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

There is no specific legislation, guidance or policies covering investigations in the workplace. Issues such as the Personal Data Protection Law, invasion of privacy, and infringement of freedoms may arise regarding the related parties, subjects, methods, and results of investigations. In addition, court decisions have stated that "when there has been a violation of corporate order, an investigation of the facts may be conducted to clarify the nature of the violation, issue business instructions or orders necessary to restore the disturbed order or take disciplinary action against the violator as a sanction”. The investigation or order must be reasonable and necessary for the smooth operation of the enterprise, and the method and manner of the investigation or order must not be excessive or restrain an employee's personality or freedom. In such a case, the investigation may be considered to be illegal and may constitute a tort.

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.

The Labour Protection Act B.E. 2541 (1998) (LPA) is the key legislation governing the relationship between employer and employee in Thailand. The LPA set out a minimum standard for the protection of employees’ rights, as well as a mechanism for suspension from work for an investigation.
The LPA requires any employer having ten or more employees to prepare work rules in the Thai language and the work rules require an employer to prescribe a procedure for the submission of grievances that would normally include the process for investigations in the workplace. Therefore, the work rules are the main guidance and policy that govern a workplace investigation. In some cases, an employer may have a whistleblowing policy allowing whistle-blowers to submit complaints of illegal or improper activities to the employer. The whistleblowing policy will also prescribe the procedures for investigating in workplace reflecting the complaints submitted by whistle-blowers.

The trigger for an investigation in the workplace may be:
- when an employee makes a report (eg, a report of harassment, a report of misconduct by another employee, etc);
- when an investigation is conducted by the Labour Standards Inspection Office or another regulatory agency;
- when a criminal or illegal act is discovered in the workplace; or
- when an internal audit conducted by the company reveals a problem.

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]

Usually, a complainant submitting a grievance to the company would be a trigger for proceeding with a workplace investigation. The LPA does not specify when a workplace investigation should commence but it is subject to the employer’s work rules and regulations, including the whistleblowing policy, as the investigation usually commences after an employee or a whistle-blower has filed a complaint to the employer. In some cases, there might be a whistleblower and the start of the workplace investigation would be subject to the whistleblowing policy and the employer’s discretion. Also, if a questionable transaction or activity is detected, fiscal audits may be the source that triggers a voluntary workplace investigation.

Court precedent states that a valid requirement for a stay-at-home order is it “would not be considered to put employees at a legal disadvantage (deprive them of their rights and imposes obligations on them), except in exceptional cases where employees are legally entitled to request work, unless there are special circumstances such as discrimination in salary increases and the like." (Tokyo High Court decision 25 January 2012, All Japan Mariners' Union). Therefore, it is considered possible to order the employee to stay at home during the investigation period if necessary. Some companies stipulate in their work rules that they may order employees to take special leave or stay at home when an incident occurs that could be the subject of disciplinary action.
In principle, the payment of salary in full during the stay-at-home period is required. However, work rules may stipulate that an employee will not be paid during the investigation period, and in cases where the employee is clearly responsible and it is inappropriate to allow the employee to work (eg, where it is almost certain that the employee has embezzled money on the job), the employee may be ordered to stay at home without pay. In addition, if the work rules stipulate that an absence allowance under the Labour Standards Law (60% or more of wages) must be paid for the stay-at-home period, such an allowance may be paid under the said rules.

While an employee is being investigated by the employer, the LPA permits the employer to suspend that employee from work for the duration of the investigation, provided that the suspension can only be made when permitted by the work rules or an agreement related to the conditions of employment. Also, a suspension order must be made in writing and specify the offence and period of the suspension, which may not exceed seven days. Note that the employer must give a written suspension order in advance to the employee before the work suspension.
As aforementioned, the LPA only permits the employer to suspend the employee under investigation from work only for seven days. During the interim period of the suspension, the employer must pay the employee at the rate indicated in the work rules or the agreement reached between the employer and the employee, which must not be less than half of the employee's wages for a working day before his or her suspension. If the employer determines that the employee subject to investigation is not guilty following the outcome, the employer must compensate the employee for outstanding wages from the date of suspension with 15% interest per annum.
In some complicated cases, a workplace investigation does not conclude within seven days, and, in which case the employer should consult with a legal advisor.

