Final answer:
Bob may have a claim for wrongful termination under public policy exceptions, as well as whistleblower protections, due to his refusal to engage in an illegal act that violates international laws (option 3).
Step-by-step explanation:
In the scenario presented, Bob is asked to engage in an illegal act by pouring grease into a creek, a demand which he refuses. If he is subsequently fired for his refusal, Bob may have grounds to claim wrongful termination based on public policy exceptions to at-will employment. Many jurisdictions protect employees from being terminated for reasons that violate public policy, such as refusing to break the law on behalf of their employer.
Moreover, if the act of pouring grease into the creek violates international laws, and Bob is fired for refusing to engage in that act, he may also be considered a whistleblower. Whistleblowers are protected under various laws, both at the national and international levels, when they report or refuse to participate in illegal activities. These protections can provide a legal grounds to claim wrongful termination.
Accordingly, the correct answer to the question posed by the student would be: Yes, this violates public policy and Bob could potentially sue for wrongful termination as a whistleblower.
Hence, the answer is option 3.
