Workplace Investigations

No specific rules directly govern a workplace investigation in the event of employee misconduct. However, several rules, both legal and administrative, affect the conduct of such an investigation. In addition, codes of conduct, internal regulations or guidelines may also exist within companies.

A new law (No. 2022-401) came into effect on 1 September 2022 and constitutes one of the cornerstones for future regulation of workplace investigations. This law transposes into French law the European directive relating to whistleblower protection. It does not, however, constitute a revolution, as a previous French law dated 9 December 2016 (the so-called Sapin 2 Law) already provided the whistleblower with a specific status and protection. These laws are fundamental when considering an internal investigation as the rules protecting the whistleblower and requiring the establishment of an internal whistleblowing channel (eg, a dedicated email or hotline) affect the degree of flexibility available to companies in conducting the investigation.

A new decree has been adopted (No. 2022-1284), dated 3 October 2022, for application of these new provisions. This decree sets out several obligations relating to the internal whistleblowing reporting process. The reporting channel will necessarily contribute to shape the internal investigation triggered by situations which have been reported by that channel. Companies subject to this decree may define the reporting procedure using the supporting tool of their choice (company collective agreement, internal memorandum, etc.), as long as the employee representative bodies are duly consulted on the matter. The decree also specifies that an acknowledgement of receipt of the alert must be provided to the author of the alert in writing within seven days from the company receiving the alert. The author of the alert must also be informed in writing, within a reasonable period not exceeding three months from acknowledgement of receipt of the alert, of the measures envisaged or taken to assess the accuracy of the allegations and, where appropriate, to remedy the situation which had been reported, as well as the reasons for these measures and, finally, the closure of the case.

More generally, not only do all the “pure” labour law rules relating to the protection of the human rights of employees need to be complied with (right to privacy, data protection under the GDPR, etc), but also the disciplinary rules and regulations that protect employees from unfounded sanctions imposed by their employer. For example, an employer can only sanction an employee's misconduct if the disciplinary procedure begins within two months of when the misconduct was committed or when the employer becomes aware of it. In this respect, an internal investigation can be necessary for the employer to obtain full knowledge of the facts alleged to have been committed by the employee. It is nonetheless recommended that the internal investigation be completed within these two months to avoid the risk of the disciplinary action being time-barred.

Administrative rules produced by the French anti-corruption agency should also be taken into consideration (good practice, guidelines and recommendations relating to senior management’s commitment to implement anti-corruption measures, corruption risk mapping, corruption risk management measures and procedures), as well as the guidelines produced by the French Ministry of Employment relating to the prevention of sexual harassment and gender-based violence or the recommendations of the Human Rights Defender, which is a French special institution aimed at protecting fundamental rights.

When the investigation in question concerns moral or sexual harassment or violence in the workplace, the national interprofessional agreement of 26 March 2010 should be <referred to. This text stipulates that in the event of an investigation procedure, it should be based on, but not limited to, the following guiding principles:

• it is in everyone's interest to act with the discretion necessary to protect everyone's dignity and privacy;
• no information, unless it is anonymized, should be divulged to parties not involved in the case in question;
• complaints must be investigated and dealt with without delay;
• all parties involved must be listened to impartially and treated fairly;
• complaints must be supported by detailed information;
• deliberate false accusations must not be tolerated, and may result in disciplinary action;
• external assistance may be useful, notably from occupational health services.

Many are calling for the adoption of legislative rules governing such investigations, and their coordination with general whistleblower protection measures.

Finally, a company must take its own rules and regulations into account. Every company with at least 50 employees has the legal obligation to draw up internal rules and regulations, which notably set out the disciplinary sanctions applicable to employees, as well as a reminder of certain employees' rights.

There are no specific legislative requirements for workplace investigations in Vietnam. However, Labor Code No. 45/2019/QH14 dated 20 November 2019 (2019 Labor Code), which is currently the primary legislation governing employment relationships, requires employers that have more than ten employees to provide a mechanism and procedure for handling sexual harassment cases in the workplace. Other than that, an employer may incorporate policies and guidelines on how to deal with workplace investigations into its handbook.

When a report of wrongdoing is brought to the employer's attention, whether through a whistleblower or another channel, and an internal investigation is expected, it may be either mandatory or optional, depending on the facts of the alleged wrongdoing.

