Ive worked for companies that have shorted me financially to the tune of high 5 figure sums. I have been passed over for promotions that were unfounded. I quit, I didnt get lawyers involved. Suing would damage my reputation on the job market. I cant endorse bad behavior, but what makes people expect that a nuclear option wont have consequences, fair or unfair?
I think what you're describing is the real problem here. If there's some sort of (informal) "old-boy's-network" that keeps people from legitimately using the law when they have been wronged, then we should support those willing to publicly start fights with that establishment.
If every woman who was sexually harrassed just quit, the workplace environment for women would still be like the '50s. Individuals have to make a stand for better treatment for all.
If 1% of guys are scumbags, and 5 days a year they really act like it, and you play that out for 10 years.. most women could be harrassed at some point or other even though 99% of guys are innocent.
