Workplace Investigations

Pursuant to article 98 of the Portuguese Labour Code, the employer has a disciplinary power over its employees during the employment period. This is enforced through the initiation of disciplinary procedures – which can include a preliminary workplace investigation as provided for in article 352(1) of the Portuguese Labour Code – and ultimately the application of sanctions laid down by law or in an applicable collective bargaining agreement.

The Portuguese Labour Code governs disciplinary procedures, which can include a preliminary workplace investigation, in two different sections. On the one hand, articles 328 to 332 establish general rules regarding the imposition of disciplinary sanctions; statutory deadlines and statutes of limitations involved; decision criteria; penalties; and disciplinary records. On the other hand, articles 351 to 358 lay down the rules applicable to dismissals with cause, which are also widely understood to be applicable concerning conservatory sanctions (i.e. those that enable the continuity of the employment relationship).

Additionally, collective bargaining agreements may provide for different disciplinary penalties, as long as the rights and guarantees of employees are not impaired.

Workplace investigations must also abide by the general rules laid down in the Portuguese Constitution, Portuguese Civil Code and Data Protection Laws (including guidelines issued by the Data Protection Agency), as regards the personal rights of the employees.

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.

In the UK, the primary employment legislation of relevance to a workplace investigation includes the Employment Rights Act 1996 (ERA 1996), the Equality Act 2010 (EA 2010), and the Employment Relations Act 1999 (ERA 1999).

Other legislation includes the retained EU law version of the General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA 2018), the Investigatory Powers Act 2016 (IPA 2016) and the Investigatory Powers (Interception by Businesses etc for Monitoring and Record-keeping Purposes) Regulations 2018 (IP Regs 2018), and the Humans Rights Act 1998 (HRA 1998).

In terms of guidance, the Advisory, Conciliation and Arbitration Service (ACAS) have produced a Code of Practice on Disciplinary and Grievance Procedures (the ACAS Code) as well as a Guide to conducting workplace investigations. The Information Commissioner’s Office (ICO) have their Employment Practices Code,  and other pieces of guidance on the data protection aspects of investigations (see question 7).

Most employers will have internal policies governing how workplace investigations should be conducted. The level of detail may vary considerably; public sector and regulated employers may be more prescriptive in their policies, which may even have contractual force. There may also be provisions of the employment contract that are relevant (particularly as regards suspension – see question 3).

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.

The employer should first identify which individuals may have protection as whistleblowers. This could be a current or former employee who raises the initial complaint, a co-worker who gives evidence as part of the investigation, or the accused employee.

In each case, consider whether a “protected disclosure” has been made (under Part IVA ERA 1996). This requires analysis of the subject matter of the disclosure, how it is made, and a reasonable belief that it is made in the public interest.

Employers must then ensure there is no detrimental treatment or dismissal of any worker on the grounds of their protected disclosure. Although the causation test for these purposes is not straightforward, as a general rule if the protected disclosure has a “material influence” on the decision to discipline or dismiss, there may be liability. Individual managers may be personally liable alongside the employer. Compensation for whistleblowing cases is uncapped, meaning businesses and individuals can face significant financial and reputational exposure.

What this means in practical terms is that the employer should promote a “speak-up” culture and, where protected disclosures are made, ensure they are handled by a team who are properly trained in how to do so.
