You'd have to be at a pretty high level for a future employer to do a public records search on you (not to be confused with a background check), thus the compensation you would receive for a retaliatory firing would likely be in the millions (or tens of millions) of dollars as it is often based on lost income and has a punitive component. You'd likely never have to work again.

Many employers of mine have done background checks on me prior to extending an offer. And there's this hip things the kiddos are using called "Duck Duck Go".
