Workplace Investigations

Mainly, the Occupational Safety and Health Act (738/2002). In addition, the following also have relevance in connection to a workplace investigation: the Employment Contracts Act (55/2001), the Criminal Code (39/1889), the Act on Occupational Safety and Health Enforcement and Cooperation on Occupational Safety and Health at Workplaces (44/2006), the Act on Equality between Women and Men (609/1986) and the Non-discrimination Act (1325/2014). In addition, the employer's own policies must be taken into consideration while conducting a workplace investigation.

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.

When the employer becomes aware of possible misconduct, the employer must commence an investigation immediately, in practice within about two weeks. The information may come to the employer's knowledge via, for example, the employer's own observations, from the complainant or their colleagues or an employee representative.

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.

There is no legislation on temporary suspension in the event of a workplace investigation or similar. In some situations, the employer may relieve the employee from their working obligation with pay for a short period.

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.

The employer must conduct the investigation, but the actual work can be done either by the employer's personnel or by an external investigator, for example, a law firm. Either way, there are no formal criteria for the persons executing the investigation; however, impartiality is required from the person conducting 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 employee does not have a legal right to stop the investigation. The employer must fulfil its obligation to investigate the alleged misconduct.

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.

There is no legislation on a witness's role in investigations. However, the legislation on occupational safety requires that employees must report any irregularities they observe. Depending on the situation, participating in the investigation may also be part of the person's work duties, role or position, in which case the employer may require the employee to contribute to clarifying the situation. However, there is no formal obligation to act as a witness, and there is no legislation regarding the protection of witnesses. If a witness wishes, they may have, for example, an employee representative as a support person during the hearing. 

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.

Generally, the basic principles set out by the GDPR and the Finnish Data Protection Act apply to data processing in connection with investigations, including evidence gathering: there must be a legal basis for processing, personal data may only be processed and stored when and for as long as necessary considering the purposes of processing, etc.

Additionally, if physical evidence concerns the electronic communications (such as emails and online chats) of an employee, gathering evidence is subject to certain restrictions based on Finnish ePrivacy and employee privacy laws. As a general rule, an employee’s electronic communications accounts, including those provided by the employer for work purposes, may not be accessed and electronic communications may not be searched or reviewed by the employer. In practice, the employer may access such electronic correspondence only in limited situations stipulated in the Act on Protection of Privacy in Working Life (759/2004), or by obtaining case-specific consent from the employee, which is typically not possible in internal investigations, particularly concerning the employee suspected of wrongdoing.

However, monitoring data flow strictly between the employee and the employer's information systems (eg, the employee saving data to USB sticks, using printers) is allowed under Finnish legislation, provided that employee emails, chats, etc, are not accessed and monitored. If documentation is unrelated to electronic communications, it also may be reviewed by the employer. Laptops, paper archives and other similar company documentation considered "physical evidence" may be investigated while gathering evidence on the condition that any private documentation, communications, pictures or other content of an employee are not accessed.

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.

Only the police can search employees' possessions (assuming that the prerequisites outlined in the legislation are met).

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.

In respect of data protection, the processing of personal data in whistleblowing systems is considered by the Finnish Data Protection Ombudsman (DPO) as requiring a data protection impact assessment (DPIA).

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.

Concerning a workplace investigation, there is no specific legislation in force at the moment regarding confidentiality obligations. All normal legal confidentiality obligations (eg, obligations outlined in the Trade Secrets Act (595/2018)), and if using an external investigator, the confidentiality obligations outlined in the agreement between the employer and the external investigator, apply. Attorneys-at-law always have strict confidentiality obligations as per the Advocates Act (496/1958).

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.

The process must be transparent and impartial, and therefore all the information that may influence the conclusions made during the investigation should be shared with the employee.

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

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

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.

Yes, however, the need for an NDA is assessed always on a case-by-case basis.

It is possible to use NDAs in investigations.

The privilege of investigation materials concerns a rather limited amount of cases. In practice, materials may be considered privileged in connection with the litigation process under the Procedural Code (4/1734). For example, communications between a client and an attorney may attract protection against forcible public 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.

The employee under investigation has a right to have a support person present (eg, a lawyer or an employee representative) during the hearings and a right to assistance in preparing written statements.

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

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

They can request assistance, for example, from an occupational health and safety representative, a shop steward or the occupational healthcare provider.

There is no legally established assistance programme.

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

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

If the nature of the grievance relates to the employer's obligations to handle such matters in general, the grievance will be investigated either separately or as a part of the ongoing investigation.

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.

As a general rule, sick leave does not prevent an investigation from progressing. Depending on the nature of the sickness, the employee can attend hearings and take part in the procedure. If the sickness prevents the employee from participating, the employer can put the process on hold temporarily.

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.

Regardless of a possible criminal investigation, the employer must run its internal workplace investigation without unnecessary delay. A workplace investigation and a criminal investigation are two separate processes and can be ongoing simultaneously, so the criminal process does not require the workplace investigation to be stayed. Thus, parallel investigations are to be considered as two separate matters. The police may only obtain evidence or material from the company or employer if strict requirements for equipment searches are met after a request for investigation has been submitted to the police.

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 employer's conclusions from the investigation.

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.

The employee under investigation may only be informed of the conclusions.

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.

The employer decides whether misconduct has taken place or not. Depending on the case, the employer may recommend a workplace conciliation in which the parties try to find a solution that can be accepted by both sides. The employer may choose to give an oral reprimand or a written warning. If the legal conditions are met, the employer may also terminate the employment agreement.

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.

In general, investigation materials, including findings, that includes personal data should only be processed by the personnel of the organisation who are responsible for internal investigations. However, it may in some situations be required by applicable legislation that findings are disclosed to competent authorities for the performance of their duties, such as conducting investigations in connection with malpractice and violations of the law.

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).

Please see question 7. The outcome of the investigation involving personal data may be retained only for as long as is necessary considering the purposes of the processing. In general, the retention of investigation-related data may be necessary while the investigation is still ongoing and even then the requirements of data minimization and accuracy should be considered. The data concerning the outcome of an investigation should be registered to the employee's record merely to the extent necessary in light of the employment relationship or potential disciplinary measures. In this respect, the applicable retention time depends on labour law-related rights and limitations, considering eg, the applicable periods for filing a suit.

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.

There are no regulations regarding the actual investigation process. Therefore, the employer cannot be accused of procedural errors as such. However, once the matter has been adequately investigated, the employer must decide whether or not misconduct has taken place. If the employer considers that misconduct has taken place, the employer must take adequate measures for remedying the situation. Failure to adequately conduct the investigation could result in criminal sanctions being imposed on the employer as an organisation or the employer’s representative, or damages.

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.
