Workplace Investigations

The workplace investigation can be exercised by an internal (ad hoc) investigation department of the company itself, for example under the direction of the internal audit department or compliance department. This is possible if there is sufficient manpower with the necessary independence, knowledge and experience. Case law, however, shows that courts tend to be more critical of internal investigations than external investigations. For more complex and sensitive investigations, a forensic accountant or lawyer is often involved. The advantage of involving a lawyer is that the investigation and its outcome are covered by privilege. This guarantees the confidentiality of the investigation, also regarding supervisors and investigating authorities. Yet, at the same time, there is increasing debate about the role of lawyers as investigators, given their inherent bias to work in the interests of their client (the employer).

The investigation starts with a plan of approach that must be signed by the contractor. This plan of approach outlines the legal framework of the investigation, such as the scope, the means to be used, how it will deal with data, the use of experts, how the interviews will be conducted, the way of reporting and confidentiality. Furthermore, there must be a protocol for how the investigator conducts the investigation and that applies to all parties involved.

Gathering information can be done in various ways. For example:

• An inventory can be made of the household effects of a company. In the event of theft, an inventory can be an appropriate means of establishing exactly what has been stolen.
• An investigation of the books: this is an investigation of all documents of the company. These are not private documents of employees, but documents of the company itself. For an investigator, an interview can be a good way to gather more information, for example by interviewing witnesses. In practice, there are almost always several interviews with the suspects, the employer and other people involved.
• Open source research, which often involves researching a person's social media, or public documents relevant to the research. In principle, “open sources” refers to all public documents in the world; nowadays, many public documents are digitised.
• A workplace search, which includes everything present in the workplace: diaries, computer files, e-mails, letters, and even the contents of a wastebasket.
• A digital data investigation: this is a frequently used tool in fraud investigations. Most communication and documents are digital nowadays. It is, therefore, very likely that evidence can be found in digital data. Each of these means of investigation must respect the principles of an internal investigation and comply with the GDPR principles .

Having been informed of an alleged infraction committed by an employee, the employer must prepare a detailed written accusation and notify the employee.

Moreover, if the alleged infraction constitutes gross misconduct and the employer is considering dismissal, a formal statement of the employer’s intention to dismiss the employee should accompany the accusation. If this is not expressly done, the employer will be unable to dismiss the employee and may only apply one of the conservatory sanctions. A copy of these documents must be sent to the works council, if any, and, should the employee be a union member, to the respective trade union.

Notwithstanding this, if before preparing the accusation the employer needs to further investigate the facts and circumstances, it may open a preliminary investigation aimed at collecting all the facts and circumstances and conclude if there are grounds to bring an accusation against the employee.

The preliminary investigation must start within 30 days of the employer becoming aware of the facts, be diligently carried out (but with no maximum period laid down by law) and concluded within 30 days of the last investigatory act. Furthermore, the preliminary investigation will suspend the relevant statutory deadlines and statutes of limitations (ie, 60 days from the date of acknowledgment, by the employer or a supervisor with disciplinary power, of the facts to enforce disciplinary action against the employee and one year from when the facts occurred, regardless of the employer’s acknowledgment, unless the infraction also constitutes a criminal offence, in which case the longer statutes of limitation established in criminal law will apply).

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 former Act on the House for Whistleblowers already provided for several preconditions that a whistleblowing procedure must meet. For example, internal reporting lines must be laid down, as well as how the internal report is handled, and an obligation of confidentiality and the opportunity to consult an advisor in confidence must be applied. Employers are obliged to share the whistleblowing policy with employees, including information about the employee's legal protection. The employee who reports a suspicion of wrongdoing in good faith may not be disadvantaged in their legal position because of the report (section17e/ea Act House of Whistleblowers).

The starting point is that an employee must first report internally, unless this cannot reasonably be expected. If the employee does not report internally first, the House for Whistleblowers does not initiate an investigation. The House for Whistleblowers was established on 1 July 2016 and has two main tasks: advising employees on the steps to take and conducting an investigation in response to a report.

The Act on the Protection of Whistleblowers, which entered into force in 2023, introduced several changes, of which the most relevant are:

• Abolition of mandatory internal reporting: the obligation to report internally first is abolished. Direct external reporting is allowed, such as to the House for Whistleblowers or another competent authority. When reporting externally, the reporter retains his protection. However, reporting internally first remains preferable and will be encouraged by the employer as much as possible.
• Expansion of prohibition on detriment: the prohibition on detriment already included prejudicing the legal position of the reporter, such as suspension, dismissal, demotion, withholding of promotion, reduction of salary or change of work location. It now also includes all forms of disadvantage, such as being blacklisted, refusing to give a reference, bullying, intimidation and exclusion. 
• Stricter time limit requirements for internal reporting: the reporter must receive an acknowledgement of receipt of the report within seven days and the reporter must receive information from the employer on the assessment of their report within a reasonable period, not exceeding three months.

