This document summarizes Mark Worth's presentation on whistleblower protection at an OECD conference in Paris. It outlines how many countries have passed whistleblower protection laws since the late 1980s and 2000s in response to scandals. However, most of these laws still lack adequate protections and enforcement mechanisms. The document then provides examples of whistleblowers in various countries who were reinstated or received compensation after facing retaliation, demonstrating that cultural attitudes can change with media exposure, public support, and adaptive training by governments. It argues a combined bottom-up and top-down strategy is needed to continue improving whistleblower laws and protections.
