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

The Czech Republic updated its whistleblower laws in June 2023 to transpose the EU Whistleblower Protection Directive’s requirements into national law. The amendments define whistleblower protections for anyone reporting violations of EU law or Czech criminal or civil offenses where the maximum penalty is at least 100,000 Czech koruna.
The 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 the Czech Ministry of Justice, 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:
The Czech Whistleblower Protection Act, known formally as Law No. 171/2023, was enacted in June 2023. It covers all organizations with at least 50 employees. Organizations with 250 or more employees were required to establish whistleblower protection programs by 1 Aug. 2023; smaller organizations were required to do so by 15 Dec. 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:

Whistleblowers are allowed to submit reports in writing, verbally, or in person. Contrary to most other whistleblower protection laws in the EU, the Czech law does not require companies to address anonymous reports, although they can always do so if they choose. A report must contain the whistleblower’s name for whistleblower protections to apply, and for the company to act upon it.

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.

Companies that fail to implement the required whistleblower program, or that ignore whistleblower reports and allow retaliation to occur, can be subject to fines as high as 1 million Czech koruna (roughly equivalent to €42,000).
