint and appropriate next steps. Subject to the relevant tests being met, Legal Advice Privilege arises in respect of a confidential communication that takes place between a professionally qualified lawyer and a client. Who the client is will be of significant importance as they must be capable of giving instructions to their lawyer, on behalf of the employer. Caution should be exercised by employers if advice to "the client" is disseminated further within the business to other members of management. If such a scenario arises, then there is a risk that privilege may be waived and such material could be disclosable under a data subject access request. Litigation privilege arises with respect to confidential communications that take place between a lawyer or a client and a third party for the dominant purpose of preparing for litigation, whether existing or reasonably contemplated.

It is also prudent to consider whether an external investigator should have access to their own independent legal advisor, and the funding arrangements for such advice would have to be considered by the employer.

In general, from an employment law perspective, workplace investigations made by corporate departments (eg, HR and legal counsel who do not operate in their function as lawyers) are not covered by privilege. Generally speaking, privilege covers correspondence and conversations between lawyers.

In defensive criminal law investigations, legal privilege applies.

There are no specific laws or rules for the provision of confidentiality privileges other than that provided by the Fair Trade Commission Rules, which allow companies that are the subject of investigations into cartels, bid rigging, etc, to treat communications with their lawyers as confidential. However, when a motion for an order to produce documents is filed in a court proceeding, if the requested documents are "documents exclusively for the use of the possessor of the documents", the obligation to produce the documents is not recognised. If the investigation materials fall under this category, it is possible to exclude them from the scope of the court order to produce documents.

If an attorney is engaged to provide legal advice or representation in respect of the (subject matter of the) investigation and as such also conducts (part of) the investigation, work products prepared by such an attorney will typically be subject to the legal privilege. Such work products may include, for example, interview minutes, investigation reports, investigation updates, attorney-client correspondence on the investigation, and legal advice rendered in connection with the (subject matter of the) investigation.

Privilege attaches to investigation materials when a legal practitioner facilitates the internal investigation. Documents prepared during a workplace investigation will not automatically attract legal professional privilege, unless the investigation is facilitated by a legal practitioner.

The employer’s internal policy can indicate that investigation materials must be kept confidential.

In general, findings made and documents established during an internal investigation, including the report thereof, are not covered by privilege per se. It can be claimed that they are covered by the employer’s commercial secrecy, but this secrecy is not very well protected from requests of law enforcement authorities. Hence, if prosecuting authorities find a report of an internal investigation or other documents established during an investigation relevant for criminal proceedings, they can ask for them. If they are not produced voluntarily, a search can be performed.

Legal privilege will, on the other hand, cover an internal investigation if it is entrusted to an independent lawyer. Specifically, client-attorney privilege will cover all documents that are established during the investigation by a lawyer.

Under Polish law there is no distinction between legal advice privilege and litigation privilege. Hence, legal privilege will cover the documentation of the internal investigation led by a lawyer regardless of whether the lawyer’s involvement is for the purpose of obtaining legal advice or because of ongoing or contemplated litigation.

If any sources of information used within an investigation include privileged data, they may be redacted to safeguard third parties' rights. However, where disclosure of that data is necessary for the employee to understand why he or she is being accused, it may be necessary to reveal those elements. Otherwise, the employee may argue that their rights were affected and, for that reason, the disciplinary procedure – and any possible sanction – should be deemed null and void.

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.

No law recognises the common law concept of “attorney-client privilege” in Korea. However, communication with an attorney is protected to some extent under certain laws, such as the Constitution, the Attorney Act, the Criminal Procedure Act, and the Civil Procedure Act. This protection is based on the attorney’s confidentiality obligation, which prohibits an attorney from divulging confidential matters acquired in the course of representing clients, unless otherwise prescribed by law. This confidentiality obligation generally allows an attorney to refuse to testify or comply with document production orders for information or materials the attorney obtained in the course of his or her duties that relate to the confidential information of clients.

In addition, there could be instances where materials from an investigation conducted in Korea may become subject to discovery outside of Korea. It is, therefore, important to ensure investigation materials are privileged under the relevant non-Korean laws in the jurisdictions where attorney-client privilege is recognised (eg, the US).

As explained above, investigation materials are not protected by privilege per se. To protect the confidentially of these materials, it is advisable to enter into NDAs with the employees involved in the investigation.

Attorney-client privilege will apply to all communication and investigative material between a client and its law firm. Attorney-client privilege is, however, not without limitations. Regarding investigations into alleged employee misconduct, a law firm may have to report suspected money laundering to the authorities and under certain circumstances disclose information to the financial police.

