Workplace Investigations

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.

There is no specific legislation governing workplace investigations in Turkish law. However, there are general principles stemming from Labour Law No. 4857 as well as good practice principles. Data protection laws also occasionally intertwine with these. The internal codes and policies of the company should also be followed throughout the process.

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]

The need to initiate an internal investigation may arise from the receipt of information from various sources. Reporting is one of the most common sources and can be in different forms. In Turkey, while conventional methods such as reporting to a direct supervisor, human resources or executives is quite common, whistleblowers also use reporting mechanisms such as web-based forms, telephone hotlines or e-mail, if such mechanisms exist. It is critical to obtain as much information as possible from the complainants at this initial contact, to make a sound decision on whether or not to commence an investigation. There is no requirement to decide to start an investigation and it can be commenced through a corporate resolution (eg, ethics committee resolution or board resolution) of a decision-making body or a decision of the body or person who has such authority under the company policies. The investigation team who will conduct the process may also be approved by the company's decision-making body. It is also advisable to have a preliminary inquiry for the complaints, before commencing a fully-fledged 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.

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

An employee can be suspended during a workplace investigation provided his or her prior written consent is obtained to this effect during or immediately before the investigation. Obtaining a generic written consent from the employee regarding suspension, which is not tied to a specific event, will not be valid. If there is a suspension of employment due to the workplace investigation, the obligations of the parties arising from the employment relationship continue, except for the employer’s obligation to pay a salary (and provide benefits, if any) and the employees’ duty to perform work.

There is no provision or established court decision setting forth the rules regarding the length of the suspension period; however, as a general rule, this period should be as brief as possible, so as not to cause any impression that the employment relationship has been terminated by the employer. Suspension of an employee on full pay during a workplace investigation, which is also known as garden leave, is a commonly used alternative to a conventional suspension method described above. During the garden leave period, an employee can be banned from entering the workplace and performing any of his or her duties either partially or entirely while continuing to be paid his or her regular salary, along with fringe benefits. Garden leave is not a concept regulated under Turkish employment legislation, but rather developed in practice, mostly by the Turkish subsidiaries of multinational companies. An ideal approach for the implementation of garden leave would be to obtain the written consent of the employees either at the commencement of employment or during the investigation.

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.

There is no compulsory requirement or qualification arising from the law as to the selection of the investigation team. The number and the profile of the investigation team need to be decided according to the characteristics of the case, whereas the head of the investigation team needs to be a competent and experienced investigator. A conflict of interest review is required to be conducted for the whole investigation team to protect the interests of the company. As conflicts of interest can also arise during an investigation process, relying on the support of an outside legal team should be considered, particularly for internal investigations that are likely to expand.

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.

There is no specific remedy provided under Turkish law to stop the investigation. One may consider requesting an injunction from a court for this purpose, but it is less likely that such a request would be successful. This is because investigations are often conducted for fact-finding purposes and to obtain an injunction the claimant will need to prove that this fact-finding exercise will pose a great risk and cause irreparable harm to the employee.

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]

Co-workers cannot be compelled to act as witnesses in a workplace investigation. Employees also have rights arising from the law that must be respected by the employers and investigators, such as the right to privacy or to remain silent, freedom of expression and communication. These rights must be protected during every step of the workplace investigation process.

When collecting physical evidence that contains personal information, the Personal Information Protection Law and its related guidelines apply. In addition, when collecting physical evidence that contains privacy information or an employee's photograph, care must be taken to ensure that the right to privacy and the image rights are not violated.

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 conditions applicable to gathering physical evidence mainly stem from the precedents of the Turkish Constitutional Court about employment disputes and the rules set forth under Turkish Law No. 6698 on the Protection of Personal Data (DPL). It is generally accepted that employers can gather physical evidence for certain legitimate purposes, such as disciplinary investigations, the prevention of bribery and corruption, fraud or theft, money laundering, and employee performance monitoring and compliance. In doing so, employers must, however, comply with the fundamental principles of the Turkish Constitutional Court as briefly described below:

• The grounds for the gathering of evidence must be legitimate. The definition of the legitimate interests of the employer may change depending on the characteristics of the business, workplace and employee job description, as well as the specific circumstances of the case. Therefore, it is advisable to carry out a balancing test between the legitimate interest the employer is seeking to protect and the employee’s interest in the protection of their privacy.
• The collection activities must be proportionate, in the sense that the measure implemented by the employer must be appropriate and reasonably necessary to achieve the legitimate purpose, without infringing upon the fundamental rights and freedoms of the employees. For instance, e-mail monitoring to collect evidence may not be proportionate if it is determined that e-mails that are not related to the incident subject to investigation are also accessed. To achieve this, certain keywords or algorithms can be used while monitoring e-mails during a disciplinary investigation.
• The collection process must be necessary to achieve the purpose. In other words, the collection of physical evidence must only be carried out to the extent there are no other measures allowing the employer to achieve its purpose, such as witness testimony, workplace records, or examining the results of projects. If the purpose can be achieved through less invasive means, the collection of physical evidence may not comply with the principles established by the decisions of the Constitutional Court.

