you may settle, but you will expose no one. Any settlement deal will result in a NDA, which means you can tell no one about your settlement. Exxon gets sued all the time, and they settle frequently. Everyone settles because nobody wants to really go to battle with Exxon in a trial. It's expensive and you may lose. They have the upper hand.. If they come to you and offer you $100k for your troubles, what are you going to do? Go to trial, possibly spend $500k, and lose?
It's and insidious cycle, and exxon knows how to play the game. They know the probabilities that someone will sue, and they work that into their overall plan. They still come out ahead, they still get to treat people however they want because they never get bad press because of the NDAs and as a result one cannot show a "continuous pattern of abuse, across the corporation." They are the epitome of the evil, soulless corporation.
