Compartmentalize. Your day job du jour is not your life, nor the meaning thereof. And you definitely need multiple other sources of self-esteem and social interaction. Have Red Lines. All-consuming work weeks, broken promises, inter-personal nastiness, lack of credit, shorted or crappy pay, ways you won't treat other people, lies you won't tell, etc. Have a Plan B. Whether BigCo crosses one of your Red Lines, or just lays you off, or your job there stops seeming "worth it for now" - do what you can to make sure you won't be SoL for lack of alternatives. (Yes, thinking about and working on a Plan B or few can be one of your positive Compartments.) Exit Gracefully. Even if you're 100% in the right, angry rants and telling tales are very unclassy. And will help convince a lot of people that you're in the wrong. Or are making shit up. Or that BigCo's HR was smart to dump a hot-tempered liability like you. Privately practice explaining your departure in understated and ever-so-blameless corporate terms. In a neutral, passive voice drone-tones. Avoid Legal Action. In serious cases, 99% of the people who say or know too much are treated as expendables. If you quit when BigCo was dumping toxic waste into the municipal water supply, and wanted you to sign off on that? Even if kinda pressed, say "I was a bit concerned that a few things had been underbid, so in the future it might become miserably difficult to maintain full regulatory compliance." No hint that you ever knew specific details, let alone of any wrongdoing. Be very aware that big-case lawyers are extremely good at tracking down expendables who know too much, getting them to say too much, then dragging them into court.
