Workplace Investigations

To ensure procedural fairness, the allegations must be put to the respondent in writing in advance of the investigation interview. The allegations must be specific, but the respondent does not need to be provided with a copy of the original complaint. The respondent should also be informed that if the allegations are substantiated they may result in disciplinary action up to and including the termination of the employee’s employment.

The purpose of internal investigations would be jeopardised by fully informing a suspected employee beforehand, as it would allow him or her to hide or destroy possible evidence, plan his testimony or coordinate with other employees.

There is no legal requirement to inform the employee of the allegations or suspicions.

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.

There is no obligation to inform an employee under investigation that this is the case, and it should not happen automatically.

While some policies require that the investigated employee be informed about the allegations against them at the beginning of the investigation, from a local perspective it is recommended that the accused employee be notified about the existence of the allegations if, after a reasonable review, there are elements that suggest that the accusation may be material.

In this context, the employee should be informed about the accusation and be allowed to confirm, deny, provide further context or justify each reported or identified event; offer evidence; and indicate persons or sources of information that could corroborate his or her defence. Information about the accusation must be focused on facts rather than on how the company obtained the information.

If the accusation is found to be groundless after initial review, involving the accused employee at the beginning of the process may have triggered unjust and unnecessary stress and a disruption in the employment relationship that may not be satisfactorily repaired by a determination that the accusation was void. This may result in a legal liability for the company or HR issues that could otherwise have been avoided.

Although there are no explicit provisions of law or policy requiring employers to provide specific information of allegations to investigated employees, in practice, at the early stage of investigation, in order to avoid alerting the investigated employee and reduce the possibility that the investigated employee may destroy the relevant evidence, the employer usually will not disclose the information of allegations to the investigated employee at the beginning of investigation. At the later stage of an investigation, when the employer has already obtained main evidence, the employer usually will properly disclose to the investigated employee the allegations that are clearly known by the employer and have sufficient evidence, and listen to the counterparty's opinions or argument, for the purpose of obtaining more information or getting the employee's confession.

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.

According to the French data protection authority, the employee under investigation must be informed of the name of the person in charge of the investigation, the alleged facts that have led to the whistleblowing alert and their rights to access and rectify data collected about them. This information must be given as soon as the data collection starts, before the interviews, as per GDPR principles.

In principle, the employer does not have to inform the employees about the investigation. Furthermore, there is no obligation to inform the "suspect" about the specific content of the workplace investigation itself and the allegations against him.

However, if personal data relating to the employee is collected and reviewed, the employee must be informed under German data protection principles (see question 7).

If the employer considers issuing a notice of termination based on the suspicion of wrongdoing, the employee must be allowed to comment on the allegations against him before receiving the termination notice. This requires that the employee be properly informed about the allegations and evidence against him. However, until the time of such a hearing, which usually follows the workplace investigation, there is no obligation on the part of the employer to inform the employee concerned about ongoing investigations.

As a matter of general principle, employees under investigation must have access to the necessary information to be able to defend themselves, in the context of their fundamental right to a fair trial and hearing.

Moreover, from a data protection perspective, they may be entitled to access their personal data in the respective files.

The above rights must be balanced with confidentiality and the need to safeguard the completion of the investigation and to protect the complainant from retaliation.

According to L.4990/2022, all data and information as well as the identity of the complainant are confidential, and any disclosure is only permitted where required by the EU or national legislation or during court proceedings, and only if it is necessary for the protection of the defence rights of the employee under investigation. The section of L.4808/2021 for the elimination of workplace violence and harassment does not regulate this specifically but provides a general obligation for confidentiality.

An employer’s internal policies or the employment contract may provide that an employee under investigation should be given certain information concerning the allegations raised against him or her. Such policies or terms should be followed and failure to do so may result in a claim for breach of contract or constructive dismissal by the employee. Even where there are no express provisions, the employer still owes an implied obligation of trust and confidence towards the employee at common law, which requires the employer not to, without reasonable and proper cause, conduct itself in a manner calculated and likely to destroy or seriously damage the relationship of confidence and trust between itself and the employee.[1] In the context of an internal investigation, the implied duty would require the employer to conduct the investigation and reach its findings reasonably and rationally following the evidence available and in good faith. This would normally require that sufficient information about the allegations made against the employee be provided to him or her such that he or she has the opportunity to properly respond to the allegations before any disciplinary action is taken or any decision about his or her employment is made.

