Workplace Investigations

In Greece, workplace investigations are not heavily regulated.

However, internal disciplinary procedures are governed by certain general principles, while there is also legislation regulating certain aspects of investigations opened in the context of whistleblowing procedures or concerning complaints for workplace violence or harassment. These include Law 4990/2022, which transposed EU Directive 2019/1937 into Greek Law; and Law 4808/2021, which ratified the ILO’s Violence and Harassment Convention, 2019 (No190) and introduced relevant provisions.

As far as disciplinary procedures in private-sector companies are concerned, employers that must have internal labour regulations in place (ie, those with more than 70 employees) or opt to adopt them voluntarily, can regulate the procedures themselves.  

In the public sector, internal investigations are governed by disciplinary provisions included in the civil servant code.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

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.

Internal investigations can be initiated either upon a complaint or report by an employee, (or other persons providing services or seeking employment, etc) in the workplace or by the employer as part of their managerial right.

If from an employee, the complaint or report may fall within the scope of an internal disciplinary procedure, if any, or may concern an alleged workplace violence or harassment incident, or fall within the scope of L.4990/2022 on the protection of persons who report breaches of Union law.  

Reports by whistleblowers are submitted to the manager with responsibility for receiving and monitoring reports, a person appointed for that purpose under L.4990/2022. Complaints for incidents and harassment in the workplace can also be submitted, according to L.4808/2022, to the person or internal body specifically assigned to receive such complaints. Both laws require the employer to define the persons competent for receiving and monitoring complaints or reports and notifying the employees stricto sensu and any other persons falling within the scope of the respective provisions.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

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.

Internal labour regulations may allow for the suspension of an employee when there is reasonable suspicion that a disciplinary offence has been committed. Given that under Greek law employees have the right to receive wages and to be employed, suspension without a specific provision in the internal labour regulation may only be imposed in an extreme case where the offence and the risk of keeping the employee employed during an investigation is obvious.

Payment of remuneration during suspension should not be withheld, otherwise, the suspension could be considered a disciplinary penalty not provided in law and imposed without completion of the disciplinary procedure, thus illegally harming the employee.

In any case, suspension is one of the ultimate measures that may be taken, in contrast to, for example, a change of work position.

It is possible to suspend an employee during a workplace investigation.[1] While there are no limits on duration, the employee will remain entitled to full pay during this time.

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%.

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

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

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

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

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.

Although there is no specific legal provision, access to legal action and judicial proceedings cannot be obstructed under any circumstances as this is a fundamental right under the Greek constitution. Thus, if an employee manages to bring legal action to stop the investigation (eg, a prolonged investigation for a frivolous complaint harms them), then the investigation may have to be temporarily paused or permanently terminated depending on the court decision.

The accused could theoretically request a court to stop the investigation, for instance, by arguing that there is no reason for the investigation and that the investigation infringes the employee's personality rights. However, if the employer can prove that there were grounds for reasonable suspicion and is conducting the investigation properly, it is unlikely that such a request would be successful.

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.

Indirectly involved employees may be interviewed as witnesses in the context of the investigation, as the employee has a duty of loyalty towards the employer originating from the employment relationship. However, they cannot be forced to do so (in contrast with criminal procedures). Any harmful act that could be considered retaliation against witnesses in the context of violence or harassment or whistleblowing investigation is prohibited. In addition, the identity of any employees as witnesses is also covered by the principle of confidentiality.  

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.

The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

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 and the provisions of L. 4624/2019 regulate the gathering of physical evidence from a data protection perspective, providing, among other things, that personal data should be processed with transparency and to the extent necessary for the investigation.

L.4990/2022 on the protection of persons who report breaches of Union law regulates data protection issues in the context of whistleblowing investigations, mainly to safeguard confidentiality throughout the investigations.  

The Swiss Federal Act on Data Protection applies to the gathering of evidence, in particular such collection must be lawful, transparent, reasonable and in good faith, and data security must be preserved.[1]

It can be derived from the duty to disclose and hand over benefits received and work produced (article 321b, Swiss Code of Obligations) as they belong to the employer.[2] The employer is, therefore, generally entitled to collect and process data connected with the end product of any work completely by an employee and associated with their business. However, it is prohibited by the Swiss Criminal Code to open a sealed document or consignment to gain knowledge of its contents without being authorised to do so (article 179 et seq, Swiss Criminal Code). Anyone who disseminates or makes use of information of which he or she has obtained knowledge by opening a sealed document or mailing not intended for him or her may become criminally liable (article 179 paragraph 1, Swiss Criminal Code).

