Workplace Investigations

Employers will generally take steps to treat complaints sensitively and confidentially. However, because of the obligations employers have, confidentiality cannot be guaranteed as part of the investigation and the complainant, respondent and witnesses should be made aware of this.

Understandably, the complainant or witnesses may wish to remain anonymous. However, because the details of the allegations need to be put to the respondent so that they can provide an informed response or explanation, the source of the information will often need to be disclosed.  

Employers can take steps to “ringfence” the investigation by asking employees to sign a confidentiality agreement. This will protect the interests of the participants of the investigation and uphold the integrity of the investigation.

When dealing with reports and persons covered by the HSchG, the provisions on identity protection must be followed. In all internal investigations, only authorised persons should receive information.

If the complainant made use of an internal whistleblowing procedure, confidentiality regarding the identity of a reporter is mandatory. Also, in other cases and for other involved persons (witnesses), it is recommended to keep their identity confidential to prevent the risk of intimidation or other negative consequences.

In complaints due to sexual harassment, violence or bullying at work, if the prevention adviser heard or took written statements from persons that were considered useful for the evaluation, these persons may remain anonymous.

The employee must, nevertheless, receive sufficient information to be able to offer a defence concerning the facts of which he or she is accused.

Yes, the identity of the complainant, witnesses and sources of information for the investigation should be kept confidential.

At the level of criminal procedure in PRC, only the Criminal Procedure Law of PRC provides that pseudonyms may be used in the indictment as a substitute for the disclosure of a witness's personal information, such as name, address, employer and contact information, to protect the personal safety of the witness. However, there are no relevant provisions on whether the identity of the complainant, the witness in civil litigation and the provider of information shall be kept confidential during an investigation.

During the course of an investigation, in order to protect the privacy of relevant personnel and avoid the risk of infringement, the employer usually keeps the identity of the complainant or the provider of investigation information confidential. However, at the civil litigation stage, the witness is unavoidably required to testify in court, and must truthfully identify himself/herself to the court.

See question 11, there is no protection of anonymity as the process must be transparent to the parties involved.

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.

There is no general obligation on the part of the employer to disclose to the employee concerned the identity of the complainant, witnesses or other sources of information during the workplace investigation.

However, as described in question 11, the employee must be sufficiently informed of the allegations before a termination based on suspicion of wrongdoing is issued. This may also require disclosing the complainant's or witnesses' identity or other sources of information. In addition, the employer would have the burden of proof in the context of a legal dispute (eg, termination protection proceedings or proceedings about the legality of certain investigation measures) and may have to name witnesses and disclose sources of information.

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.

Subject to any internal policies and terms of the employment contract, an employer would have discretion as to whether the identity of the complainant, witnesses or sources of information for the investigation should be kept confidential. In general, the employer should consider how the confidential treatment or its absence would affect the conduct and outcome of the investigation. The disclosure of the identity of the complainant in some cases may be necessary for the employee under investigation to respond in a meaningful way. On the other hand, both the complainant and witnesses may be more forthcoming in providing information if he or she is assured that his or her identity will not be made known to the person under investigation (especially if the latter is senior management personnel). A balance should be struck between the interests of the complainant or witnesses in maintaining confidentiality and the need for the employee under investigation to make a proper response to the allegations made. In any case, the employer should follow its whistleblowing policy if there is one (as discussed in question 9), and take into account practical and statutory considerations relating to confidentiality (as discussed in question 10).

The response and approach to this would be very fact-specific.

Under the SH Act, an individual cannot file an anonymous complaint and, therefore, the name of the complainant cannot be kept confidential. The same would go for details of witnesses, if any.

For other types of misconduct, the name of the complainant could potentially be kept confidential, depending on the nature of the allegations. For example, if an individual observes another colleague or employee committing inappropriate conduct (such as fraud or bribery) and reports this, the name of the complainant may not necessarily have to be disclosed to the accused employee, especially where the company is independently able to gather evidence substantiating the allegations. The names of witnesses generally cannot be kept confidential, since doing so may prove prejudicial to the accused employee. Further, as part of the disciplinary inquiry process, the accused has the right to cross-examine witnesses.

