Based on the above-mentioned dilemma regarding the whistleblower’s protection under EU and the Council of Europe law on the one hand and the data protection right of access under EU law on the other hand, the question arises under what conditions is an employer obliged in an individual case to provide the desired information to the data subject and to what extent must the employer protect the confidentiality of the whistleblower’s identity. The fact that these two rights may directly clash has already been foreseen by the legislator of the Whistleblower Protection Directive.
