Final answer:
The three main topics in the ethics of whistle-blowing according to Duska are duty of loyalty, public interest, and harm. These topics revolve around the ethical balance between an employee's loyalty to their employer and their obligations to prevent harm and uphold the public interest.
Step-by-step explanation:
The three main topics in the ethics of whistle-blowing, as discussed by Ronald Duska, are b) Duty of loyalty, public interest, and harm. Duska's view on whistle-blowing revolves around the concept that the primary obligation of the employee is not to the employer, but to the ethical duty of not causing harm and acting within the public's interest. Whistle-blowing, therefore, becomes a morally permissible act, especially when it is to prevent harm or wrongdoing that affects the public at large. This perspective challenges traditional notions of corporate loyalty, which suggest that an employee's loyalty to their employer should prevent them from disclosing sensitive information that could damage the employer.
Whistle-blowing involves complex ethical considerations that often need to balance loyalty to an employer, potential harm to the public, and the importance of transparency and accountability, especially in scenarios where public welfare and safety are at stake. In light of this, Duska argues that the obligation to prevent harm and protect public interest outweighs the supposed duty of loyalty to a business entity that could be engaged in unethical practices.
