Workplace Investigations

Austrian law does not impose an obligation on employers to conduct internal investigations and they do not have to follow a specific legal pattern when doing so. However, an obligation to conduct internal investigations may arise out of certain provisions of criminal, company or even labour law – in particular, an indirect obligation arising from an employer's duty of care, which requires them to act against employee mistreatment, such as bullying.

If such internal investigations are initiated, compliance with labour law and data protection regulations is mandatory. According to section 16 of the Austrian Civil Code (ABGB), the employer must also protect the personal rights of the individual. It is important to emphasise that a company's internal investigation is a private measure and differs from official 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.

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.

Private investigations differ from criminal or regulatory investigations. Nevertheless, even for internal investigations, it is advisable to collect evidence in a way that can be admitted in court, as it may have to be presented to the authorities during the investigation process. Generally, any evidence obtained in the course of an internal investigation may be admitted in subsequent administrative or judicial proceedings.

If the evidence is not voluntarily surrendered, seizure or confiscation is possible. Since official proceedings are often lengthy, suspension is not always recommended.

Incidents of violence and harassment may be dealt with by certain independent authorities, such as the Labour Inspectorate Body and the Greek Ombudsman. The former is competent to impose sanctions on the employer if there is a breach of the general prohibition of violence and harassment at the workplace and the obligation of employers regarding the prevention of such incidents and the obligation to adopt policies within the business. The Greek Ombudsman is competent to deal with disputes when there is violence or harassment in the workplace coupled with discrimination due to, for example, gender, age, disability, sexual orientation, religious beliefs, or gender identity. Moreover, the applicable legal framework[13] stipulates that victims of violence and harassment are entitled to lodge a report before the Labour Inspectorate Body and the Greek Ombudsman. This is in addition to the judicial protection he or she may seek and the internal investigation procedure to which he or she may have recourse, without specifying whether internal proceedings may be suspended before the regulatory bodies decide on the matter.

On the other hand, the National Transparency Authority and in certain cases the Hellenic Competition Commission are external reporting channels for employees reporting breaches of Union law. In such cases, L.4990/2022 (article 11 paragraph 5) stipulates that the investigation before the National Transparency Authority is not suspended if reporting procedures before other regulatory authorities have been initiated.

Moreover, criminal investigations can run in parallel with internal probes.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