The investigation will be mandatory when the alleged wrongdoing relates to an ethical issue according to anti-corruption regulations, the employer’s duty of due diligence regarding, for example, human rights or environmental matters, or where the works council has issued an alert relating to a “serious and imminent danger” (or to “fundamental human rights”), but also whenever it relates to the employer's obligation to ensure employee safety (eg, moral or sexual harassment).

If the investigation is not mandatory, it is up to the employer to decide whether or not to carry out the investigation. Several key questions can help the employer determine whether or not it is appropriate to carry out an investigation, such as:

• What are the benefits of doing nothing? The company will have to draw up a list of the pros and cons of an investigation, bearing in mind that in some cases a poorly conducted investigation could make the situation worse;
• What is the priority (eg, obtaining or securing evidence, or correcting the irregularity)?
• What rules or codes of ethics must the company comply with?
• Should external legal counsel only advise the company or should they play a major role in the investigation process by becoming an investigator?

The circumstances in which an employer commences a workplace investigation may vary, either through a whistleblower, through an internal system, email or phone call; complaints from suppliers, contractors, or customers; or accounts from observations and hearsay. Sometimes, it comes from anonymous complaints. However, it is common for an employer to verify whether the report or complaint is substantiated, partially substantiated, or unsubstantiated, which is sufficient to initiate and commence a workplace investigation.

An employee may be suspended or relocated during a workplace investigation by:

• suspending the employee as a precautionary measure (eg, pending a confirmation of dismissal);
• temporarily assigning the employee to another site; or
• exempting the employee from having to work while continuing to pay them their salary.

The employee can be suspended as a precautionary measure, pending confirmation of dismissal, but this implies that disciplinary proceedings have already begun and that the investigation is therefore at a relatively advanced stage and that there is sufficient evidence to suggest the need for disciplinary action. It should be made clear to the employee that the suspension is a provisional measure (in the absence of specifying this, the suspension could be interpreted as a disciplinary layoff constituting a sanction and, in some jurisdictions, as depriving the employer of the possibility of dismissing the employee for the same facts).

Temporary reassignment can also be considered. However, this contractual change must not apply for long and the measure taken must be temporary. The employer must act promptly – the measure is only valid for as long as the investigation continues. Failing this, and because of the absence of concurrent disciplinary proceedings, there is considerable risk that the temporary reassignment may be reclassified by a judge as an illegal modification of the employment contract or as a disciplinary sanction preventing the employee from subsequently being dismissed.

Finally, paid exemption from work is also possible and consists of temporarily suspending, by mutual agreement, the obligation of the employer to provide work for the employee and the employee’s obligation to work, without affecting their remuneration. Such a measure must generally be taken with the consent of the employee, because it implies a suspension (and therefore a modification) of the employment contract. This measure may be useful in temporarily removing an employee with whom the employer maintains a good relationship. This may be an employee who is or feels they are a victim of harassment, especially when the employee is not on sick leave.

Article 128 of the 2019 Labor Code explicitly states that an employer has the right to temporarily suspend an employee who is being investigated for committing an alleged act of misconduct in breach of the labour rules, if the following conditions are met:

• the misconduct committed is complex in nature, and any further work carried out by the employee may jeopardise the ongoing investigation. The law does not clearly define “complex nature”; it may be open to various interpretations by the employer. In practice and from our experience, allegations of sexual harassment may be considered complex misconduct and, therefore, can be a ground for suspension;
• the employer has consulted with (and effectively obtained the approval of) the grassroots-level representative organisation of the employee. No formal process is stipulated under the law for such consultation with this organisation. From our experience, the consultation can be in the form of a meeting between the management of the employer and the executive committee of the organisation. However, the organisation should require the employee to acknowledge their consent in writing by signing the meeting minutes;
• the period of suspension cannot exceed 15 days or 90 days in “special circumstances”. The law does not define what falls under “special circumstances”. In our view, this will be subject to the interpretation and discretion of the employer after consulting with the grassroots-level representative organisation of the employee; and
• the employee must be paid 50% of his or her wage that would be due during the period of the temporary suspension in advance. When the temporary suspension ends, if no disciplinary measure is imposed on the employee, the employer must pay the full wage for the period of the suspension by paying the remaining 50%.