It is advisable to state in internal regulations that the workplace might be searched as part of an internal investigation and in compliance with all applicable data protection rules if this is necessary as part of the investigation.

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.

As a first step, the employer should ask for the employee’s permission to access their possessions and files. Employment contracts and internal labour regulations may include provisions regarding an employer’s access to employees’ documents created and kept for business purposes or related to business activity.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

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.

L. 4990/2022 includes specific requirements regarding, among other things, the procedure of receiving and investigating respective reports, confidentiality issues (especially regarding the identity of the whistleblower), data protection issues (including restrictions to the right of access) and the employer’s right to keep a record of the relevant complaint and investigation. Such provisions are expected to be further detailed by Ministerial Decisions in future.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

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.

Confidentiality applies as a general principle in disciplinary investigations.

Moreover, L. 4990/2022, which transposed EU Directive 2019/1937 into Greek Law, regulates the issue of confidentiality during investigations that start based on an internal report. The managers conducting the investigation must respect and abide by the rules of confidentiality regarding the information they have become aware of when exercising their duties[1]. They must also protect the complainant’s and any third party’s (referred to in the report) confidentiality by preventing unauthorised persons from accessing the report[2].

Finally, L. 4808/2021 provides that employers must create a procedure that should be communicated to employees regarding all the necessary steps of an investigation following a complaint. Throughout the whole process, the employer, managers and the employer’s representatives responsible for the investigation must respect and abide by the rules of confidentiality in a manner that safeguards the dignity and personal data of the complainant and the person under investigation[3].

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

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.

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.

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).

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.

According to express provisions of L.4990/2020, in principle personal data and any other information that may lead directly or indirectly to the identification of the complainant must not be disclosed to anyone other than the investigating individuals unless the complainant gives consent[4] and that is why pseudonyms should be used. The witnesses and third persons that aid the complainant are deemed as “mediators” by the Law and their contribution to the procedure should be confidential[5].

L.4808/2021 does not indicate when such disclosures are permitted; however, it is obvious that this is a matter of cost-benefit analysis where the public interest and the fundamental rights of the involved persons should be considered in a balanced way to ensure the best results. From a data protection perspective, it could be argued that the person under investigation’s right to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of these persons.

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]

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.

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 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.

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.

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.

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.

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.

Greek law does not specifically regulate the right to be accompanied or have legal representation during internal investigations for private-sector employees.

However, the right to legal representation established in article 6 of the European Convention on Human Rights could be interpreted to cover cases such as internal investigations in the workplace. In addition, according to article 136 of Civil Servant Code, the employee under investigation has the right to be represented by an attorney at law. There is an additional argument regarding private-sector employees and their right to legal representation, by applying this provision by analogy.

In the case of an employee involved in an internal investigation, a distinction must be made as to whether the employee is acting purely as an informant or whether there are conflicting interests between the company and the employee involved. If the employee is acting purely as an informant, the employee has, in principle, no right to be accompanied by their own legal representative.[1]

However, if there are conflicting interests between the company and the employee involved, when the employee is accused of any misconduct, the employee must be able to be accompanied by their own legal representative. For example, if the employee's conduct might potentially constitute a criminal offence, the involvement of a legal representative must be permitted.[2] Failure to allow an accused person to be accompanied by a legal representative during an internal investigation, even though the facts in question are relevant to criminal law, raises the question of the admissibility of statements made in a subsequent criminal proceeding. The principles of the Swiss Criminal Procedure Code cannot be undermined by alternatively collecting evidence in civil proceedings and thus circumventing the stricter rules applicable in criminal proceedings.[3]

In general, it is advisable to allow the involvement of a legal representative to increase the willingness of the employee involved to cooperate.

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.

L.4990/2022 explicitly states that the exercise of employee rights that refer to consulting from representatives or trade unions and protection against any detrimental measure that results from those consultations does not affect the implementation of any legal provisions. The autonomy of social partners and their right to enter into collective agreements regardless of the level of protection provided by L.4990/2022[7] is also unaffected.

Under L.4808/2021, legal persons and associations of persons, including trade unions, that have a legitimate interest in doing so may, with the consent of the complainant, bring an action in the complainant’s name before the competent administrative or judicial authorities. They may also intervene in their defence[8].

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.

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.

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

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

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

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

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).

If any unrelated matters are revealed as a result of an investigation and are of legal importance, the applicable legal provisions must be implemented and any relevant policies or agreements between the involved parties should be taken into account. For example, if the reporting procedure sheds light on other criminal acts, criminal law procedure may be followed if the matter is reported to the competent authorities.