There are no specific qualifications or requirements for an investigator. In many cases, the investigation is handled by a department or employee as deemed appropriate by the company. In some cases, an outside attorney may be asked to handle the investigation. Also, when it is a serious matter for the company, a third-party committee may be formed and commissioned to conduct an investigation.
However, under the revision of the Whistleblower Protection Act, which came into effect in June 2022, entities employing 300 or more employees must designate a person (whistleblower response service employee) in charge of accepting internal whistleblowing reports, investigating internal whistleblowing reports, or taking corrective measures as a whistleblower response service provider. Entities with less than 300 employees must also make an effort to do the same.
The person designated as a whistleblower response service provider must not divulge the name, employee ID number, or other information that would enable whistleblower identification without a justifiable reason. Criminal penalties (fines of up to 300,000 yen) have been established for violations of this confidentiality obligation.

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.

The employer should conduct a workplace investigation on its own; however, an outside firm experienced in interviewing witnesses and assessing the credibility of evidence may also be appointed to assist with the workplace investigation.
There is no minimum qualification or criteria provided under Thai laws. It is worth noting that anyone who has been accused of misconduct or potentially has a conflict of interest should be excluded from any role in the investigation. This is to avoid a challenge from the subject employee that the investigation was not conducted fairly.

There are very few cases in which an employee subject to an investigation can file a legal proceeding to have the investigation stopped. Theoretically, an employee may be able to file a lawsuit or a provisional disposition to stop the investigation if he or she has a legal right to request that the company stop the investigation, but usually a lawsuit or a petition for a provisional disposition alone will not stop an investigation from proceeding. Although a provisional injunction would conclude in a relatively short period, such a provisional injunction would be unlikely to be issued if the investigation is conducted properly.

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.

Interviewing co-workers is often conducted in internal investigations. Company employees are generally required to cooperate with company investigations, especially those who are in a position to instruct and supervise employees, or those who are responsible for maintaining corporate order, since cooperation with an investigation is itself the fulfilment of their duty to the company. Other employees are not compelled to cooperate with such an investigation unless it is deemed necessary and reasonable. No specific legal protection is provided for testifying in an investigation.

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]

Normally, the work rules prescribe requirements for cooperation with investigations. An employer may instruct co-workers to give statements as witnesses as this would be a fair and legitimate order of the employer, because investigations are conducted to maintain a good working environment.
Witness protection measures in a workplace can vary as no minimum standard has been set and they are generally subject to work rules and regulations. However, some legislation, which may not relate to a workplace investigation conducted by an employer, also protects the witnesses who are helping authorities investigate violations under the relevant acts. For example, the Labor Relation Act B.E. 2518 (1975) prohibits an employer from terminating an employee or conducting any action that may result in the employee being unable to work because of filing a complaint or being a witness for the authorities, or providing information on issues related to labour protection laws to the authorities.
The employer may have a policy of non-retaliation for the protection of witnesses who have given statements and evidence for a workplace investigation.

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.

The basic premise is that all evidence is admissible unless it violates the law of admissibility and production of evidence, which may vary depending on the jurisdiction. In a criminal court, for example, evidence gathered in violation of the fruit of the poisonous tree doctrine would be typically inadmissible, yet in a civil court, this doctrine would not be an exclusionary rule.
The Personal Data Protection Act, BE 2562 (2019) (PDPA), which is the main data protection law in Thailand, applies when collecting, using, and disclosing pieces of evidence containing the personal data of employees. If the investigation requires sensitive information of the employee under investigation, for example, race, ethnic origin, political opinion, religious or philosophical beliefs, sexual behavior, criminal records, health data, disability, genetic data and biometric data, consent from the employee should be obtained.

Since inspections of personal belongings may potentially undermine employees' fundamental human rights, they would not become lawful simply because they are conducted under employment regulations.
Inspections of personal belongings must be conducted uniformly among employees in the workplace based on reasonable grounds, in a generally reasonable manner and to a generally reasonable degree, and based on the work rules, etc.
When inspections of personal belongings are conducted under employment regulations, etc, employees must agree to the inspection except in special circumstances, such as the method or degree of the inspection being unreasonable.
On the other hand, an investigation of information stored on a company network system may constitute an infringement of the right to privacy. If there is a provision in the employment regulations regarding the use of the internet and monitoring, it is possible to investigate under such a provision. A Japanese court case on the illegality of reading e-mails in the absence of a monitoring provision stated that private use of e-mails also carries a certain right to privacy, but also stated that "considering the fact that the system is maintained and managed by the company, the protection of the employee's privacy can only be expected within a reasonable range according to the specific circumstances of the system," and that the act of reading e-mails was not illegal because the extent of private use of e-mails was beyond the limit, which was outside the reasonable range of socially accepted ideas. The court also ruled that the monitoring of the employee's abusive private use of e-mail, which was discovered in the course of an investigation of slanderous e-mails within the company, was not illegal because even if the monitoring was conducted without notice, there was suspicion of a violation of the duty of devotion to duty and corporate order. The court also stated that the investigation was necessary and that the scope of the investigation did not exceed its limit.