Notwithstanding the above, the approach to this issue should be assessed on a case-by-case basis by looking at the underlying sensitivities and risks involved. Courts have, in limited circumstances, permitted non-disclosure of the names of witnesses or complainants.

Failure by an employer to provide the identity of the complainant, witnesses or sources of information seriously impinges upon the employee's right to fair procedure and could result in a flawed investigation.

Yes, in principle the identity of the complainant, witnesses or sources of information for the investigation can be kept confidential.

On the other hand, if the employer – after having concluded the investigation – brings disciplinary action against the employee, the employer must send a letter to the employee in which the facts are described in detail, objectively and in a precise way, identifying when and where they have taken place, to allow a proper defence for the employee.

Even at this stage, however, the employer has no obligation to provide the employee with the evidence underlying the facts ascribed to him (ie, the employer has no obligation to specify the identity of the individuals through which they gained knowledge of the facts reported in the disciplinary letter).

However, if the employee subsequently challenges the disciplinary sanction before a judge, the employer bears the burden of proof, which may mean having to call the individuals interviewed within the internal investigation to stand as witnesses in court.

Moreover, in case of whistleblowing reports falling within the scope of the WB Decree, the employer is requested to generally keep the whistleblower’s identity confidential (according to art. 12 of the WB Decree). More specifically: (i) if the disciplinary charges are grounded on investigations which are different and additional to the whistleblowing report (although arising as a consequence of the report), the whistleblower’s identity may not be disclosed; (ii) if the disciplinary charges are grounded, in whole or in part, on the whistleblowing report, and knowing the identity of the whistleblower is indispensable for the defendant, such report may be used for the purpose of the disciplinary proceeding only if the whistleblower gives consent to his/her identity being revealed.

For whistleblowing investigations, whistleblower protection is required (see question 9).

Witnesses and other sources of information are not protected by the Whistleblower Protection Act.

In addition, as a response to a report of harassment, the Ministry of Health, Labour and Welfare guidelines require that necessary measures be taken to protect the privacy of the reporter, the offender, and others, and that these measures be announced to the company.

Such information can usually be kept confidential in an internal investigation, subject to potential disclosure obligations (see question 25). As indicated in question 10, depending on the nature and subject matter of an investigation, the identity of employees involved and investigative findings shall be shared with an employer on a need-to-know basis only. Specific requirements apply to the protection of the identity of whistleblowers since the Whistleblower Directive was implemented into Dutch law.

Typically, the identities of the complainant, witnesses and sources of information for the investigation are kept confidential.

The identity of the complainant, witnesses and sources of information may be kept confidential under the employer’s policies.

Yes.

An employee served a notice of accusation is entitled to assess all information that was gathered within the scope of the investigation and disciplinary procedure (notably the identity of the complainant, witnesses heard, other sources of information, etc), otherwise his right of defence may be jeopardised.

Where a preliminary investigation does not lead to an accusation against the employee, no disclosure has to be made by the employer.

Such information can be kept confidential, subject to questions 10 and 11. However, disclosure may nevertheless be compelled in court or arbitration proceedings as well as by disclosure requests or directions by the police or statutory authorities, including the MOM.

As discussed in question 1, if the whistleblower falls under the WPA, the whistleblower’s identity should be kept confidential. Even if the WPA does not apply, the company may wish to keep the identity of the whistleblower and other key witnesses confidential to the greatest extent possible.

As in question 10, the identity of the complainant or other employees involved in the investigation may be kept confidential and companies do not have to share their identity with investigated employees. Anonymous complaints are expressly allowed under Spanish law (see question 9).

Companies may have to produce this information and share it with the investigated employees if it is necessary to allow them to defend themselves from disciplinary measures taken against them. Similarly, in the context of litigation, an employee or plaintiff could request a Labour Court to order the company to disclose the details of the investigation.

If the Swedish Whistleblowing Act applies, their identity must be kept confidential under the duty of confidentiality. If the Swedish Whistleblowing Act does not apply, their identity can to a large extent be kept confidential.