If these unrelated matters fall under the ambit of another company’s policies, the relevant procedures may also be followed separately. However, the employee under investigation must be allowed to defend him or herself, otherwise he or she may raise complaints relating to the procedural guarantees of the investigation.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.

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.

Employees under investigation frequently raise grievances during investigation procedures that are dealt with on a case-by-case basis. The grievances raised by the employee under investigation are examined by the employees responsible for the investigation. They may either pause the relevant proceedings and review the grievance, especially if the claims of the employee under investigation are linked to a breach of his or her data or hearing rights, or they may continue the investigation.

In the context of private internal investigations, grievances initially raised by the employee do not usually have an impact on the investigation.

However, if the employer terminates the employment contract due to a justified legal complaint raised by an employee, a court might consider the termination to be abusive and award the employee compensation in an amount to be determined by the court but not exceeding six months’ pay for the employee (article 336 paragraph 1 (lit. b) and article 337c paragraph 3, Swiss Code of Obligations). Furthermore, a termination by the employer may be challenged if it takes place without good cause following a complaint of discrimination by the employee to a superior or the initiation of proceedings before a conciliation board or a court by the employee (article 10, Federal Act on Gender Equality).

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.

In principle, the health of an ordinary employee would not prevent the investigation procedure from taking place (eg, interviews with witnesses or the collection of evidence would not be postponed or suspended). However, if the employee under investigation is unwell and they can't participate in the procedure, the investigation may be suspended or postponed until the employee can take part. Bearing in mind the majority of company internal policies and regulations governing workplace investigations provide for a specific framework and timetable for the whole procedure to be completed, the long-term sickness of an employee under investigation may impede the completion of the procedure in the prescribed time. As a result, the person conducting the investigation may seek alternative measures to facilitate participation (eg, teleconferencing).

On a related note, if sickness occurs after the investigation is completed and the employer decides upon the imposition of disciplinary measures against the said employee and the initiation of a relevant procedure, the decision should be duly and timely communicated to the employee, irrespective of whether his or her presence in the workplace is not possible because of the illness.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).

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.

Incidents of violence and harassment may be dealt with by certain independent authorities, such as the Labour Inspectorate Body and the Greek Ombudsman. The former is competent to impose sanctions on the employer if there is a breach of the general prohibition of violence and harassment at the workplace and the obligation of employers regarding the prevention of such incidents and the obligation to adopt policies within the business. The Greek Ombudsman is competent to deal with disputes when there is violence or harassment in the workplace coupled with discrimination due to, for example, gender, age, disability, sexual orientation, religious beliefs, or gender identity. Moreover, the applicable legal framework[13] stipulates that victims of violence and harassment are entitled to lodge a report before the Labour Inspectorate Body and the Greek Ombudsman. This is in addition to the judicial protection he or she may seek and the internal investigation procedure to which he or she may have recourse, without specifying whether internal proceedings may be suspended before the regulatory bodies decide on the matter.

On the other hand, the National Transparency Authority and in certain cases the Hellenic Competition Commission are external reporting channels for employees reporting breaches of Union law. In such cases, L.4990/2022 (article 11 paragraph 5) stipulates that the investigation before the National Transparency Authority is not suspended if reporting procedures before other regulatory authorities have been initiated.

Moreover, criminal investigations can run in parallel with internal probes.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).

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 employer has an obligation, towards the alleged victim but also the alleged perpetrator, to carefully investigate the report and any existing evidence before making decisions. The employee under investigation must be informed about the outcome of the procedure and any measures adopted in this regard. The respective decision must have due justification.

Workplace investigations often result in an investigation report that is intended to serve as the basis for any measures to be taken by the company's decisionmakers.

The employee's right to information based on article 8, Swiss Federal Act on Data Protection also covers the investigation report, provided that the report and the data contained therein relate to the employee.[1] In principle, the employee concerned is entitled to receive a written copy of the entire investigation report free of charge (article 8 paragraph 5, Swiss Federal Act on Data Protection and article 1 et seq, Ordinance to the Federal Act on Data Protection). Redactions may be made where the interests of the company or third parties so require, but they are the exception and must be kept to a minimum.[2]

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 explicit legal provision stating the whole report must be communicated with the employee under investigation. The legal framework (L.4990/2022 and L.4808/2021) is governed by strict confidentiality obligations and obligations to protect the complainant’s data. From a data protection regulation perspective, it could be argued that the right of the person under investigation to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of such persons.