• Extension of the circle of protected persons: not just employees, but third parties who are in a working relationship with the employer are now also protected, such as freelancers, interns, volunteers, suppliers, shareholders, job applicants and involved family members and colleagues.

The treatment of whistleblowers and their reports is laid down in various specific laws in Portugal.

Law 93/2021

Under Law 93/2021, a whistleblower of work-related offences must not be retaliated against. Furthermore, imposing disciplinary penalties on the whistleblower within two years after their disclosure is presumed to be abusive. The whistleblower is entitled to judicial protection and may benefit from the witness protection programme within criminal proceedings. Additionally, reports will be recorded for five years and, where applicable, personal data that is not relevant for the handling of a specific report will not be collected or, if accidentally collected, will be deleted immediately.

Corruption and Financial Crime Law (Law 19/2008)

Under Law 19/2008, a whistleblower must not be hampered. Furthermore, the imposition of disciplinary penalties on a whistleblower within one year following the communication of the infraction is presumed to be unfair.

Additionally, whistleblowers are entitled to:

• anonymity until the pressing of charges;
• be transferred following the pressing of charges; and
• benefit from the witness protection programme within criminal proceedings (remaining anonymous upon the verification of specific circumstances).

Money Laundering and Terrorism Financing Law (Law 83/2017)

Law 83/2017, which sets forth the legal framework to prevent, detect and effectively combat money laundering and terrorism financing, applies to financial entities and legal or natural persons acting in the exercise of their professional activities (eg, auditors and lawyers)(collectively, obliged entities).

According to article 20 of Law 83/2017, individuals who learn of any breach through their professional duties must report those breaches to the company's supervisory or management bodies. As a result, the obliged entities must refrain from threatening or taking hostile action against the whistleblower and, in particular, unfair treatment within the workplace. Specifically, the report cannot be used as grounds for disciplinary, civil or criminal action against the whistleblower (unless the communication is deliberately and clearly unjustified).

Legal Framework of Credit Institutions and Financial Companies (RGICSF)

Credit institutions must implement internal-reporting mechanisms that must guarantee the confidentiality of the information received and the protection of the personal data of the persons reporting the breaches and the persons charged. Under article 116-AA of RGICSF, persons who, while working in a credit institution, become aware of:

• any serious irregularities in the management, accounting procedures or internal control of the credit institution; or
• evidence of a breach of the duties set out in the RGICSF that may cause any financial imbalance, must communicate those circumstances to the company's supervisory body.

These communications cannot, per se, be used as grounds for disciplinary, criminal or civil liability actions brought by the credit institution against the whistleblower.

Moreover, article 116-AB of the RGICSF establishes that any person aware of compelling evidence of a breach of statutory duties may report it to the Bank of Portugal. Such communications cannot, per se, be used as grounds for disciplinary, criminal or civil liability actions brought by the credit institution against the whistleblower, unless the report is clearly unfounded.

The Bank of Portugal must ensure adequate protection of the person who has reported the breach and the person accused of breaching the applicable duties. It must also guarantee the confidentiality of the persons who have reported breaches at any given time.

Portuguese Securities Code (CVM)

Article 382 of the CVM states that financial intermediaries subject to the supervision of the Portuguese Securities Market Commission (CMVM), judicial authorities, police authorities, or respective employees must immediately inform the CMVM if they become aware of facts that qualify as crimes against the securities market or the market of other financial instruments, due to their performance, activity, or position.

Additionally, according to article 368-A of the CVM, any person aware of facts, evidence, or information regarding administrative offences under the CVM or its supplementary regulations may report them to the CMVM either anonymously or with the whistleblower's identity. The disclosure of the whistleblower's identity, as well as that of their employer, is optional. If the report identifies the whistleblower, their identity cannot be disclosed unless specifically authorised by the whistleblower, by an express provision of law or by the determination of a court.

Such communications may not be used as grounds for disciplinary, criminal, or civil liability action brought against the whistleblower, and they may not be used to demote the employee.

According to article 368-E of the CVM, the CMVM must cooperate with other authorities within the scope of administrative or judicial proceedings to protect employees against employer discrimination, retaliation or any other form of unfair treatment by the employer that may be linked to the communication to the CMVM. The whistleblower may be entitled to benefit from the witness-protection programme if an individual is charged in criminal or administrative proceedings because of their communication to the CMVM.

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.
