In November 2019 the EU Whistleblower Directive came into force. Whistleblowing has been described as a human right and a freedom fundamental to democracy. But it is not always straightforward to understand concrete cases of reporting wrongdoing in terms of abstract political philosophy. This paper uses a discussion between Berlin and Skinner about what negative freedom is, as a theoretical framework to understand the struggles of a campaigning platform of trade unions and civil society organizations, in the coming about of the EU Whistleblower Directive. The paper is empirically based on a document analysis of two Resolutions in the European Parliament, the European Commission’s proposal text, the approved text in the European Parliament, and messages on the listserv of the campaigning platform between February 2017 and April 2019. The paper provides insights on how whistleblowing freedom relates to public interest and autonomy.