It can also be noted that a workplace investigation carried out in the public sector will often (eventually) become an official document, which means that the document can be requested by the public. There are, however, provisions on secrecy that may restrict the right to gain access to official documents. These provisions are found in the Public Access to Information and Secrecy Act (2009:400).

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]

It is generally possible to keep the identity of the complainant, witnesses, or information sources confidential. There is no mandatory rule to disclose the identity of a complainant, witnesses, or sources of information. If the complainant, witnesses, or sources of information for the investigation know that their identities would not be disclosed, they will be more confident in cooperating with and supporting the investigations.

It is possible to keep such information confidential. If this is the case, the investigation team should conduct the interview outside the workplace of the company. This is actually good practice applicable to all internal investigations, unless there is a particular reason that requires the meetings to be held at the company.

Only in exceptional circumstances, such as where there is a genuine risk of retaliation. Anonymising a complaint puts the employee under investigation at a significant disadvantage, as they may be unable to properly challenge the evidence against them. It can also impair the effectiveness of the investigation. Employers should, therefore, not provide any guarantees of confidentiality to complainants or to employees who are to act as witnesses. That said, employers should think carefully about any necessary disclosure of names or facts. This can be particularly relevant where the witness is subordinate to the employee being investigated.

In general, except as provided above, depending on the seriousness of the complaint and investigation, the only persons who should be aware of it are the relevant individual in human resources or legal, and where different, the persons assigned to investigate. Although it may not be feasible to maintain absolute confidentiality in conducting an investigation depending on the nature of the allegations, investigators should exercise discretion at all times and, where possible, avoid identifying complainants, the subject of the investigation or witnesses by name where it is not necessary, and where doing so could be detrimental to the fact-finding process.

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.

A trade union does not have any right to be informed of, or involved in, an investigation by an employer. However, an employee may request that their support person is a trade union member or trade union representative. This is appropriate and should be permitted.

Employers should review the terms of an employment contract, policy or industrial instrument as this may contain terms regarding trade union involvement. In particular, heavily-unionised workplaces may contain enterprise agreements which contain relevant clauses.

The Austrian Labour Constitution Act (ArbVG) does not contain any provisions regarding workplace investigations. The employee has the right to address the works council but is not entitled to have the works council comply with his or her request.

The works council's opportunities for participation are conclusively regulated. Certain investigative or control measures may require the consent or co-determination of the works council.

Under section 96(1)3 ArbVG, the consent of the works council is required if the employer wishes to introduce and maintain control measures or technical systems for monitoring employees that affect human dignity, such as video surveillance or specific staff questionnaires. If there is no works council, the consent of each individual employee is required.

At the request of the involved employee, an employee can be assisted by a member of the trade union delegation, for example, during his or her hearing.

The works council should be informed of an investigation if there is a considerable impact on the company; this will only be the case if the investigation concerns a very serious, important or widespread issue. This information should be communicated as soon as possible and before measures are taken as a result of the investigation. This is only a right to information, not consultation. Moreover, members of the works council may be asked to respect their duty of confidentiality. However, as the enforcement of this duty of confidentiality is difficult, the timing of the information should be chosen wisely so it does not jeopardise the investigation.

No, there is no such right.

The relevant laws and regulations in the PRC have not expressly provided the employer’s obligation to inform the trade union of the internal investigation or the right of the trade union to participate in the employer's internal investigation. In practice, given the confidential nature of internal investigation, the employer usually does not voluntarily inform the trade union of such information. However, in accordance with Article 25 of the Measures for the Supervision of Labor Law by Trade Unions of the PRC, the trade union shall have the right to conduct an investigation if the employer has violated the labor laws and regulations or infringed the legitimate rights and interests of the employee. Therefore, it is still possible that the employer, in the course of the internal investigation, may be investigated by the trade union if it has violated the labor laws and regulations or infringed the legitimate rights and interests of the employee (e.g. being suspected of infringing personal information or privacy).

In addition, if the employer determines that the employee has committed a serious disciplinary offence based on the result of the internal investigation and thus decides to terminate the employment contract unilaterally, it shall notify the trade union of the reasons for termination in advance. If the employer has violated the laws, administrative regulations or the provisions of the employment contract, the trade union is entitled to request the employer to make corrections.