Written material covered by attorney-client privilege generally may not be seized.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

Client-attorney privilege between qualified attorneys and the client (ie, an employer) begins once information is made available to the attorney, regardless of the form it takes.

Attorney-client privilege is attached at the time the attorney is hired as a legal representative. Attorney-client privilege, which is regulated under the Law of Criminal Procedure No. 5271 and the Attorney’s Act No. 1136, covers not only the investigation process, but also the legal advice and counselling received before and after the investigation. The importance of this privilege is especially present in cases where judicial or administrative authorities are involved in the process. Documents and correspondence benefiting from attorney-client privilege can be protected and fall outside the scope of preventive measures such as search and seizures due to the right of defence.

There are two limited types of privilege which may be relevant to investigations:

• Legal Advice Privilege (LAP), which protects communications between lawyers and their clients provided they are confidential and made for the dominant purpose of obtaining or giving legal advice; and
• Litigation Privilege (LP), which can extend to communications between a lawyer and client or third parties, but only where the dominant purpose of the communication is to prepare for or conduct existing or contemplated litigation.

If the relevant tests for privilege are met and apply to materials generated in the course of the investigation, the employer retains greater control over their subsequent disclosure to third parties. The materials would, for example, be protected against disclosure in any subject access request under the DPA 2018.

That said, privilege can be difficult to maintain in investigations, particularly where litigation is not active or in contemplation. Interview notes and witness statements may not attract privilege, particularly if these were conducted with employees who do not fall within the narrow definition of “the client” for LAP purposes (which is limited to employees who are capable of seeking and receiving advice on behalf of the employer).

If privilege applies to investigation materials, the investigator should keep tight control on what documents are created and how they are circulated, to avoid inadvertent disclosure and potential waiver of privilege.

Bear in mind that even if privilege applies to certain investigation materials, there may be a need to create disclosable documentation at a later stage, particularly if there is a decision to instigate disciplinary action.

For legal privilege to apply, a primary purpose of the investigation should be to provide legal advice to the company, including concerning non-lawyers working at the counsel’s direction, and legal privilege likely will not apply to internal investigations performed as part of the ordinary course of business or where the investigation is required by a state or federal regulatory regime (eg, post-incident investigations of operations governed by OSHA’s Process Safety Management Standards). It is, therefore, important to contemporaneously document the scope and purpose of the investigation and not risk waiving privilege by sharing privileged materials with unnecessary third parties.

Whereas attorney-client privilege includes only communications between an attorney and the client, work-product privilege is broader and includes materials prepared or collected by persons other than the attorney with an eye towards impending litigation. Examples of potential work products produced by attorneys in the context of an investigation include investigative work plans, interview outlines, memoranda summarising witness interviews and investigative reports.

As a practical matter, employees should be aware that communications with other employees or colleagues regarding the investigation are not privileged regardless of whether the colleague is also involved in the investigation or represented by the same counsel. Even if an employee believes he or she is sharing attorney communications with other employees who need to know the attorney’s advice and who also have attorney-client privilege with the same counsel because he or she is involved or implicated in the investigation and also represented by company counsel, it is always prudent to refrain from sharing privileged information. If an attorney’s communication is shared beyond those who need to know, attorney-client privilege may be destroyed.

Generally, privilege does not apply to internal workplace investigation materials as the investigation does not constitute a relationship between a lawyer and his or her client, and even less so a judicial investigation. However, if a lawyer is appointed to represent a specific party in an investigation, for example, as an investigator, the privilege may apply to materials exchanged between the lawyer and that client.

Employers should be conscious that the investigation may have an impact on the complainant, respondent and witnesses. Employers will need to consider how to support their employees. The level of support provided will often depend on the size of the organisation and programmes already in place.

Many employers have an Employee Assistance Programme and employees should be reminded about this programme if further support or assistance is required. An employer’s HR team may also be able to assist if an employee has concerns about the progress of an investigation.

There is no additional support for the employees concerned. However, the employer may offer support measures to the employees to ensure better cooperation. The choice of support measures is at the employer's discretion. For example, the employer could offer to bear lawyer’s fees, if the employee is cooperative. Such decisions must always be made on a case-by-case basis.

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.

It is highly recommended that investigation interviews are conducted in the interviewed person’s native language, even if the individual speaks the language used for business within the company, to ensure that there is no miscommunication or loss of accuracy in the determination of the facts. Also, speaking their native tongue reduces the discomfort of participating in the interview and potential extra work due to post-interview correction or confirmation. Depending on the scope of the investigation, the company can have attorneys who speak both the individual’s language and the company’s business language conducting interviews.

