If you agree to a settlement, you can get plenty of moolah, but the company won't be found guilty of wrongdoing. So if it happens again, they will just offer another settlement. It's a sort of admission of guilt, but it's not a conviction. All the way for the jugular means to make them truly pay by finding them guilty of libel in a court of law.

I knew a guy who worked for a company here in Japan. He took them to court because they were cheating him out of benefits by "nickle and diming" his work hours by expecting everyone to essentially work on their break time. If you work a certain amount of hours per day, you are entitled to benefits, etc. But even though he was working those hours, the company's stupid policies were reducing the amount of time per day for employees, even though they were working the time. He agreed to take a settlement, which mean that the company could continue to do the same to everyone else. If he had pushed the trial further and the company was found guilty, then he could have effected change for all employees. It wasn't until years later that somebody else took them to court, did not accept a settlement, "went for the jugular," and then the company was forced to provide benefits for all of their employees