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

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

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

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

An internal investigation is not a police enquiry or a judicial instruction; there is no legal provision enabling an employee to stop the investigation. At the same time, there is no legal provision enabling the employer to force an employee to be interviewed. Interviewing an employee within the context of an internal investigation is also not a disciplinary matter. Therefore, the employee has no right to be assisted by another employee or an employee representative. The employee could, however, lawfully request the presence of their lawyer, especially if the company’s lawyer is part of the investigation team.

The employee can only bring legal action to stop the investigation if he or she claims that his or her rights have been clearly and blatantly violated during the investigation. However, the employee bears a heavy legal burden of proof to substantiate his or her claims. Based on our experience, most of the time, it is very difficult for the employee to prove this and successfully stop the investigation.

Co-workers can spontaneously act as witnesses and provide statements to superiors before, during or after the interviews. Co-workers can also be interviewed as witnesses at the investigator’s request, although they are not under any obligation to answer the questions and they cannot be compelled to do so. The investigators have an absolute obligation of discretion during the investigation and cannot reveal any details of the information gathered.

Certain employees may benefit from whistleblower status, which implies that they may be exempt from potential criminal and civil liability relating to their report or testimony and they are protected from any retaliatory measures from the employer. “Facilitators” who helped the whistleblower and the individuals connected with the whistleblower and risk retaliatory measures by testifying as a witness may also benefit from this status, as of 1 September 2022.

There are no provisions in Vietnamese law that impose any statutory or legal obligation on an employee to act as a witness in an investigation. Hence, an employer does not have the power to compel its employees to act as witnesses in an investigation. However, a request for an employee to provide evidence or give details of an event that he or she knows of may reasonably be deemed to be a lawful and reasonable directive from an employer. Consequently, an employee’s refusal to act as a witness may be tantamount to an act of insubordination, which may lead to disciplinary action by the employer. In any circumstances, if an employee refuses to attend an interview or is generally not cooperating with an investigation, the reasons for this will need to be considered carefully by the employer.

GDPR principles fully apply to data gathering, as well as case law protecting the right to respect one’s private life and the secret of correspondence.

Decree No. 13/2023/ND-CP on personal data protection is the main data protection regulation in Vietnam. It regulates the processing of personal data, including the collection or gathering of data. If the physical evidence contains personal data of an individual, the gathering of physical evidence must comply with this decree.

In internal investigations, the fundamental rights and freedoms of employees are at stake,  including the right to privacy, respect for the privacy of home life and correspondence, freedom of expression, and the obligation of loyalty in searching for evidence.

In principle, work emails and files can be reviewed, even without the employee's consent, prior knowledge or warning. This includes: work email accounts; files stored on a work computer or a USB key connected to a work computer; and SMS messages and files stored on a work mobile phone and documents stored in the workplace unless they are labelled as “personal”. On the other hand, it is not permissible for an employer (or an investigator) to review “personal” emails and files, such as documents or emails identified as “personal” by the employee, or personal email accounts (Gmail, Yahoo, etc), even if accessed from a work computer.

There are certain exceptions to the above principle. An employer is allowed to check “personal” emails or data in any of the following cases:

• if the employee is present during the review;
• if the employee is absent, but was duly notified and invited to be present;
• if there is a particularly serious “specific risk or event”;
• if the review is authorised by a judge (this means having to prove a legitimate reason justifying not informing the employee).

When documents or emails are not marked as “personal” but contain information of a personal nature, the employer may open and review the data but may not use such documents or emails to justify applying disciplinary measures to the employee or use such documents or emails as evidence in court if they indeed relate to the employee’s private life.

Special attention must be given to employee representatives who must be entirely free to carry out their duties.

As part of an investigation, an employer may search the objects or files that are part of the company’s property (eg, company or employers’ laptops or phones for business purposes and emails or messages stored on the company’s servers) without prior notice and without the need of the consent of the employee. However, the employer has no right to search an employee’s personal possessions without consent.

To further avoid arguments or conflicts as to the right of ownership of a particular object or property, employers may specify in their internal policies, labour contracts, and handover documents what is to be regarded as the company’s assets and subject to a search in a workplace investigation.

