Workplace Investigations
Contributing Editors
Workplace investigations are growing in number, size and complexity. Employers are under greater scrutiny as of the importance of ESG rises. Regulated industries such as finance, healthcare and legal face additional hurdles, but public scrutiny of businesses and how they treat their people across the board has never been higher. Conducting a fair and thorough workplace investigation is therefore critical to the optimal operation, governance and legal exposure of every business.
IEL’s Guide to Workplace Investigations examines key issues that organisations need to consider as they initiate, conduct and conclude investigations in 29 major jurisdictions around the world.

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. 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.

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).

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, 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.

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.