As mentioned earlier, workplace investigations are normally a precursor to the actual disciplinary process against an employee. If the individual is being suspended during the investigation, the employer is only expected to inform the individual that they are being suspended on account of an ongoing investigation along with the broad nature of allegations or concerns, and does not need to disclose specific details about the allegations until the appropriate time. Further details may be provided at the investigation stage itself when the employee may be interviewed, or at the subsequent disciplinary inquiry.

Where a disciplinary process is necessary and initiated (after the investigation), the employee will have to be given a charge sheet or notice setting out the allegations against the individual in detail and be provided with an opportunity to submit an explanation. 

In sexual harassment investigations, the SH Act mandatorily requires the IC to submit a copy of the complaint to the accused. Further, the accused should be informed of the requirement to file his or her reply to the complaint along with a list of supporting documents, evidence, names and addresses of witnesses, etc, and the timelines for submitting his response in defence.

Under the fair procedures outlined above, details of the allegations or complaints against the employee should be put to them to enable them to fully respond to the allegations raised. The employee should also be provided with any relevant policies pertaining to the allegations against them, along with all documentary evidence of the allegations and the specific terms of reference that define the scope of the investigation. The employee should also be informed of their right to be represented, see question 15.

From an employment law perspective, our legal system does not provide a specific duty for an employer to inform employees that a workplace investigation is in progress.

In addition, disclosing such information could put at risk the outcome of the workplace investigation (eg, destruction of evidence), and it would therefore be arguable that no information should be provided to employees.

On the other hand, if, upon completion of the investigation, the employer decides to bring disciplinary action against the employee, then the latter must be informed of the complaints with a letter stating the procedure (see questions 3 and 12).

There are no specific legal stipulations or requirements regarding information, etc, that must be provided to employees who are the subject of an investigation.

An implicated person is typically provided with a summary description of the scope of the investigation and, hence, the allegations against such an employee (if any). This is usually done in the interview invite sent to the relevant interviewee, which also provides an opportunity to prepare for an interview and (if relevant) seek legal advice.

An employee must be given the full details of the allegations against him or her to enable the employee to make adequate representations against the complaints made against him or her.

During the fact-finding stage of the investigation, the employees under investigation are not generally entitled to information concerning the conduct of the investigation. It is the prerogative of management to involve the employee under investigation during the fact-finding stage. When, however, the employer determines that an administrative disciplinary process must proceed, the employee’s right to due process attaches. As such, due process includes the right to be informed of the grounds relied upon by the employer and the opportunity to be heard. The first notice or notice to explain should specifically inform the employee of the charge against him or her.

There is no specific mandatory information that should be given to an employee who is the subject of an internal investigation. However, it is common practice that he or she must know what the allegations against them are, on what grounds these allegations are formulated and be given a right to discuss these allegations and the evidence or grounds for these allegations.

If, before taking disciplinary action, the employer decides to open a preliminary investigation phase, the employee does not have to be informed.

Only when the preliminary investigation leads to a formal accusation will the employee be entitled to know that enquiries were carried out and the source of the facts (eg, witnesses, documents).

However, if an employer does not need to open a formal preliminary investigation phase, it only has to serve the accusation notice to the employee.

As a rule, employees will only know that they are being investigated if they are suspended or when they are notified of the accusation.

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.

There is no requirement to notify an employee under investigation concerning the allegations against him or her when requesting cooperation with a workplace investigation (eg, requesting the employee’s consent to review electronic data, or requesting an interview).

However, the company may strategically consider explaining the general purpose of the investigation before requesting consent to review electronic data or when requesting an interview. This may help increase the likelihood of cooperation and also reduce the risk of the employee raising objections to the company’s findings from the investigation by saying he or she was not properly informed of the purpose of the investigation, or that the investigation was conducted in a coercive manner.

