And realistically, if you sue a previous employer, even for very good protected reasons, good luck on ever getting hired again. My friend's brother was fired for complaining about constant sexual harassment from his (female) boss. He ended up winning the lawsuit, as even her e-mails were clearly harassing him and several witnesses confirmed his version of accounts.
He got a $50,000 payout on top of money they were holding for a total of about $75,000. His lawyers took their standard third so he was back to about $50,000. After that, it took him 2 YEARS to get hired because every company saw a lawsuit against his previous employer and refused to hire him right there.
