Workplace Investigations

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]

After the employee is notified of the accusation, the employer may decide on a preventive suspension of the employee if the employee’s presence on company premises is deemed problematic. In this case, the employee’s salary will continue to be paid.

As per article 330(5) of the Portuguese Labour Code, a preventive suspension may also be determined during the 30 days before the accusation is made, provided that the employer, in writing, justifies why is necessary (eg, for interfering with the inquiry) and why the accusation cannot be served at that moment.

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.

If, before taking disciplinary action, the employer decides to open a preliminary investigation phase, the employee does not have to be informed.

Only when the preliminary investigation leads to a formal accusation will the employee be entitled to know that enquiries were carried out and the source of the facts (eg, witnesses, documents).

However, if an employer does not need to open a formal preliminary investigation phase, it only has to serve the accusation notice to the employee.

As a rule, employees will only know that they are being investigated if they are suspended or when they are notified of the accusation.

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).
