  We don't have the right to tell our bosses, "I won't do that, because it's unethical".

What do you mean we don't have that right? As a human being, I always hold that right and will use it if necessary. Fuck a job - if a decision that I have the power to make/not make results in something unethical happening then I'll make sure the person telling me knows this. And if they still insist, then I walk. Just like your doctor analogy.
