Workplace Investigations

The Portuguese Labour Code does not specifically provide for any confidentiality obligations concerning disciplinary procedures. On the contrary, it states that the employee should have access to any information included in the disciplinary procedure. Otherwise, the employee’s defence rights could be jeopardised, which would make the disciplinary procedure (and possible disciplinary sanctions) null and void.

As for the witnesses, even though there is no specific provision on confidentiality, employees are generally bound by a duty of loyalty vis-a-vis the employer, which includes not disclosing information that should be kept reserved,

However, in the cases of whistleblowing, it is mandatory to ensure the confidentiality of the complainant, as per question 9.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

Once the preliminary investigation ends, the employer must decide whether or not, in its view, there are grounds to bring an accusation against the employee and enforce disciplinary action or if it should be dismissed due to a lack of evidence.

When the employer decides to enforce disciplinary action, the following sanctions may be applied:

• verbal warning;
• written warning;
• financial penalty;
• loss of holiday;
• suspension with loss of pay and length of service;
• dismissal with cause and without compensation.

The first five penalties are usually called conservatory sanctions, enabling the continuity of the employment relationship, as opposed to dismissal, which is deemed a measure of last resort.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.