Evidence obtained in the context of an investigation must specify who provided it and the date it was provided. No retaliatory measures may be taken against the whistleblower for the act of whistleblowing.

In certain cases, the whistleblower report must be forwarded to the judicial authorities (eg, when there is an obligation to assist persons in imminent danger, for serious offences or a disclosure that a vulnerable person is in danger (ie, minors under 15 or a person who is unable to protect themselves)).

It is up to the employer to determine whether or not to open an investigation after a complaint from a whistleblower. It is very important that the identity of the whistleblower is protected and that the employer also should not reveal the identity of the witness or the source of information, as the sources and witnesses may fear retaliation and feel uncomfortable or hesitant in giving information or raising concerns again.

Interviewers, investigators, interviewees or any others involved in the investigation are often bound by a reinforced confidentiality obligation, particularly when the internal investigation is triggered by a whistleblower alert. In addition, every person that comes to know of the investigation, facts or people involved is bound by an obligation of discretion. Furthermore, investigators should specifically be trained for interviews and be reminded of their obligations relating to the investigation.

The investigators will need to determine the order of the tasks to be carried out in the investigation, as this will have a significant impact on confidentiality management. Should they start with the hearings or a review of documents? The answer may depend on the subject matter of the investigation. It is advisable to first review the documentation before organising interviews, particularly to avoid the destruction of certain documents by employees acting in bad faith or by those wishing to erase the traces of alleged wrongdoing. Sometimes, however, it is possible to start with the interviews, especially in the case of harassment, as there may be no documents to review. If the decision is taken to conduct the documentation review after the interviews, it could be useful to ask the employees involved to sign a document stating that they must preserve and retain documents, meaning that if they delete or destroy documents, they would be acting against the company and in breach of the law.

Workplace investigations should be conducted in a strictly confidential manner to preserve the integrity and professionalism of the investigation and to protect the identity of the employee under investigation. This means that all information gathered, received, and shared during the investigation (ie, the subject employee and any material witnesses) should only be disclosed on a need-to-know basis.

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.

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.

The identity of the complainant must be kept confidential and cannot be disclosed. There are two exceptions: if the complainant consents to the disclosure; or if the employer is asked for this information by the judicial authorities.

The identity of the complainant and witnesses must be kept confidential and cannot be disclosed to anyone, unless both the complainant and witnesses consent to its disclosure or if the employer is asked to disclose this information by the competent authorities under Vietnamese law.

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.

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.

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.

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.

The employee under investigation has the right to be assisted by a lawyer during the interviews and, if the employee chooses to be so, the lawyer must also always be present. The employee may not, however, be accompanied by anyone other than a legal representative (ie, another employee cannot attend the interview).

Yes, the employee under investigation has a right to be accompanied or have legal representation during the investigation. Before the start of investigation proceedings, the employee under investigation must be informed about his or her right to have someone present with him or have a legal representative during the investigation.

Neither the works council nor the trade unions have any right to be informed or involved in the investigation. It is the employer who is responsible for carrying out the investigation. However, when the investigation is triggered due to a works council issuing an alert relating in particular to a “serious and imminent danger”, one member of the works council must be involved in the investigation process.

In Vietnam, the “trade union” is the only organisation solely dedicated to protecting employees’ legitimate rights and interests. Under the 2012 Labor Code, the term referring to trade unions was changed to “grassroots-level representative organisation of employees”. But the essence of this organisation remained and was later defined as “the executive committee of a grassroots trade union or the executive committee of the immediate upper-level trade union in a non-unionised company”. As such, it could be said that it was old wine in a new bottle.

As required under article 70.1 of Decree No. 145/2020/ND-CP, which serves as a guide to the Labor Code on working conditions and labour relations, when suspecting that an employee has committed a violation of labour discipline, the employer has to make a record of the violation at the time and notify the grassroots-level representative organisation of employees of which the employee is a member, or the legal representative of the employee if they are under 15 years of age. If the employer detects a violation after it has occurred, it will collect evidence to prove it. In this instance, the employer has no obligation to inform or involve the trade union or grassroots-level representative organisation of employees during the workplace investigation stage.

Also, an employee who is a member of the trade union or organisation has the right to seek assistance from this organisation and may authorise the trade union’s representative to represent and get involved in the workplace investigation.

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.