A works council or a trade union does not have a role in 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.

The works council does not have a general right of co-determination on whether and in what way a workplace investigation is carried out. However, workplace investigations may trigger co-determination rights of the works council in specific cases, as outlined below. If co-determination rights come into consideration, the employer must inform the works council about the investigation to put the works council in a position to assess whether or not co-determination rights are affected.

In connection with workplace investigations, the works council may have a co-determination right in the following cases:

• If e-mail accounts and data are screened by using technical devices that are suitable to monitor the behaviour or performance of employees (section 87 paragraph 1 no. 6, BetrVG).
• If, for example, the employer instructs all or a large group of employees to participate in interviews, the co-determination right of the works council regarding the rules of operation of the establishment and the conduct of employees in the establishment (section 87 paragraph 1 no. 1, BetrVG) may be affected.
• If standardised questionnaires are used in employee interviews, provided they are used for a large group of interviewed employees (section 94, BetrVG).

If co-determination rights exist in the specific case, the works council has the right to co-determine the type and structure of the specific investigative measures used (ie, the relevant investigative measure cannot be carried out without the works council's consent). To avoid any conflicts, the employer should set up, together with the works council, general rules about workplace investigations well ahead of any investigation.

Trade unions have no right of co-determination in workplace investigations.

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].

Unless the employment contract or the relevant internal policies specify otherwise, there is no automatic right under Hong Kong law for a works council or trade union to be informed or involved in a workplace investigation.

No.

There is no specific requirement to constitute a works council for most industries or inform the trade union about an investigation or disciplinary inquiry.

It is common, however, for individuals to share details of the matter with trade union representatives and seek their support. Further, if an employee has the right to be represented or supported by a colleague (for example, if the establishment is covered by the SO Act), the individual may request trade union representatives to support them during inquiry proceedings.

This will depend on the agreement with the works council or trade union. The employee who is the respondent to the investigation may have views on their trade union being informed, aside from any agreement, which should be taken into account under GDPR provisions.

Generally speaking, a workplace investigation does not require the involvement of a trade union (on the assumption that no specific union agreement has been reached at a company level to entitle trade unions to specific forms of consultation or involvement in workplace investigations, which is not common).

According to section 4 of the Workers’ Statute, as stated above, the involvement of the trade union is necessary regarding the installation and use of specific equipment (such as cameras, switchboards, software) that potentially allows the employer to remotely monitor working activity, and which can be done only with prior agreement of the unions (or authorised by the labour inspectorate).  The union agreement must be made before the installation of the system, and therefore would normally be already in place when an investigation starts.

Pursuant to the WB Decree (Art. 4), union representatives (or external unions) should be “heard” before the employer activates a WB reporting channel[1].

A labour union has no legal right to be involved in the investigation. However, if there is a provision in the collective bargaining agreement between the company and the labour union that allows the labour union to be involved in an investigation conducted by the company or to receive disclosure of the results of an investigation, then such a provision should be followed.

There is, in principle, no role for the works council in an "isolated or single" internal investigation. When it comes to structural forms of employee monitoring to measure behaviour (such as video surveillance), the proposed decision to implement such a monitoring system in principle requires the prior approval of the works council.

In addition, according to the Act on the Protection of Whistleblowers,  an employer who is not obliged to set up a works council needs the consent of more than half of the employees when adopting the internal reporting procedure under theAct, unless the substance of the procedure has already been laid down in a collective bargaining agreement.

The law is silent on whether a member of a trade union has the right to be informed or involved in the investigation. Typically, this is dependent on the employee’s contract, handbook or other policies of the employer.

Except if provided expressly under a collective bargaining agreement, the union does not have the right to be involved in the investigation. Given that the investigation is between the employee and the company, it follows that the union does not have any right to participate in the investigation proceedings.

There is no such obligation, unless it is provided for in an internal procedure or, for example, in the applicable collective bargaining agreement. It is neither a recognised practice nor recommended that such persons participate in the investigation.

