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 are essentially two phases in a workplace investigation: the fact-finding phase and the administrative proceeding.
The fact-finding phase of workplace investigations is usually governed by the internal policies of the employer, save for investigations relating to gender-based sexual harassment in the workplace. Republic Act No. 11313, otherwise known as the Safe Spaces Act, sets the parameters for these kinds of investigations.
Philippine case law recognises the right of an employer to conduct investigations for other acts of misconduct in the workplace in the exercise of its management prerogative. The Supreme Court has held that it is an employer’s right to investigate acts of wrongdoing by employees, and employees involved in such investigations cannot simply claim that employers are out to get them.
After the fact-finding aspect of the investigation, if the employer decides it has sufficient grounds to proceed to full-blown administrative proceedings, it needs to comply with the due process requirements outlined under the Philippine Labor Code. These requirements are:
- a first notice, or notice to explain, informing the employee of the charges against him or her;
- an opportunity for the employee to be heard; and
- a final notice on the outcome of the administrative action.

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.

Workplace investigations are normally commenced either through a complaint filed by other employees in the workplace or by HR or other representatives of management.
Under the Safe Spaces Act, employers are required to commence an investigation and decide on complaints regarding gender-based sexual harassment, within ten days of the complaint being brought to their attention. For other workplace misconduct, management is given wide discretion regarding the means and method by which the workplace investigation may be carried out.

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.

A preventive suspension pending investigation is allowed under the law, provided that the continued employment of the subject of the investigation poses a serious and imminent threat to the life or property of the employer or other employees. Additionally, the period of preventive suspension pending investigation should not last longer than 30 days. However, should the employer wish to extend this period, the employer must pay the employee’s wages and other benefits. The employee is under no obligation to reimburse the amount paid to them during the extension if the employer should, later on, decide to dismiss the employee after the completion of the process.
In practice, the notice of preventive suspension is issued simultaneously with the first notice or the notice to explain after the employer has conducted its fact-finding investigation and has reason to believe that the employee must be held accountable for his or her actions.
Since placing an employee under preventive suspension requires the existence of a serious and imminent threat to the life or property of the employer or other employees, some employers opt to place the employee or employees involved on agreed paid leave. This will allow the employer to conduct an unhampered workplace investigation while the investigated employee is still able to receive his or her full salary during this period. The exact period of paid leave may be agreed upon by the employer and the employee, but ideally it should not last for more than thirty days.

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.

Under the Safe Spaces Act, an employer should create an independent internal mechanism or a committee on decorum and investigation to investigate and address complaints of gender-based sexual harassment, which should:
- adequately represent the management, the employees from the supervisory rank, the rank-and-file employees, and the union, if any;
- designate a woman as its head and no less than half of its members should be women;
- be composed of members who are impartial and not connected or related to the alleged perpetrator;
- investigate and decide on the complaints within 10 days or less upon receipt thereof;
- observe due process;
- protect the complainant from retaliation; and
- guarantee confidentiality to the greatest extent possible.
For other types of offences, it is the prerogative of management as to who will conduct the investigation and how it will be conducted, provided the proceedings remain impartial.

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 generally no legal remedy for an employee to stop a workplace investigation as it is the prerogative of management to conduct it. Nevertheless, if the employee alleges violation of any specific law or contractual provision in the conduct of the investigation, the employee may be able to seek judicial relief for violation of the law or contract, and ask for interim relief.

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.

Neither the employer nor the employee subject of the investigation can compel co-workers to act as a witness. There is no specific law for whistleblowers or employees who act as witnesses during an investigation. Nevertheless, the employer can have its own whistleblower policy.

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.

Subject to the employees’ reasonable expectation of privacy, gathering physical evidence within the premises of the workplace and through company-issued property has been upheld to be legally permissible in pursuit of the employer’s right to conduct work-related investigations. The search, however, should be limited to the alleged acts complained of and must not be used as a fishing expedition to find incriminating information about the erring 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.

Since the right to investigate ultimately belongs to the employer, it may impose strict confidentiality obligations upon the individuals involved, not only to ensure unhampered investigation proceedings but also and more importantly for the protection of the company and employees involved.

During the fact-finding stage of the investigation, the employees under investigation are not generally entitled to information concerning the conduct of the investigation. It is the prerogative of management to involve the employee under investigation during the fact-finding stage. When, however, the employer determines that an administrative disciplinary process must proceed, the employee’s right to due process attaches. As such, due process includes the right to be informed of the grounds relied upon by the employer and the opportunity to be heard. The first notice or notice to explain should specifically inform the employee of the charge against him or her.

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.

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.

A labour union has no legal right to be involved in the investigation.

Since the conduct of an investigation is different from the administrative disciplinary process, management is given wide latitude for the exercise of the same.
After the employer determines that there are sufficient grounds to support the conduct of a formal administrative process, employees that are the subject of an administrative hearing should be allowed to present evidence to support his or her statements. Further, the employee may also provide affidavits of his or her co-employees consistent with his or her testimony.

If an employee under investigation raises a grievance during an ongoing investigation, the employer must ensure that the employee under investigation is treated reasonably and fairly. Thus, the employer must also give attention to the complaint made by the employee and determine if there are reasonable grounds for the concern of the employee. If the employer determines the validity of the grievance raised, the employer may conduct a separate investigation for it.

Since neither consent nor the presence of the employee is material to the conduct of the investigation, his or her absence would not, in practice, imperil the conduct of the investigation.
As previously discussed, because the employer exercises a wide latitude of discretion in conducting workplace investigations, the employer may choose to proceed with the investigation despite the absence of the employee being investigated. Since the proceeding is only in the investigation phase, the statutory right of the employee to be heard is not violated, even if the investigation takes place without his or her participation.

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.
Philippines

It is within the employer’s discretion to pursue the investigation even if a parallel criminal or regulatory investigation is taking place. As such, different investigations may proceed independently of each other. However, if the workplace investigation would interfere with or hinder the criminal or regulatory investigation, the workplace investigation should defer to the investigation being conducted by the people in authority. Since the nature of a workplace investigation is highly confidential, the police or regulations cannot compel any evidence from the employer without a court order.

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.

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).

An employer may be liable for illegal termination if a dismissal is made based on wrong information collected during the investigation. Thus, the data and information gathered during the investigation stage must be correct and accurate. Further, investigations should be conducted in a manner that is fair and reasonable to the employee under investigation. Otherwise, the employee may treat the investigation as harassment on the part of the employer, which may subject the employer to a potential lawsuit.
