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.

If the employer decides on an internal investigation to assess potential wrongful actions carried out within the company, employees must cooperate. However, employees are entitled to the privilege against self-incrimination established in the Portuguese Criminal Code, according to which individuals are not obliged to self-report.
An employee's refusal to cooperate with an internal investigation may be regarded as a breach of conduct by the employer and, ultimately, may lead to disciplinary sanctions.
Employees who act as witnesses in cases of harassment cannot be sanctioned unless they acted with wilful misconduct, and any sanction applied to an employee who acted as a witness in a harassment procedure will be presumed to be abusive.

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.
The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

Normally, the work rules prescribe requirements for cooperation with investigations. An employer may instruct co-workers to give statements as witnesses as this would be a fair and legitimate order of the employer, because investigations are conducted to maintain a good working environment.
Witness protection measures in a workplace can vary as no minimum standard has been set and they are generally subject to work rules and regulations. However, some legislation, which may not relate to a workplace investigation conducted by an employer, also protects the witnesses who are helping authorities investigate violations under the relevant acts. For example, the Labor Relation Act B.E. 2518 (1975) prohibits an employer from terminating an employee or conducting any action that may result in the employee being unable to work because of filing a complaint or being a witness for the authorities, or providing information on issues related to labour protection laws to the authorities.
The employer may have a policy of non-retaliation for the protection of witnesses who have given statements and evidence for a workplace investigation.

The employer is allowed to search an employee’s possessions or files, provided that they are work instruments or of a professional nature.
When performing these searches, employers should consider the specific provisions of the Data Protection Regulations as well as Resolution No. 1638/2013 of the Portuguese Data Protection Authority (CNPD), which contains rules on monitoring phone calls, e-mail and internet usage by employees. The CNPD understands that for the employer to access the employees’ professional data (e-mails, documents and other information stored on electronic devices), the latter should be present during the monitoring, to identify any information of a personal nature that should not be accessed by the employer (the employer must comply with these directions and should not access that email). In addition, review of the data should respect specific protocols to avoid potential access to personal data (eg, review of subject, recipients, data flow and type of files attached).
Body searches or the seizure of personal belongings or documents belonging to the employee are not permitted within the scope of a disciplinary procedure.

The basic rule is that the employer may not search private data during internal investigations.
If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

Electronic information created during employment would generally be owned by the employer and would be the employer’s assets. If an employee is given a computer or laptop to use for work, the employer has the right to log into that device and take any data that is stored therein, provided that the data does not contain sensitive information of that employee and PDPA requirements are met.
To avoid any potential issues regarding physical data such as documents on the employee’s desk, it is advisable to search those areas with the subject employee to show good faith. In practice, the employee normally agrees to search those areas with the employer, or allows the employer to search alone.

There are no specific rules in the Portuguese Labour Code on this matter.
However, article 332 of the PLC states that the employer should keep an updated record of disciplinary sanctions, so the competent authorities can easily verify compliance with applicable provisions. Accordingly, it is advisable to maintain a record of disciplinary sanctions during the entire employment relationship.
Also, please note that some collective bargaining agreements state that the disciplinary register must be deleted from the employee’s record periodically.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.
From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]

There is no period required by law for keeping the outcome of the investigation on the employee’s record. However, if termination of employment is the outcome of the investigation, an employer should keep details of the investigation for at least 10 years, in line with the prescribed period for an employee to file an unfair dismissal claim against an employer. An employer may use the details of an investigation to defend such a claim. For other disciplinary action, the retention of investigation details on the employee’s record is at the employer’s discretion.
