Whistleblower law in Greece #
Greece implemented Directive (EU) 2019/1937 through Law 4990/2022. The Greek framework combines the standard private-sector threshold with a named internal reporting officer and an external channel operated by the National Transparency Authority.
Applicable law #
Who must establish an internal channel #
Private-sector entities with more than 50 workers must establish an internal channel and appoint a reporting officer. Public bodies are also in scope under the Greek framework.
External reporting authority #
The official external channel is the National Transparency Authority , which receives reports under Law 4990/2022 and publishes implementation material for obliged entities.
Data protection authority #
For complaints about unlawful handling of personal data or confidentiality issues, the relevant authority is the Hellenic Data Protection Authority .
Key compliance points #
- Greek implementation material expects written, oral and meeting-based intake options.
- The reporting officer is a named compliance role, not just a generic mailbox.
- Official Greek guidance states that private entities in the 50-249 band may use shared reporting officers for intake.