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]

Electronic information created during employment would generally be owned by the employer and would be the employer’s assets. If an employee is given a computer or laptop to use for work, the employer has the right to log into that device and take any data that is stored therein, provided that the data does not contain sensitive information of that employee and PDPA requirements are met.
To avoid any potential issues regarding physical data such as documents on the employee’s desk, it is advisable to search those areas with the subject employee to show good faith. In practice, the employee normally agrees to search those areas with the employer, or allows the employer to search alone.

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 down to the employer’s discretion and subject to the whistleblowing policy (if any) to commence the investigation resulting from a complaint from a whistleblower. Whistleblowers and those who cooperate with an investigation should be protected. Normally the employer would not try to identify the whistleblowers. Also, it is best not to reveal the identity of the witness or the source of information; otherwise, they may feel uncomfortable giving information or raising their concerns next time. Any allegations of retaliation that surface during the investigation should be treated as a new report of possible misconduct that could be subject to additional investigation.

Other than the above, there is no specific legal obligation to maintain confidentiality for persons in charge of investigations, etc. However, if the information falls under the category of confidential information obtained by employees in the course of their work, compliance is required as an obligation attached to a labour contract, and many employment regulations stipulate a duty to keep information obtained in the course of work confidential.

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]

Unless the investigation is handled by a qualified professional (eg, attorney or auditor) where certain privileges apply, confidentiality obligations are generally subject to the contractual arrangement between the parties involved in the investigation. The employers need to inform any persons, including the investigators, to respect confidentiality obligations because a leak of the information gathered from the investigations could cause damage to relevant parties.

As a result of the employer's duty of care (article 328, Swiss Code of Obligations), employees under investigation have certain procedural rights. These include, in principle, the right of the accused to be heard. In this context, the accused has the right to be informed at the beginning of the questioning about the subject of the investigation and at least the main allegations and they must be allowed to share their view and provide exculpatory evidence.[1] The employer, on the other hand, is not obliged to provide the employee with existing evidence, documents, etc, before the start of the questioning.[2]
Covert investigations in which employees are involved in informal or even private conversations to induce them to provide statements are not compatible with the data-processing principles of good faith and the requirement of recognisability, according to article 4 of the Swiss Federal Act on Data Protection.[3]
Also, rights to information arise from the Swiss Federal Act on Data Protection. In principle, the right to information (article 8, Swiss Federal Act on Data Protection) is linked to a corresponding request for information by the concerned person and the existence of data collection within the meaning of article 3 (lit. g), Swiss Federal Act on Data Protection. Insofar as the documents from the internal investigation recognisably relate to a specific person, there is in principle a right to information concerning these documents. Subject to certain conditions, the right to information may be denied, restricted or postponed by law (article 9 paragraph 1, Swiss Federal Act on Data Protection). For example, such documents and reports may also affect the confidentiality and protection interests of third parties, such as other employees. Based on the employer's duty of care (article 328, Swiss Code of Obligations), the employer is required to protect them by taking appropriate measures (eg, by making appropriate redactions before handing out copies of the respective documents (article 9 paragraph 1 (lit. b), Swiss Federal Act on Data Protection)).[4] Furthermore, the employer may refuse, restrict or defer the provision of information where the company’s interests override the employee’s, and not disclose personal data to third parties (article 9 paragraph 4, Swiss Federal Act on Data Protection). The right to information is also not subject to the statute of limitations, and individuals may waive their right to information in advance (article 8 paragraph 6, Swiss Federal Act on Data Protection). If there are corresponding requests, the employer must generally grant access, or provide a substantiated decision on the restriction of the right of access, within 30 days (article 8 paragraph 5, Swiss Federal Act on Data Protection and article 1 paragraph 4, Ordinance to the Federal Act on Data Protection).

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

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

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]

There is no mandatory rule to disclose the identity of a complainant, witnesses, or sources of information.

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

There are no specific laws or rules for the provision of confidentiality privileges other than that provided by the Fair Trade Commission Rules, which allow companies that are the subject of investigations into cartels, bid rigging, etc, to treat communications with their lawyers as confidential. However, when a motion for an order to produce documents is filed in a court proceeding, if the requested documents are "documents exclusively for the use of the possessor of the documents", the obligation to produce the documents is not recognised. If the investigation materials fall under this category, it is possible to exclude them from the scope of the court order to produce documents.

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.

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.

Unless the work regulations provide otherwise, an employee has the right to request legal representation during an investigation. If legal representation is requested, it is an opportunity for the employer to confirm and verify that an investigation is being conducted fairly, as the employee under investigation can bring his or her lawyer to attend the investigation.