It is not necessary to inform an investigated employee about an enquiry or of the allegations made against him or her. The obligation to disclose would only arise when:

• interviewing the employee would be the least intrusive means to investigate the facts; or
• if disciplinary measures are implemented as a result of the investigation. Since employees are entitled to challenge all disciplinary measures against them, they could request a court of law to disclose all the findings of the investigation, to assess if these findings could be useful to challenge the disciplinary measure.

According to article 14 of the GDPR, no information must be provided. The exemption in article 14.5(b) applies to the extent the obligation to provide such information is likely to render impossible or seriously impair the objectives of the processing of the personal data of the employee under investigation (ie, to diligently investigate the suspected irregularity).

If the Swedish Whistleblowing Act applies, information about where the personal data processed originates from may not be provided under article 14 of the GDPR, as the personal data must remain confidential subject to obligations under the Swedish Whistleblowing Act.

In addition to the above, an investigation should, to the extent possible and suitable, be characterised by the principles in ECHR (particularly articles 6 and 8). The employee under investigation should, among other things, be presented with sufficient information to safeguard his or her interests and be allowed to respond to the allegations. The investigation must also be compliant with the work environment responsibilities that the employer has concerning the involved parties (see questions 17 and 20).

As a result of the employer's duty of care (article 328, Swiss Code of Obligations), employees under investigation have certain procedural rights. These include, in principle, the right of the accused to be heard. In this context, the accused has the right to be informed at the beginning of the questioning about the subject of the investigation and at least the main allegations and they must be allowed to share their view and provide exculpatory evidence.[1] The employer, on the other hand, is not obliged to provide the employee with existing evidence, documents, etc, before the start of the questioning.[2]

Covert investigations in which employees are involved in informal or even private conversations to induce them to provide statements are not compatible with the data-processing principles of good faith and the requirement of recognisability, according to article 4 of the Swiss Federal Act on Data Protection.[3]

Also, rights to information arise from the Swiss Federal Act on Data Protection. In principle, the right to information (article 8, Swiss Federal Act on Data Protection) is linked to a corresponding request for information by the concerned person and the existence of data collection within the meaning of article 3 (lit. g), Swiss Federal Act on Data Protection. Insofar as the documents from the internal investigation recognisably relate to a specific person, there is in principle a right to information concerning these documents. Subject to certain conditions, the right to information may be denied, restricted or postponed by law (article 9 paragraph 1, Swiss Federal Act on Data Protection). For example, such documents and reports may also affect the confidentiality and protection interests of third parties, such as other employees. Based on the employer's duty of care (article 328, Swiss Code of Obligations), the employer is required to protect them by taking appropriate measures (eg, by making appropriate redactions before handing out copies of the respective documents (article 9 paragraph 1 (lit. b), Swiss Federal Act on Data Protection)).[4] Furthermore, the employer may refuse, restrict or defer the provision of information where the company’s interests override the employee’s, and not disclose personal data to third parties (article 9 paragraph 4, Swiss Federal Act on Data Protection). The right to information is also not subject to the statute of limitations, and individuals may waive their right to information in advance (article 8 paragraph 6, Swiss Federal Act on Data Protection). If there are corresponding requests, the employer must generally grant access, or provide a substantiated decision on the restriction of the right of access, within 30 days (article 8 paragraph 5, Swiss Federal Act on Data Protection and article 1 paragraph 4, Ordinance to the Federal Act on Data Protection).

The subject employee(s) should be informed of the details of the allegations, such as the details of wrongdoing or violations, made against them. This creates a fair opportunity for them to clarify themselves and defend against such allegations properly. Also, if there is any evidence that needs clarification from the employee, it should be shown to the employee.

Informing the employee under investigation on the subject, purpose and possible consequences of the investigation need to be evaluated by the investigation team before the interview. As a general principle, the interviewer is expected to share the information he obtained on the case with the employee, and ask for confirmation or clarification on these matters. The employee under investigation may be subject to an interview to gain information or as a confrontation if there is concrete evidence. If the evidence in hand is not based on concrete and material grounds, it would be more appropriate not to lead the interview to a confession, but inform the employee of the possible allegations. However, if the available evidence is based on concrete and material grounds, the interviewer may confront the interviewee by sharing the information that was gathered during the investigation in an attempt to obtain a confession.

