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.

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.

Employees under investigation frequently raise grievances during investigation procedures that are dealt with on a case-by-case basis. The grievances raised by the employee under investigation are examined by the employees responsible for the investigation. They may either pause the relevant proceedings and review the grievance, especially if the claims of the employee under investigation are linked to a breach of his or her data or hearing rights, or they may continue the investigation.

It is not unusual for an employee under investigation to raise a grievance during the investigation. This grievance may be on the same subject matter as the complaint being investigated or may disclose new facts outside the scope of the matter being investigated.

Where the issue discloses new facts, the employer is required to investigate those facts without suspending the investigation. However, where the grievance relates to the same subject matter as the complaint being investigated, the employer may either suspend the investigation to allow the investigation to recognise the grievance and the complaint against the employer or proceed with the investigation while noting that the matter disclosed is being or will be investigated.

In the context of private internal investigations, grievances initially raised by the employee do not usually have an impact on the investigation.

However, if the employer terminates the employment contract due to a justified legal complaint raised by an employee, a court might consider the termination to be abusive and award the employee compensation in an amount to be determined by the court but not exceeding six months’ pay for the employee (article 336 paragraph 1 (lit. b) and article 337c paragraph 3, Swiss Code of Obligations). Furthermore, a termination by the employer may be challenged if it takes place without good cause following a complaint of discrimination by the employee to a superior or the initiation of proceedings before a conciliation board or a court by the employee (article 10, Federal Act on Gender Equality).
