Explore the Greece Whistleblower Protection Law, including compliance requirements, scope, and how to support and protect reporting in your organization

Greece enacted a whistleblower protection law at the end of 2022 to transpose the EU Whistleblower Protection Directive’s requirements into national law. The amendments define new and expanded whistleblower protections for anyone reporting violations of EU law only – not violations of Greek national law as well.
The new legislation covers all public and private organizations with at least 50 employees, requiring them to establish mechanisms to allow for whistleblower reports and to protect whistleblowers. Employers must also appoint someone to investigate whistleblower claims, and this can be an internal manager or an external third party.
The law protects whistleblowers and those assisting them from retaliation for submitting a report. It also allows them to report their concerns externally to Greece’s National Transparency Agency; or even directly to the press if the whistleblower believes reporting via the other two channels will be ineffective.

The law adopts the minimum standards for whistleblower protection outlined in the EU Whistleblower Protection Directive. These requirements include:
Known formally as Law 4990/2022, Greece’s whistleblower protection law covers all organizations with at least 50 employees. Organizations with 250 or more employees had to establish their whistleblower programs by May 11, 2023; smaller organizations must do so by the end of 2023. Organizations with fewer than 250 employees are also allowed to establish a joint whistleblower program in coordination with other small businesses. Financial service firms need to establish an internal reporting system even if they have only one employee.

The law requires all covered businesses to

Companies are allowed to outsource the management of their hotline to a third-party service provider, although companies that do so are still responsible for responding to whistleblower complaints on the timelines outlined above.
Greece’s law does not expressly encourage anonymous reporting, but does say that if an anonymous reporter’s identity is discovered at a later point, that person is entitled to the same whistleblower protections as any other reporter.

Whistleblowers are allowed to submit reports in writing, verbally, or in person, and the company must preserve a record of every report submitted. The law also prohibits retaliation of any kind against whistleblowers: harassment, pay cuts, withholding of promotion, canceling expected employment contracts, and so forth. Whistleblowers who believe they’ve suffered retaliation are entitled to free legal advice, and can receive compensation if their retaliation claims are proven true.

Companies that fail to implement the required whistleblower program can be subject to fines ranging from €10,000 to €500,000.

Across continental Europe, organisations report 0.85 whistleblowing cases per 100 employees, and 58% of reports are submitted anonymously. In the UK, reporting rates are even lower at 0.69 cases per 100 employees, while anonymity levels are higher at 66%. Both figures sit in contrast to the global benchmark of 1.65 cases per 100 employees. What can these benchmarks tell us about the health of speak-up cultures across Europe, and what can organisations do to strengthen employee trust and reporting confidence?
