Whistle blowing refers to an employee reporting illegal or unethical behavior by their employer or supervisor to the appropriate authorities. It can be done internally by reporting within the organization or externally to outside parties. There are guidelines for when whistle blowing is appropriate, such as when harm is serious, formal channels have been exhausted, and the employee has documented evidence. Organizations should prevent the need for whistle blowing by creating a strong ethical culture, open communication channels, and independent ethics committees to investigate complaints.
