Final answer:
The course of action that is NOT recommended for dealing with at least one of the four rationalizations commonly used to justify unethical behavior is to believe that if other people and other companies are doing it, you are justified in doing it too.
Step-by-step explanation:
The course of action that is NOT recommended for dealing with at least one of the four rationalizations commonly used to justify unethical behavior is B. If other people and other companies are doing it, you are justified in doing it too. This is not a recommended approach because it relies on the actions of others to justify unethical behavior, rather than considering the ethical implications and consequences of one's actions.
Instead, it is important to focus on ethical principles and long-term implications. This includes looking beyond short-term results (C), making sure wrongdoing is punished if discovered (D), and recognizing that organizational loyalty should not stand above the law and social morality (E).