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).

Unrelated matters revealed during the investigation do not necessarily mean that another investigation will be opened. Nevertheless, if reprehensible acts unrelated to the current investigation are revealed, the employer will need to take action and sanction the perpetrator (after checking the facts). Sometimes the only way to check the facts is to carry out another investigation on a separate matter. However, the investigation team may also consider if there is enough connection between the matters to widen the scope of the current internal investigation.

If unrelated matters are revealed during the investigation, the employer should consider whether an investigation is needed. If necessary, the employer should decide whether it is appropriate to incorporate the new matters into the scope of the existing investigation by expanding the terms of reference. However, such action may not be appropriate if different individuals are involved or the inclusion of a new unrelated matter would unduly complicate or delay the progress of the existing investigation. If that is the case, the employer should investigate that matter separately.

Also, as detailed in article 19 of the 2015 Criminal Code of Vietnam, there is a legal duty on any person who is aware that a certain violation is being committed or has been committed to report it to the police unless otherwise provided for under law. Failure to comply with this requirement may lead to criminal liability for the offender.

The grievance may also have to be investigated (eg, moral/sexual harassment reported by an employee under investigation).

The employer should require the employee to raise any grievance under the company’s existing policy on grievance reporting, disciplinary, and investigation processes, so that it can determine if the grievance is relevant to the current investigation. The grievance can be investigated together with the ongoing investigation. It can also be dealt with separately and independently from the existing investigation.

The investigation will likely be able to continue with the other employees and, as soon as the employee under investigation returns from sick leave, they will be able to be interviewed.

However, as disciplinary sanctions are time-barred after two months from the moment the misconduct was committed or from when the employer becomes aware of it, if the sick leave lasts for the whole of that period, the investigation must be conducted anyway. In this instance, the investigator can ask the employee to attend the interview despite being on sick leave or arrange for the interview to take place using other means (eg, conference call). As a last resort, a questionnaire can be sent to the employee, but the pros and cons must be assessed as this is a way of information gathering that carries a certain amount of risk, could be less reliable and is of less probative value.

Workplace investigations do not require the presence or active cooperation of the employee under investigation. Thus, the investigation may start or continue in the employee’s absence due to illness.

If the employee’s presence is necessary for the conclusion of the investigation, the employer may invite the employee to provide information either by submitting his or her answers to a written questionnaire or attending a virtual meeting. However, the employee may not accede to the employer’s requests and proposals, especially if the employee has an illness. As a result, the employer may not be able to conclude the investigation due to the absence of the involved employee.

A criminal investigation always takes precedence over other investigations. However, this does not mean that the internal investigation has to stop. It can and should continue, and the report drawn up upon completion of the investigation could be used by the authorities in the criminal investigation. In some cases, especially when privilege does not apply, police or regulatory authorities may request that the employer share such evidence. However, even when privilege does apply, there is no certainty that the evidence would not have to be communicated to certain authorities.

Some administrative authorities often challenge the application of legal privilege or try to reduce its scope. For example, the French financial markets authority (AMF) regularly puts forward its view of legal privilege, according to which an email where a lawyer is only copied (and is not one of the main recipients) in from one of their clients is not confidential and can therefore be disclosed in proceedings. However, if the AMF investigators impose disclosure of privileged documents, this should result in the annulment of the investigation procedure. By way of exception, legal privilege cannot be invoked against certain other authorities, such as the URSSAF (authority in charge of collecting social security contributions) or the DGCCRF (directorate-general for competition, consumer protection and anti-fraud investigations). Where legal privilege is enforceable, the judge must first determine whether the documents constitute correspondence relating to defence rights and, second, must cancel the seizure of documents that they find to be covered by legal privilege due to the principle of professional secrecy of relations between a lawyer and their client and the rights of defence.

There are no issues with an internal workplace investigation being conducted in parallel to any criminal or regulatory investigation. In such a case, the employer should handle the workplace investigation meticulously, pay attention to all the facts and evidence, inform the authorities of the ongoing internal workplace investigation, and ensure that it complies with all applicable legal requirements or directions made by the relevant authorities concurrently. Also, the employer should not take any steps that interfere with, hinder, or obstruct the parallel investigations.