However, if the outcome of the investigation leads to the imposition of disciplinary measures, the right of the employee under investigation to request the whole investigation report, to aid in their defence is enhanced. Moreover, if a complaint is made in bad faith or is unfounded, it may be supported that the employee under investigation is entitled to receive full documentation so he or she can seek adequate legal protection or file an action before the courts.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

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.

For workplace violence and harassment investigations, depending on the outcome of the internal investigation, the employer may adopt certain measures including, for example, recommendations to the employee under investigation, changes to the employee’s working hours and transfer to another department.

If the employer decides to terminate the employment relationship, without having previously followed existing corporate policies regarding reporting procedures or without having provided the alleged perpetrator with the right to be heard, the dismissal could be deemed invalid. In any case, the measures adopted should be appropriate and proportional to the act committed.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.

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).

In principle, there is no specific obligation for investigating persons to disclose their findings. For proceedings before a court that have been initiated or investigated by the police or competent regulatory bodies, the relevant findings may be communicated under strict conditions and provided that the personal data of the parties involved are not publicly disclosed.

More specifically, under L. 4490/2022, in the context of whistleblowing procedures, personal data and any information that leads, directly or indirectly, to the identification of the complainant are not disclosed to anyone other than employees involved in the investigation, unless the complainant consents. The identity of the complainant and any other information may only be disclosed in the context of investigations by competent authorities or judicial proceedings, to the extent necessary for the protection of the employee under investigation’s rights of defence. Confidentiality obligations govern the procedure for revealing trade secrets to police and regulatory bodies, especially in the framework of L.4990/2022.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]

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.

Under the General Data Protection Regulation, employees’ personal details and information must be kept in the business records for as long as is necessary for the purposes of the employment relationship. Otherwise, stored data must be deleted. However, under L.4990/2022[14], reports remain in the relevant record for a reasonable and necessary time, and in any case until the completion of investigations or proceedings before the courts that have been initiated as a consequence of a complaint against the employee under investigation, the complainant or any third parties.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]

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.

The employee can contest the decisions of disciplinary councils before the courts and request their annulment. 

Moreover, in the framework of L.4990/2022, a monetary penalty and prison sentence (to be defined by an implementing Ministerial Decision) may be imposed on any person violating confidentiality obligations concerning the identity and personal data of employees or third parties included in the investigation procedure, while monetary penalties are also provided for legal entities[15].

Moreover, administrative fines may also be imposed if the employer does not comply with the legal requirements concerning the prevention of violence and harassment in the workplace.

Furthermore, the employee under investigation may initiate proceedings before the courts under tort law, by claiming compensation for moral damages suffered if the company did not comply with its confidentiality obligations after the incident (eg, due to the spread of rumours in the workplace). This may also be linked with criminal law proceedings against the persons responsible for dealing with the investigation (and not against the legal person, since under Greek law there is no criminal liability for legal persons).

On the other hand, the employer may also be exposed to liability vis-à-vis the complainant, witnesses or facilitators, for breach of confidentiality or other obligations prescribed in the respective legal provisions, or if there are retaliation measures.

As there are no specific regulations for internal investigations, the usual legal framework within which the employer must act towards the employee derives from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights.

But, for example, unwarranted surveillance could conceivably result in criminal liability (article 179 et seq, Swiss Criminal Code) for violations of the employee's privacy. Furthermore, errors made by the employer could have an impact on any later criminal proceedings (eg, in the form of prohibitions on the use of evidence).[1]

Evidence obtained unlawfully may only be used in civil proceedings if there is an overriding interest in establishing the truth (article 152 paragraph 2, Swiss Civil Procedure Code). Consequently, in each case, a balance must be struck between the individual’s interest in not using the evidence and in establishing the truth.[2] The question of the admissibility of evidence based on an unlawful invasion of privacy is a sensitive one – admissibility in this case is likely to be accepted only with restraint.[3] Since the parties in civil proceedings do not have any means of coercion at their disposal, it is not necessary, in contrast to criminal proceedings, to examine whether the evidence could also have been obtained by legal means.[4]

Unlawful action by the employer may also have consequences on future criminal proceedings: The prohibitions on exploitation (article 140 et seq, Swiss Criminal Procedure Code) apply a priori only to evidence obtained directly from public authorities. Evidence obtained unlawfully by private persons (ie, the employer) may also be used if it could have been lawfully obtained by the authority and if the interest in establishing the truth outweighs the interest of the individual in not using the evidence.[5] Art. 140 paragraph 1 Swiss Criminal Procure Code remains reserved: Evidence obtained in violation of Art. 140 paragraph 1 Swiss Criminal Procure Code is subject to an absolute ban on the use of evidence (e.g. evidence obtained under the use of torture[6]).[7]

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.