Separately, depending on the type of physical evidence collected, the collection process may lead to the processing of the concerned employees’ personal data. Under the DPL, personal data collected in Turkey can only be processed if the explicit consent of the data subject is obtained; or the data is processed based on one of the exceptions to consent provided by the law. To the extent the data processing can be deemed to be based on the pursuit of a legitimate interest of the employer, it should also meet the following conditions:

• it should be the most convenient and efficient method to identify any employee wrongdoing to protect the legitimate interests of the company; and
• the data processing should not harm the fundamental rights and freedoms of the employees.

The employer should in any case comply with the obligation to inform employees before the processing of their data, through a privacy notice containing mandatory information required by the DPL.

In addition, as a general principle, the evidence-gathering process should always be conducted based on the assumption that the internal investigation can lead to litigation. Any evidence that will be used in litigation needs to have been gathered in compliance with the law. In both criminal and civil litigation, the courts will review each piece of evidence to confirm whether it was gathered through lawful methods and disregard any evidence that fails to comply with due process.

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]

There is no explicit answer to this question. However, it is important to make a distinction between employees’ possessions and files that are strictly personal and employees’ possessions and files that are found on devices or files provided for company use. For the first category, the employer does not have the right to search employees’ possessions and files. For the latter category though, justifications need to be established, by observing the requirements explained in question 7. Furthermore, the employers must also ensure that employees are fully and explicitly informed in advance of the monitoring operations, either through a provision included in the employment agreement, or in a separate notice or employee policy, the receipt of which should be duly acknowledged by the employee.

See question 4 regarding amendments to the Whistleblower Protection Act.

The person designated as a whistleblower response service employee must not divulge the name, employee ID number, or other information that would allow a whistleblower to be identified without a justifiable reason, and there is a criminal penalty of up to 300,000 yen for violating this duty of confidentiality.

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.

Although there is no specific legislation in Turkish law on whistleblowing, necessary mechanisms need to be implemented to ensure that whistleblowers and the whistleblowing process are kept confidential. In addition, whistleblowers must be encouraged and supported to be open about raising their concerns in good faith. A whistleblowing activity, when it amounts to raising a concern in good faith, must not be mistreated by the employer. Employers should also put in place protection mechanisms against the mistreatment of whistleblowers or retaliation towards them by other employees.   

See question 9 for the confidentiality obligations of a whistleblower response service employee.

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]

As a general practice, workplace investigations need to be kept confidential for the integrity of the process. In some cases, employees can specifically request their identity or involvement be kept confidential. In such cases, additional measures need to be taken to protect confidentiality. In any case, obligations and rights arising from the DPL and Labour Law must be respected and complied with by the employer and the investigation team.

There are no specific legal stipulations or requirements regarding information, etc, that must be provided to employees who are the subject of an investigation.

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).

Informing the employee under investigation on the subject, purpose and possible consequences of the investigation need to be evaluated by the investigation team before the interview. As a general principle, the interviewer is expected to share the information he obtained on the case with the employee, and ask for confirmation or clarification on these matters. The employee under investigation may be subject to an interview to gain information or as a confrontation if there is concrete evidence. If the evidence in hand is not based on concrete and material grounds, it would be more appropriate not to lead the interview to a confession, but inform the employee of the possible allegations. However, if the available evidence is based on concrete and material grounds, the interviewer may confront the interviewee by sharing the information that was gathered during the investigation in an attempt to obtain a confession.

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.

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 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.

It is possible to use NDAs in investigations.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

It is crucial to keep the events and facts of a workplace investigation confidential for the integrity of the process. It may be necessary to consider appropriate confidentiality measures to protect the complainant, mitigate risks, and preserve evidence. Damage to the confidentiality of the case can prevent the investigation team from bringing the case to a correct and complete conclusion. Although the labour legislation imposes a general confidentiality obligation on employees, NDAs can still be used as supplementary documents that may emphasise the confidentiality obligations of employees in workplace investigations and provide additional contractual protections such as penalties if there is a breach.

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.

Attorney-client privilege is attached at the time the attorney is hired as a legal representative. Attorney-client privilege, which is regulated under the Law of Criminal Procedure No. 5271 and the Attorney’s Act No. 1136, covers not only the investigation process, but also the legal advice and counselling received before and after the investigation. The importance of this privilege is especially present in cases where judicial or administrative authorities are involved in the process. Documents and correspondence benefiting from attorney-client privilege can be protected and fall outside the scope of preventive measures such as search and seizures due to the right of defence.

There is no legal right to have a legal representative present or appointed during the 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.

Yes, the employee under investigation has a right to be accompanied by his or her legal representative during the investigation. It is also essential that the employee under investigation is informed about his or her right to have a legal representative.

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.

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.

There is no legally established assistance programme.

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 involved in the investigation should be granted their personal needs (such as refreshments or access to the bathroom), as well as translation services or transportation, if needed. A breach of these rights or needs during the process may constitute a violation of the law and adversely affect the validity of the results to be obtained from the investigation.

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

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

If 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.  

