Workplace Investigations

According to article 356(1) of the Portuguese Labour Code, the employer can appoint an instructor, who shall be responsible for the probationary proceedings. Usually, workplace investigations are conducted by external advisors (eg, lawyers), appointed by the employer.

However, regarding disciplinary powers, there is a legal limitation in article 98 of the Portuguese Labour Code. As such, only the employer (or the immediate superior of the concerned employee, if the employer has delegated its powers, as per article 329(4) of the Portuguese Labour Code) has disciplinary powers.

As set out in question 1, workplace investigations must be proportional and companies must use the least intrusive means to affect employees’ rights. This translates into the following principles on who conducts the investigation:

• the enquiry must involve a minimal number of employees;
• only those employees with competencies on the investigated matters should be involved (normally human resources or compliance); and
• employees conducting the investigation must be qualified and have the power and seniority to do so proficiently (although a formal qualification is not required).

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

The investigation findings must be disclosed to the employee when an accusation is brought against him or her and to the works council (if any) or trade union, if the employee is a member.

Regulators or police authorities may also notify the employer if any investigations were brought against a particular employee (as regards regulators, this could occur within the scope of fit and proper procedures), in which case the employer must cooperate and disclose any investigation findings.

Companies may only disclose the outcome of an investigation to employees or officers of the company who are empowered to adopt the measures that are necessary because of the investigation’s results (see question 4).

This disclosure obligation does not extend to authorities: while there is a general obligation to report criminal or administrative offences to the competent authorities, this obligation must be read in line with the companies’ right not to self-report themselves. What a company must not do is cover up, aid or otherwise become an accessory to the offence.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]