The employee must be able to effectively challenge the allegations against them. They should be given the terms of reference for the investigation, and any relevant documentary evidence, including copies of witness statements.

The investigator must disclose to the employee under investigation the purpose of the investigation and, where the investigator is in-house or outside counsel, he or she should disclose that the company is the client.

There is no legal requirement as to what particular information should be stated in the allegations; however, such information must be provided to the employee under investigation. The information provided by the employer to the employee must be sufficiently clear and specific so that the latter understands the case or alleged issues against him or her and can respond to it.

Non-disclosure agreements, also known as confidentiality agreements, can be used to maintain the confidentiality of the investigation. In this agreement, the employee will be directed to maintain confidentiality concerning the investigation and matters that are the subject of the investigation, and not speak to anyone outside the investigation team about the investigation without authorisation.

Confidentiality agreements are legal documents. Employees should be informed that a breach of the confidentiality agreement could result in disciplinary action being taken against them, up to and including termination of their employment.  

According to section 6(1) of the DSG, employees who have access to personal data in the course of their professional activities must maintain data confidentiality and continue to do so even after termination of their employment.

Non-disclosure agreements can generally be used to achieve this but are subject to certain restrictions. They may not be used to conceal criminal activity, violate the privacy rights of individuals, circumvent legal disclosure obligations, prevent the exercise of legal rights or contain clauses that violate existing laws, in particular data protection regulations.

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, NDAs may be executed to reinforce the confidentiality obligations outlined in the company's policies and reinforced in interviews.

Yes. In practice, before conducting a compliance investigation, we recommend that the employer and the investigator enter into a confidentiality agreement to require the investigator to keep confidential the facts and the substance of the investigation. This will not only better protect the personal information of the complainant, the witness and the investigated employee, but also help the investigation to proceed smoothly.

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

Most of the time, the legal protection afforded by the legally prescribed confidentiality obligation that applies to whistleblowing is sufficient. This is all the more so given every person involved is bound by an obligation of discretion. However, there is no legal obstacle to the creation of an NDA between the employer and the people involved.

NDAs setting out a strict and reinforced obligation of confidentiality and discretion during the investigation should be signed by any external parties involved (eg, translation agency, IT expert) or when the internal investigation is outside the scope of whistleblowing regulations.

In principle, it is possible to conclude non-disclosure agreements with external consultants of the investigation or with employees involved in the investigation. However, regarding external lawyers, a non-disclosure agreement is not necessary since lawyers are already subject to professional confidentiality. Concerning employees, it is rare in Germany to conclude confidentiality agreements in connection with a workplace investigation.

NDAs are an option, especially to outline in detail the obligations of the persons conducting the investigation, which is also provided for in law. On the other hand, NDAs will not prevent persons involved from providing information to the competent authorities in the context of criminal or other similar procedures, where they must do so by law. Moreover, they may not protect confidentiality if persons who report breaches of Union law decide to make an external or public report, according to the provisions of L. 4990/2022.

In general terms, NDAs can be used and indeed are commonly used to keep the fact and substance of a workplace investigation confidential. However, NDAs will not be effective in preventing the disclosure of information which is in the public interest or is important for safeguarding public welfare in matters of health and safety. Further, several laws in Hong Kong provide that disclosures as a result of compliance with a requirement made by the relevant authorities will not be treated as a breach of any restriction imposed by contract or otherwise by law.[1]

Yes. While it is common for employees to be bound by general confidentiality obligations at the beginning of employment, it is advisable to reiterate such confidentiality obligations through NDAs during an investigation.

There is no legislation regarding NDAs, but there is a Bill before the legislature proposing to “restrict the use of non-disclosure agreements as they relate to incidents of workplace sexual harassment and discrimination”. It is currently at the report stage. Whether it passes remains to be seen, but there has in recent times been strong criticism of the use of NDAs to cover up matters that ought to be fully investigated and dealt with in an organisation.

