Whistleblower law in Slovakia #

Slovakia implemented Directive (EU) 2019/1937 through Act No. 189/2023 Coll., amending Act No. 54/2019 Coll. on the Protection of Whistleblowers of Anti-Social Activities. The amendment took effect on 1 July 2023, with several provisions following on 1 September 2023. Slovakia stands out because it has a visible and specialised Whistleblower Protection Office rather than a low-profile distributed model.

Applicable law #

Who must establish an internal channel #

Employers with at least 50 workers must establish an internal reporting channel under the Slovak whistleblower framework. Entities in the financial-services and anti-money-laundering, transport-safety, and environmental sectors are in scope regardless of headcount.

External reporting authority #

The specialised external authority is the Whistleblower Protection Office , which protects whistleblowers, supervises the law’s application and provides guidance to both workers and employers.

Data protection authority #

For GDPR complaints relating to report handling, the relevant authority is the Office for Personal Data Protection of the Slovak Republic .

Key compliance points #

Slovakia has one of the more visible dedicated whistleblowing institutions in CEE, which means buyers often expect a more formal legal framing.
The Whistleblower Protection Office can intervene in retaliation-related employment measures, which gives the Slovak regime a strong protection profile.
Slovak official materials distinguish between the employer’s internal process and the office’s own protection and reporting functions, so product copy should do the same.