The employee under investigation, like the other employees interviewed and the whistleblower, must be informed that the investigation has been completed. However, there is no obligation to provide them with the report and, for reasons of confidentiality, it is very often best not to do so.

It is recommended that the employer informs the employee under investigation of the outcome and provides information on a need-to-know basis. Consequently, the employer has the discretion to proceed with any labour disciplinary procedure or actions against the employee based on the outcome of the investigation.

There is no obligation to share the investigation report. The findings, or a summary of them without revealing any confidential information, may be disclosed, but it is the employer’s responsibility to keep the identity of every person interviewed confidential.

There is no obligation to share the investigation report or the findings unless the employer and employee agree to do so.

However, under Decree No. 13/2023/ND-CP on personal data protection, the contents of the investigation report or findings related to the employee are likely to constitute the personal data of the employee under investigation. In that case, the employee may have a right under the said Decree to obtain copies of such documents by making a statutory data access request after the workplace investigation is completed. Where the employer is required to provide such documents to the employee under Decree No. 13/2023/ND-CP but the requested documents also contain the personal data of any other third parties (such as the employee’s co-workers who participated in the interview during the investigation), the employer should first redact or erase such data before providing the requested documents, unless the relevant third parties have consented to the disclosure of their personal data.

The employer can decide to sanction the person who was under investigation or to close the case. The employer may also need to protect any victims, witnesses and whistleblowers. If, during the investigation, it is discovered that a supplier or other commercial partner is implicated, the relevant contract may be terminated. The employer can take legal action , file a complaint (if the company is a direct victim of a criminal offence) or report the offence to the public prosecutor’s office. The employer must archive the file or ensure its lawful preservation after a certain period.

After the completion of the investigation, the employer may:

• take the appropriate labour disciplinary action against the employee;
• proceed with legal action against the employee (eg, reporting the criminal violations of the employee to the proper authority or filing a civil lawsuit against the employee before the court); or
• adopting preventive or remedial measures on how to avoid these violations and to mitigate the damage to the company (eg, reviewing internal policies and conducting employee training).

The findings must be submitted to the employer or management, but there is no obligation to disclose them to anybody else. The only exception is if a judicial investigation has been opened. In this case, the entire report must be provided to the authorities if the judge requests this. Normally the investigators only take written notes and there is no audio or video recording, unless the employee consents. Whether or not to make a voluntary disclosure of wrongdoing is a tactical decision for companies. Disclosure may mitigate fines and penalties or even help the employer avoid liability entirely. However, the downsides of disclosure include increased costs, the possibility of a follow-on government investigation and exposure to penalties. Thus, most companies assess their options on a case-by-case basis to determine what steps would be in the best interests of the company.

Generally, the employer does not have to actively disclose the findings of a workplace investigation to any party.

Notwithstanding this, the employer should be aware of certain statutory disclosure requirements that may apply as a result of the matters revealed during the workplace investigation, if the said investigation reveals any knowledge or suspicion of an indictable offence that has been committed.

Interview records should be kept private unless disclosure is required by the authorities.

If the outcome of the internal investigation has led to the sanctioning of an employee, this sanction may no longer be invoked to support a new sanction after three years. Moreover, under the GDPR principles, the duration of retention must be proportional to the use of the data. Therefore, the data must be retained only for a period that is “strictly necessary and proportionate”. If the employer wants to keep information about the investigation in the longer term, it is possible to archive the employee’s record even though the employer will no longer be able to use it against the employee after three years.

Vietnamese law does not provide for a period during which the outcome of the investigation should remain on the employee’s records and files. However, this will depend on the employer’s record-retention policies, which must comply with applicable data protection laws.

Within the context of an investigation following a whistleblower alert, any violation of the confidentiality obligation is punishable by two years’ imprisonment and a €30,000 fine.

If the employer fails to comply with its obligation to protect its employees’ safety, the employer will be liable for damages resulting from any failings during the investigation (eg, if sexual harassment is reported and no action is taken by the employer)

The employer may be exposed to legal action for its failure to conduct the investigation properly, such as a lawsuit for labour disputes or sanctions for its failure to protect personal data as required under personal data protection regulations. For instance, if there were errors during the investigation which led to erroneous results for the investigation and consequently, the employee was dismissed, the employee may file a claim for illegal dismissal against the employer.