However, in the event of violations that justify the termination of an employment contract with the employee, the employer should consult with that employee’s union about their intention to immediately terminate any employment contract concluded with that person or to terminate, with notice, the employment contract agreed with him or her for an indefinite term, or apply for consent to terminate the employment contract with an employee who is protected by a union.

Employee representative bodies are not entitled to be informed about or to participate in the preliminary investigation. The works council is only entitled to participate in disciplinary proceedings after a formal accusation has been made against the employee.

A copy of the accusation should be sent to the works council (if any) and if the employee is a trade union member, to the respective trade union. After the instruction phase of the procedure has ended (where the employer has to hear the witnesses identified by the employee in his written defence and file any other sources of information that have been requested), the employer should provide a copy of the disciplinary procedure to the works council (if any) and the respective trade union, if the employee is a member. These employees’ representatives will then have five business days to issue their opinion on the matter.

Finally, a copy of the final decision must also be sent to these bodies.

There is no legal right for the interviewee to be assisted by a representative from the works council.

An employee who is a member of a works council or trade union has the right to seek assistance from the works council or trade union representative (whichever is applicable) and have the works council or trade union involved in resolving the grievances.

For unionised companies, the grievance procedure and the role of the union representative are usually set out in the collective agreement entered into between the company and the works council or trade union. In some organisations, the employee handbook or grievance policy will also state when the trade union representative will be involved in the investigation process.

While a labour union does not have a legal right under Korean law to be informed or involved in the investigation, unless otherwise required under the relevant collective bargaining agreement, there have been instances where the labour union raised complaints that the company did not properly investigate an employee, who is a member of the labour union, particularly if the company took disciplinary action against that employee based on the findings of the investigation. The company should consider such a practical risk when conducting a workplace investigation.

If the investigation was conducted based on a claim filed by an employee to the Grievance Handling Committee (which is a sub-committee of a works council), the members of that committee have a right to be informed of the results of the investigation.

As explained in question 15, employees are not entitled to representation during an investigation. However, if a disciplinary procedure starts as a result of the investigation, employee representatives may be entitled to be informed of the disciplinary procedure and its outcome.

The degree and timing of when employee representatives must be involved will depend on several factors such as:

• the employee’s affiliation to a union;
• if the employee is an employee representative;
• the seriousness of the potential sanction to be imposed; and
• the information rights that the applicable collective bargaining agreement acknowledges regarding employee representatives.

No, but if the employee under investigation is unionised it is appropriate to inform the union about the investigation. If the employer chooses to take action against the employee during, or after, the investigation, the trade union generally needs to be consulted before any final decisions are made.

If the Swedish Whistleblowing Act applies, the employer is not authorised to inform a works council or trade union about the investigation, as it may be in violation of the duty of confidentiality (see question 10).

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.

Thai labor laws do not require a workplace investigation to involve participation from trade unions or labour unions. However, it is possible for labour unions established under the Labor Relation Act BE. 2518 (1975) to submit a demand for a collective bargaining agreement (CBA) with employers to get a seat at the table. There was a case where a management union made a CBA with the employer wherein the president of the management union would be involved in any investigation of any manager, who is a union member, under investigation. In that case, the employer must comply with the CBA by informing the president and allowing the president to participate in the investigations.

An authorized trade union, if any, may have the right to be informed or involved in the investigation, depending on the terms of the collective bargaining agreement in place. Even in the absence of such a provision in the collective bargaining agreement, it would still be recommended to inform the trade union of the investigation as a courtesy. We do not have works councils under Turkish employment law.

Aside from the statutory right to be accompanied (see question 15), any further involvement by the works council or trade union would depend on the terms of the relevant works council or trade union recognition agreement.

Employers generally have no obligation to inform employees of their right to union representation or to ask if they would like a union representative present during the interview. Union employees may insist, however, that a union representative attend any investigatory interview that could lead to the employee’s punishment, although the union representative may not interfere with the interview.

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.

During the investigation, unrelated matters can come to light, usually made by the complainant or a witness during the interview process. Unrelated matters may take the form of further complaints against the respondent (but on grounds that are outside the scope of the current investigation), or entirely different complaints.