The relevant laws and regulations in the PRC have not made explicit requirements regarding the supports received by the employee involved in the investigation. In practice, the employer will usually prepare an internal time schedule before carrying out the investigation. Although the detailed time schedule will not be disclosed to the employee, the employer will usually inform the employee of each investigation in advance. In order to improve the transparency of the investigation, we recommend that employer should make positive and proper responses to employee who enquires about the progress of the investigation, so as to avoid employee's suspicion.

In addition, the Personal Information Protection Law of the PRC stipulates the rights of individuals in the process of personal information processing. In the scenario of internal investigation of an employer, the investigated party may, in accordance with such provisions, ask the employer for the right to review and even copy the personal information collected. Where the employee finds that the personal information collected by internal investigation is inaccurate or incomplete, he/she is entitled to request for correction or supplementation.

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

Apart from being informed of any facts and data concerning them being collected during the investigation, employees involved in the investigation do not have any specific rights. Some companies choose to use external firms specializing in psychosocial risk management, not only to conduct internal investigations, but also to provide additional psychological support for their employees, as part of the employer's safety obligation.

Generally, when employees may also use their devices for private purposes, the employer should ensure it allows its employees to tag their private data as "private". This tagging may facilitate the differentiation between business data (relevant for the investigation) and (non-usable) private data in the event of e-mail and electronic data screening.

In addition, the employer may, in appropriate cases, assure the employee that, if there is complete and truthful disclosure of facts to be clarified, the employer will refrain from imposing sanctions under labour and civil law (eg, a warning, termination of employment and the assertion of any claims for damages). In practice, assistance in finding a lawyer and the payment of legal fees is sometimes offered. However, such amnesty programmes are commonly only useful if there is a large number of cases that are particularly complex, poorly documented and difficult to resolve without amnesty offers.

According to L.4990/2022, any form of retaliation against complainants is prohibited, including threats of retaliation[9]. The complainants have the right to cost-free legal advice about possible acts of retaliation as well as cost-free provision of psychological support (to be defined by Ministerial Decisions)[10]. In terms of other types of support, the complainants are not in principle liable for the acquisition of information or releasing the information they reported under specific conditions (eg, the acquisition or access does not independently constitute a criminal offence, if they had reasonable grounds for believing that a report was necessary to reveal the violation)[11].

L. 4808/2021 states that the dismissal or termination of the legal relationship of employment and any other discrimination that constitutes an act of revenge or retaliation is prohibited and invalid[12].

It could be stressful for employees to be involved in a workplace investigation, whether as the victim, the subject of an investigation or a witness. More transparency in the process would help reduce stress. This could be achieved by providing the relevant employees with the timeline for different stages of the investigation and regular updates.

The employer may also consider providing mental health support to the employees concerned, for example in the form of counselling services or medical consultations. Where appropriate, the employer may also consider making reasonable adjustments to the employee’s workload and work schedule to facilitate his participation in the investigation.

Every workplace investigation is unique and varies based on the facts and circumstances of each case. As a result, the nature or type of support to be given to an employee would also vary from case to case. The bare minimum should be an assurance that there will be no retaliation against them for participating in the investigation. Other measures may include:

• changing the reporting relationship if the accused is the reporting manager or boss of the complainant;
• conducting investigations and interviews virtually or through videoconferencing in cases where parties or witnesses may not be able to physically appear before the investigating authorities; and
• allowing witnesses to be cross-examined virtually or through a written questionnaire where there is a fear of intimidation or retaliation from the parties.

The employer should be mindful that any interim measures or support it extends does not prejudice any particular party.

Under the SH Act, employers are legally required to assist the complainant if he or she chooses to file a complaint about workplace sexual harassment with the police under the Indian Penal Code or any other law that is in force. Further, the complainant can also seek interim protective measures from the IC, such as a request for transfer for the accused or the complainant or to grant leave to the complainant for three months. 

If an employee assistance programme is in place, an employee irrespective of their role in the investigation should be directed to the programme and encouraged to avail of the services. Investigations can become protracted and employees should be kept informed as to progress and what is required of them regarding participation. Regular checks of the health and well-being of employees should also be made. Even if such a programme is not in place, occasionally and depending on the issues giving rise to the investigation, it may be appropriate for the employer to cover the cost of counselling to a certain extent.

