A whistleblower is an individual who reports unethical or illegal activities within an organization. This can include exposing fraud, corruption, or safety violations. Whistleblowers often work in various sectors, including government, healthcare, and corporate environments, and their actions can lead to significant changes in policies or practices. Whistleblowers may face risks, such as retaliation or job loss, for speaking out. To protect them, many countries have laws and regulations, like the Whistleblower Protection Act, that provide safeguards and encourage reporting. Their contributions are vital for promoting transparency and accountability in organizations.
