Workplace Investigations

In Greece, workplace investigations are not heavily regulated.

However, internal disciplinary procedures are governed by certain general principles, while there is also legislation regulating certain aspects of investigations opened in the context of whistleblowing procedures or concerning complaints for workplace violence or harassment. These include Law 4990/2022, which transposed EU Directive 2019/1937 into Greek Law; and Law 4808/2021, which ratified the ILO’s Violence and Harassment Convention, 2019 (No190) and introduced relevant provisions.

As far as disciplinary procedures in private-sector companies are concerned, employers that must have internal labour regulations in place (ie, those with more than 70 employees) or opt to adopt them voluntarily, can regulate the procedures themselves.  

In the public sector, internal investigations are governed by disciplinary provisions included in the civil servant code.

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.

According to express provisions of L.4990/2020, in principle personal data and any other information that may lead directly or indirectly to the identification of the complainant must not be disclosed to anyone other than the investigating individuals unless the complainant gives consent[4] and that is why pseudonyms should be used. The witnesses and third persons that aid the complainant are deemed as “mediators” by the Law and their contribution to the procedure should be confidential[5].

L.4808/2021 does not indicate when such disclosures are permitted; however, it is obvious that this is a matter of cost-benefit analysis where the public interest and the fundamental rights of the involved persons should be considered in a balanced way to ensure the best results. From a data protection perspective, it could be argued that the person under investigation’s right to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of these persons.

An employee served a notice of accusation is entitled to assess all information that was gathered within the scope of the investigation and disciplinary procedure (notably the identity of the complainant, witnesses heard, other sources of information, etc), otherwise his right of defence may be jeopardised.

Where a preliminary investigation does not lead to an accusation against the employee, no disclosure has to be made by the employer.

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]