An employer should first assess the nature of the new allegations. Entirely unrelated matters should be dealt with separately. However, if the matter relates to the respondent it may be appropriate to obtain consent from the respondent and complainant for the scope of the investigation to be widened. It is important to remember that all allegations must be put to the respondent and they must be given an opportunity to respond.

The employer must decide how to deal with this information. Possible options are to initiate separate and unrelated investigations or to extend the ongoing investigations.

If the investigation is not protected by confidentiality towards the employer (e.g. the prevention advisor cannot disclose confidential information to the employer), it could result in further measures taken by the employer or lead to a new investigation.

If unrelated matters are revealed as a result of the investigation, the company must be notified and must start a new investigation regarding them per the appropriate rules, without affecting the original investigation.

If any matter unrelated to this investigation is revealed during the investigation and the matter is suspected of violating regulations, the employer may comprehensively consider whether it is necessary to investigate the new matter. If the employer assesses that a combined investigation will seriously affect and hinder the progress of the investigation or complicate the investigation, the employer can handle the unrelated matters through separate investigations.

In addition, Article 6 of the Personal Information Protection Law of the PRC requires that the processing of personal information shall be for a specific and reasonable purpose and shall be directly related to the purpose of the processing and shall adopt the method with minimum impact on individuals' rights and interests. If the result of the investigation reveals unrelated personal information, it means that the collection and storage of such personal information are unrelated to the purpose of the processing. According to paragraph 1 of Article 47 of the Personal Information Protection Law of the PRC, the employer as the personal information processor shall take the initiative to delete personal information. If the employer fails to delete such information, the employee is entitled to request for deletion.

If they are related to the work or workplace, the employer will handle the emerging matters separately. In internal investigations, the employer is allowed to use any material legally available.

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.

There are no specific rules if unrelated matters are revealed during the investigation. If, in the course of the workplace investigation, new facts are discovered, the same principles apply as for the original reason for the investigation and the employer should consider whether to extend the investigation to the new matter too.

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.

If unrelated matters are revealed during the investigation, the employer should consider whether an investigation is needed. If yes, 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, it may not be appropriate to do so if different individuals are concerned or such inclusion would unduly complicate or delay the progress of the existing investigation. If that is the case, the employer should commence a separate investigation.

Where unrelated matters are revealed during, or because of, the investigation, the course to be adopted may depend on several factors. Normally, if additional instances of misconduct are revealed against the same accused employee, even if they are unrelated to the original investigation, it would be advisable to independently investigate those issues too, to ensure that there are comprehensive grounds for any future disciplinary inquiry or action. If unrelated matters are revealed against other stakeholders involved in the investigation – for example, a forensic review reveals that the complainant or some witnesses have themselves potentially engaged in some other form of policy breach – whether or not those issues are investigated (as well as the timing of such investigation) would need to be decided on a case-by-case basis. Issues to consider include whether these matters affect the credibility of their statements, point at some form of other conspiracy, or create the risk of retaliation claims at a later date.

In SH matters, however, if the complaint involves instances of sexual harassment as well as other forms of general harassment or misconduct, to the extent such other issues aren't linked to the instances of sexual harassment (eg, creation of a hostile work environment for the complainant), these other concerns should preferably not be investigated by the IC and instead should be referred to the employer to address, as per its general grievance-redressal mechanisms.

If an investigator finds other issues that are outside the scope of the terms of reference, these should not be ignored but equally should not be included as part of the investigation, as they are beyond the remit of the investigation that was established at the beginning. An investigator should identify the other matters that may require further action and report these to the employer separately so as not to conflate issues.

If further misconduct (unrelated to the investigation matters) is revealed, the company may start a new investigation.

Furthermore, even if the employee has a contractual duty to provide the information requested by the employer, one limit to this principle could be, for example, self-incriminating statements of the employee acting as a witness. However, if an employee nevertheless makes self-incriminating statements, the company could decide to start a new investigation.

Even if a matter arises that is not subject to the investigation, it can be used as an opportunity to conduct another investigation.

If the investigation yields unrelated matters, the employer will need to decide whether such matters should be followed up in the same or a separate investigation. If such matters include new allegations against an employee that are already involved in the investigation, the employer should, before interviewing (or at the start of such an interview) inform the implicated employees of the relevant new allegations that are the subject of the investigation.