According to the law, there is no other specific kind of support other than what is mentioned above.  

There is no legally established assistance programme.

The employer can offer employees to be accompanied by another person, or by legal counsel, especially if the outcomes of the investigation could have consequences for their employment.

An employee being investigated has a right to be heard before a decision being made by the employer. Further, the body responsible for investigating the employee must be independent, so as not to be considered biased.

Since the conduct of an investigation is different from the administrative disciplinary process, management is given wide latitude for the exercise of the same.

After the employer determines that there are sufficient grounds to support the conduct of a formal administrative process, employees that are the subject of an administrative hearing should be allowed to present evidence to support his or her statements. Further, the employee may also provide affidavits of his or her co-employees consistent with his or her testimony.

They may be supported by, for example, allowing an alternative work environment (eg, remote work to avoid direct contact with people involved in the case). Depending on circumstances of the case, this solution will be offered to the subject or the victim. However, it is important that such actions do not infringe the rights of other people (eg, the subject itself).

Employees may also be sent on leave (by a unilateral decision of the employer – if possible under currently binding law provisions) or the parties to an employment contract may mutually agree to use such leave. Moreover, if they employer thinks it is necessary, they may assign the employee to another job for a period not exceeding three months (only if it does not result in a reduction in the employee’s remuneration and corresponds to the employee’s qualifications).

Also, depending on the employer’s decision – psychological or even legal assistance can be provided by the employer to a whistleblower or a victim.

Employees are usually assisted by lawyers when they are subject to an investigation or disciplinary procedure.

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.

There could be some instances where an employee involved in an investigation may be entitled to support from the company. To give an example, there have been some cases where a whistleblower claimed they suffered workplace harassment or their employer took retaliatory action (eg, wrongful transfer) and they sought damages or other relief.

For the reasons outlined in question 15, companies sometimes choose to voluntarily provide support to employees involved in the investigation (to ensure that evidence was lawfully obtained during the interview and is valid).

For investigated employees, one available support mechanism is for the company to cover the legal fees of an external counsel during the investigation or to offer to involve employee representatives. Reassurance may be provided to witnesses by guaranteeing, in writing, that their involvement in the investigation will be kept confidential and will not result in a detriment.

The employer is responsible for the work environment and must ensure that employees are not at risk of mental (or physical) illness due to an investigation. If an employee, in connection with an investigation, requires support or if risk of ill health is otherwise anticipated, the employer is obliged to assess the situation and provide said employee with sufficient support (eg, counselling or work adjustments).

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[2]

The employees may then file a complaint with the labour inspection officer of the Labour Protection and Welfare Department to investigate the situation if they view that the conduct of the employer in the investigation violates the LPA. For example, if the employer issues a written order for suspending an employee for more than seven days. The labour inspection officer may issue an order requesting compliance, where failure to comply with such an order would result in a criminal penalty.

The employees involved in the investigation should be granted their personal needs (such as refreshments or access to the bathroom), as well as translation services or transportation, if needed. A breach of these rights or needs during the process may constitute a violation of the law and adversely affect the validity of the results to be obtained from the investigation.

The employer needs to consider the health and wellbeing of all staff involved in the investigation, since this can be a very stressful process. The employer and investigator can assist by ensuring that all parties are aware of what is expected of them. Timings are also important; having a clear and expeditious timetable and providing updates if the timetable slips will help. Regular catch-ups by managers can be used to monitor how employees are coping. They should be reminded about any resources to help support them, such as employee helplines or employee assistance programmes.

Where an employer has particular concerns about an employee’s health, a referral to occupational health can assist. The employer may also wish to consider whether employees should be given additional time off, or whether any other adjustments can be made to the investigation process. For particularly serious allegations, the employer may consider facilitating the provision of independent legal advice for the employee, or making a contribution towards legal fees.

The employer’s counsel should provide an Upjohn warning at the start of any interview, and delivery of the warning should be documented by a note-taker. An Upjohn warning is the notice an attorney (in-house or outside counsel) provides a company employee to inform the employee that the attorney represents only the company and not the employee individually.

It is quite stressful for an employee, whether as the victim, the subject of an investigation, or a witness, to be involved in a workplace investigation. Thus, transparency in the investigation process would alleviate the employees’ stress and anxiety. This could be achieved by providing involved and concerned employees with the timeline for different stages of the investigation and regular updates. Further, the employer can make necessary work arrangements to minimise potential interaction with other involved employees so that it would not further aggravate the conflict or situation, (eg, days off or temporary suspension of work).
