# Whistleblower law in Slovakia

Slovakia implemented Directive (EU) 2019/1937 by amending **Act No. 54/2019 Coll. on the Protection of Whistleblowers of Anti-Social Activities**. Slovakia stands out because it has a visible and specialised **Whistleblower Protection Office** rather than a low-profile distributed model.

## Applicable law

- [Act No. 54/2019 Coll. — official text on Slov-Lex](https://www.slov-lex.sk/pravne-predpisy/SK/ZZ/2019/54/)
- [Whistleblower Protection Office](https://www.oznamovatelia.sk/en/)

## Who must establish an internal channel

Employers with **at least 50 workers** must establish an internal reporting channel under the Slovak whistleblower framework.

## External reporting authority

The specialised external authority is the [Whistleblower Protection Office](https://www.oznamovatelia.sk/en/), 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](https://www.dataprotection.gov.sk/en/rights-data-subjects/proceedings-on-protection-personal-data/).

## 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.
