There is a big upside though to a principled resignation: you do not have to look back knowing that you chickened out when you should have opposed dishonesty by your superiors.
Of course there is.And for lawyers that upside wouldn't necessarily come at a high cost.But this is a dog-eat-dog world and many people don't have skills that are in such high demand that they can easily change employers.The ability to feed one's family is a strong motivator.