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.

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.

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]

The employees may then file a complaint with the labour inspection officer of the Labour Protection and Welfare Department to investigate the situation if they view that the conduct of the employer in the investigation violates the LPA. For example, if the employer issues a written order for suspending an employee for more than seven days. The labour inspection officer may issue an order requesting compliance, where failure to comply with such an order would result in a criminal penalty.

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 investigator should guide the employee who has raised the grievance to properly raise their concerns through the grievance protocols or whistleblowing policy (if any). It is acceptable to preliminarily hear their concerns, but the investigation should be initiated separately and subject to the employer’s discretion.

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).

If the absence is anticipated to be brief, the employer may wait until the employee's return before concluding the investigation. If the employee's absence is expected to be prolonged, the investigator may alter the time of meetings or request that the employee submits a witness statement. The key point would be that all necessary measures should be taken to give the employee a chance to participate.

It is possible to proceed with an investigation of a company even if there are concurrent criminal proceedings. It is up to the company to decide whether or not to proceed. The company may submit collected evidence collected to the police. The police will rarely disclose or provide the company with evidence they have collected. Usually, upon request by the police or regulator, the workplace investigation would be stayed. The police or regulator has to take legally required steps if compelling the employer to share evidence.

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).

Employers are not required to wait until the police or regulatory investigations are finished before conducting their disciplinary investigations, but it is necessary to ensure that such internal proceedings do not compromise the integrity of an investigation or result in misrepresentation or a miscarriage of justice. The level of proof for internal disciplinary action is less than the level of proof for criminal proceedings.

Although there is no legal obligation to report the results of the investigation to the employee, when taking disciplinary action it is generally necessary, from a due process point of view, to explain the facts of the disciplinary action and the results of the investigation, and to allow the employee to explain him or herself. Particularly in the case of serious disciplinary actions such as dismissal, failure to provide an adequate opportunity for an explanation is a possible ground for denying the validity of the disciplinary action.

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]

There is no mandatory information on the outcome of an investigation that must be disclosed to an employee. However, disclosure of the outcome should, at a minimum, include whether an employee did or did not commit a violation. In addition, an employee who has committed a violation should be informed of any disciplinary action, and the grounds for such a decision (such as a violation of the company’s work rules). This enables the employee under investigation to appeal the outcome if it is applicable under the work rules or whistleblowing policy.

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.

Upon completion of the investigation, the employer can decide to take proper disciplinary action against the employee if it is found that the employee committed an offence or violated the work rules. An employer may also file a report with the police if the findings of the investigation amount to a criminal offence.

If it is information related to a crime, and if it is necessary to report it to the supervisory authority, it is necessary and possible to report it even if the content relates to personal information. There is no obligation to report to the police even if one is aware of a criminal fact. However, it is possible to use the results of an investigation to file a complaint or charge with the police. It is also possible to use the results of the investigation to realise the company's rights (eg, to claim damages based on tortious behaviour).

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]

The investigation findings should be disclosed to a limited group of persons who are involved in the investigation, and for which the findings are useful. For example, an HR manager who needs to record the findings in the employee’s record, the police if the employer decides to proceed further with a criminal claim, the court if requested by that court, or if there is a court case related to the violations of the employee.
Interview records should be kept confidential and private. There is a risk of disclosure because the information in the records may be beneficial to one but damaging to others. If the interview records are leaked to others who are not involved in the investigation, it may affect the work environment in the workplace and the protection of witnesses.

Records related to responses to whistleblowing must be kept for an appropriate period, but there is no legal stipulation on the retention period.

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]

There is no period required by law for keeping the outcome of the investigation on the employee’s record. However, if termination of employment is the outcome of the investigation, an employer should keep details of the investigation for at least 10 years, in line with the prescribed period for an employee to file an unfair dismissal claim against an employer. An employer may use the details of an investigation to defend such a claim. For other disciplinary action, the retention of investigation details on the employee’s record is at the employer’s discretion.

If the company deviates from appropriate social rules in its investigative methods and means, it will be liable for tortious behaviour. If disciplinary action or dismissal is taken based on erroneous investigation results, the validity of such action or dismissal will be denied, the employee will be able to claim for back wages, and, in some cases, claim for compensation.

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 Thai Supreme Court has ruled that the termination of an employee was unfair due to an investigation being conducted contrary to requirements in the company’s work rules. As such, employers may be liable for damages to employees if there are errors made during investigations, or where investigations are not conducted properly.
The Supreme Court has also ruled that in cases of unfair termination, the underlying cause of the termination should be the determining factor, rather than other issues, including investigative procedures.