Whether or not an investigation should be suspended when an employee under investigation files a complaint depends on the specific circumstances. There is no legal requirement to suspend the investigation.

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

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

If, during the investigation, the employee under investigation raises a grievance, the investigator will be expected to temporarily stop the investigation to assess the situation. The investigation team will evaluate whether the employee is raising a grievance as a defence mechanism or in good faith and with sincere concerns. If the subject of the grievance is related to the pending investigation, the investigation may be extended to cover this new item. Otherwise, a new investigation can be initiated by the investigation team.

The company will seek a physician's diagnosis and opinion and determine whether to proceed with the investigation. If an employee’s mental health suffers because of the investigation, the company may be charged with a violation of its duty of care.

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).

The employee’s participation in the investigation is vital for a fair assessment and to ensure that the employee has been allowed to defend himself or herself against the allegations. As such, every reasonable effort must be made by the employer to adjust the investigation process so that the employee can take part in the investigation. For example, if the employee goes off sick and thus cannot attend the investigation interviews or disciplinary hearings, the investigation should be carried out as much as possible without resorting to the employee in question, by initially exhausting the other available options (such as conducting interviews or disciplinary hearings with other available witnesses). However, if the employee’s absence takes longer than is reasonably expected or the matter at hand must be dealt with urgently, the employer may consider concluding the investigation and determining the next steps based on the information at hand. In such a case, it is recommended to explain in the investigation report the reasons why the employee could not take part in the investigation process (ie, why an interview or disciplinary hearing, etc, could not have been arranged with the employee) along with supporting documentation evidencing the employer’s efforts to involve the employee in the investigation process and the employee’s excuse for not participating interviews or disciplinary hearings.

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).

If the issues being examined during an investigation are also subject to parallel criminal or regulatory investigation, the workplace investigation will probably be stayed. This is primarily because parallel criminal or regulatory investigations would necessitate a more comprehensive examination and public bodies overseeing such investigations have a broader legal prerogative to gather evidence. It is, therefore, advisable to stay the internal investigation to not interfere with the criminal or regulatory authorities. If a prosecutor or a court requires the employer to give evidence or share certain documents, the police can compel the employer to share evidence. Regulatory bodies may also ask the employer to share evidence and the powers conferred on such regulatory bodies will be a determining factor in whether they can compel the employer.

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]

In general, the employee under investigation should be adequately informed about the allegations and findings to be able to defend him or herself. If no legal action will be taken against the employee under investigation as a result of the investigation, the employee may be notified regarding the findings and the outcome of the investigation. If the employee will be subject to a legal or administrative action (ie, warning, reprimand, or termination of employment), the formal requirements stemming from the Labour Law will need to be followed.   

There is no legal obligation to share reports of findings. Therefore, the company may share only the summary or the entire report at its discretion.

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

There is no legal requirement for the disclosure of the investigation report in full. If the investigation report needs to be submitted to the court, public institutions or other third parties, measures may need to be taken to protect confidentiality or to comply with the confidentiality requests of the persons participating in the investigation.

In an investigation into an employee's misconduct, based on the results of the investigation, disciplinary action will be considered if there are grounds for disciplinary action, and dismissal will also be considered. Personnel actions (eg, dismissal, reassignment) may also be taken.

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.

The employer may take various legal remedies against the employee whose infringement is discovered as a result of the internal investigation. Depending on the outcome of the investigation, the employer:

• may provide the employee with a written warning requesting him or her not to repeat the same conduct;
• terminate the employment relationship based on either just cause, without paying any compensation immediately, or valid reason by observing statutory notice periods or making payment in lieu of notice and paying severance compensation if applicable; or
• not take any action if the investigation concludes that no fault is attributable to the employee.

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]

Investigation reports may be disclosed in potential lawsuits or judicial proceedings. Therefore, the investigation report must demonstrate that a detailed and objective investigation has been carried out. Courts may also request that the interview records be disclosed to them, failing which, the courts may resort to an adverse inference in civil proceedings. Criminal courts can also ask the interview records to be disclosed if this would be necessary for reaching the truth. Failure to disclose may entail criminal responsibility under certain conditions.

Records related to responses to whistleblowing must be kept for an appropriate period, but there is no legal stipulation on the retention period. Each entity is required to set an appropriate period after considering the need for evaluation and inspection, and the handling of individual cases. There is no legally stipulated retention period for other investigation results.

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 provision in the legislation setting forth a specific duration for keeping the outcome of the investigation findings in personnel files. However, based on general principles, the outcome of the investigation can remain on the employee’s personnel files as long as the employer has a lawful interest in such processing without unnecessarily harming the privacy rights of the employee.

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 nature of legal exposure is very much dependent on the legal action the employer has taken after the investigation. The employer may be subject to a wrongful termination lawsuit to be filed by the employee, which may result in the payment of compensation to the employee of between eight and 12 months’ salary, if the court concludes that the termination is wrongful. This may also include monetary and moral damages claims. If no termination has taken place, the employee may terminate his or her employment with just cause if the employer has erred in its neutral fact-finding mission and this affects the employee. The employee may also file a criminal complaint to the extent that the investigation findings incriminate the employee in error.