Settlement agreements, however they arise, may include confidentiality clauses which may, depending on the terms of the agreement, extend to the fact and substance of an investigation, but as in the UK an employee's right to make a protected disclosure or report a criminal offence cannot be waived by signing an NDA.

Yes, in principle, NDAs can be used to keep the fact and substance of an investigation confidential, even if it is not strictly necessary (and not often done in our experience).

It is possible to use NDAs in investigations.

Yes, NDAs can be used for this purpose. However, employers in the Netherlands often rely on general confidentiality obligations that the relevant employee already has to adhere to vis-à-vis their employer, for example in the employment agreement or collective labour agreement, if applicable. It is good practice to reiterate the confidential nature of any interview and its contents, and the existence of the investigation as such, to avoid any alleged confusion as to the confidential nature of investigative procedures later on.

NDAs are usually part of an employee’s contract and, as such, create a contractual obligation between the parties privy to it. However, where the subject matter of an investigation borders on matters of a criminal nature, it might be impossible for parties to the NDA to continually uphold the obligation under the NDA because the parties have an obligation to the state to disclose facts of a criminal nature.

The practice of stipulating matters to ensure adherence to confidentiality is not uncommon. As such, NDAs are executed as a means of added protection for both the company and the employees involved.

Yes, but it may not stop the disclosure of information at the request of relevant law enforcement authorities.

Please see question 12 above. NDAs are not admissible.

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.   

Some companies require an employee subject to investigation to sign an NDA or other similar documents (eg, a pledge of confidentiality) agreeing not to disclose information relating to the investigation to outside parties.

Yes. NDAs are the preferred instrument to ensure that employees conducting the investigation, as well as those who participate as witnesses or collaborators, will keep the enquiry and its existence confidential.

NDAs can be used for some investigations carried out in the private sector. However, under the Swedish Whistleblowing Act, a contract is void to the extent it retracts or restricts a person’s rights under the Swedish Whistleblowing Act. An NDA that restricts the right to report irregularities to authorities or the media would, therefore, typically be void.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

Non-disclosure agreements can be made between an employer and employees who are involved in an investigation. This may include investigators and witnesses, apart from the employee under investigation. This minimises the risk of information being leaked, which can affect all parties related to the workplace investigation. However, an NDA is not absolute means to prevent the disclosure of confidential information, as the court has the authority to compel disclosure.

It is crucial to keep the events and facts of a workplace investigation confidential for the integrity of the process. It may be necessary to consider appropriate confidentiality measures to protect the complainant, mitigate risks, and preserve evidence. Damage to the confidentiality of the case can prevent the investigation team from bringing the case to a correct and complete conclusion. Although the labour legislation imposes a general confidentiality obligation on employees, NDAs can still be used as supplementary documents that may emphasise the confidentiality obligations of employees in workplace investigations and provide additional contractual protections such as penalties if there is a breach.

Only to a limited extent. As a matter of law, NDAs cannot prevent a worker from making a protected disclosure, or reporting a crime to the police. As a matter of the regulatory obligations of solicitors, NDAs should not be used in other ways, including as a means of influencing the content of disclosures, or by using warranties, indemnities and clawback clauses in a way that is designed to, or has the effect of, improperly preventing or inhibiting permitted reporting or disclosures (see the SRA’s warning notice on the use of NDAs).

This is a fact-specific inquiry that depends on the specific circumstances and laws of the relevant state. In general, NDAs are frowned upon but can be used to an extent to keep certain facts and the substance of an investigation confidential. NDAs can never prevent employees from assisting in official agency investigations, however. NDAs also cannot lawfully prohibit employees from officially reporting illegal conduct by their employer.

Generally, NDAs can be used to keep the facts and substance of a workplace investigation confidential. There are no express prohibitions against such NDAs. However, there are cases set out under Decree No. 13/2023/ND-CP on personal data protection where personal data is allowed or required to be disclosed without the data subject’s consent, in instances that are necessary to serve the public interest or to protect the life and health of the data subject.

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.