Where unrelated matters are revealed as a result of the investigation, the body investigating the employee is expected to inform the employee of the new matters and give him adequate time to respond.

However, there are exceptional cases where a crime is revealed during an investigation. In such instances, the employer is required to report its findings to the police for investigation and possible prosecution.

If unrelated matters are revealed because of a workplace investigation, the employer may look into the new matter and then determine whether there are sufficient grounds to proceed with an administrative disciplinary process for the new matter.

It depends on the circumstances of the revealed issue and the employer’s compliance culture. Normally, if a new issue is revealed during the investigation, it should be analysed and investigated if appropriate.

If new facts arise as a result of the investigation and they are relevant, the employer may include them in the accusation. If, however, the new facts are revealed after the accusation has been served, the employer will have to prepare an addendum to the initial accusation and the employee will be able to use the same defence rights against that addendum.

If unrelated matters that require further investigation are revealed as a result of the investigation, the employer should take the necessary steps to investigate these matters, where relevant, under the employer’s grievance reporting, investigation and disciplinary processes. This should be done separately and independently from the existing investigation. Please note that section 424 of the Criminal Procedure Code imposes a legal duty on any person who is aware that another has committed certain specified offences to "immediately" report the matter to the police, "in the absence of reasonable excuse" not to do so. Failure to comply with this requirement is punishable with imprisonment for up to six months, and/or a fine.

Sometimes, the company discovers other potential misconduct in addition to the specific allegations that trigger a workplace investigation. No law limits the scope of the company’s investigation to the allegations that were initially raised.

The issue with revealing unrelated matters to the investigation is that it may jeopardise the entire enquiry. If the unrelated matters are private or the disclosure is construed as a breach of employees’ fundamental rights, then the materials gathered during the investigation could be considered to be unlawfully obtained and would not be admitted as evidence in court.

Moreover, the employee could seek damages and a fine could be imposed on the company for breaching its employee’s rights.

Finally, if unrelated matters are revealed, it could be a clear sign that the company has failed to conduct a diligent investigation and use the least intrusive means available to it (see question 1). One of the reasons to minimise the number of employees conducting the investigation (see question 4) is to reduce damages if matters unrelated to the investigation are revealed.

According to the GDPR, personal data can only be processed for specified, explicit and legitimate purposes and may not be further processed in a manner that is incompatible with those purposes. This imposes restrictions on the use of material from previous investigations in new investigations when the material was collected for other purposes. It is, therefore, necessary to ensure whether the new matter relates to the investigation and falls within the purpose of the investigation. If the new matter is unrelated to the investigation and does not fall within the purpose of the investigation, the identified information may not be processed under the GDPR.

Except for what is stated above, no regulation limits how the employer can use information regarding unrelated matters. Unrelated matters may be a myriad of different things, and could in some instances just be discarded, while in other situations the information may invoke a responsibility to act for the employer (eg, if the unrelated matters concern work environment issues or other severe misconduct by an employee who is not the target of the investigation). Furthermore, the employer may always use any revealed information (unrelated or not) as evidence in a court of law, since the principle of free examination of evidence applies.

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.

Subject to the grievance protocol in place, any matter that emerges during the investigation should be handled separately as a fresh report of potential misconduct that needs further investigation.

If an unrelated matter is revealed during the investigation, an independent assessment needs to be made as to whether this new matter requires to be included in the same internal investigation, or a separate/new one should be commenced.  

These should typically be disregarded by the investigator. From a data protection perspective, the ICO’s position is that other information collected during an investigation should be disregarded and, where feasible, deleted unless it reveals information that no reasonable employer could be expected to ignore. In those circumstances, the employer should arrange for an independent third party to determine whether a separate investigation into unrelated matters is needed.

Where new issues or claims arise during an ongoing workplace investigation, the investigator should discuss with in-house counsel whether the new issues or claims should be separately investigated and if so, by whom, or if instead those new issues or claims are sufficiently related to the current review that they can be investigated in parallel and incorporated into the ongoing fact-gathering process. 

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.
