This document discusses whistleblower protection legislation and mechanisms. It defines whistleblower protection as protecting public and private sector employees who report suspicions of corruption in good faith from retaliation. Whistleblower protection encourages reporting of misconduct and increases accountability. Legal sources of protection include anti-corruption, labor, and securities laws as well as international agreements. Effective protection mechanisms prevent retaliation, ensure confidential reporting procedures, and provide enforcement and remedies for retaliation. Challenges to protection include lack of awareness, fear of reprisals, and cultural barriers, which can be addressed through education and fostering a transparent organizational culture.
