Give the money to the lawyers, burn it in the street, line it with birdcages, give it to a Colombian drug lord - it's money out of the hands of the entity that screwed over their employees, customers, etc, in the absence of any other action.
If all you want from the case is to punish the conspirators (presumably to discourage them from doing it again) then it would be a good ideat to hit them for at least what they got from screwing the employees. Which, apparently, was something like an order of magnitude larger. $324 million is, like the drug lords put it, just the cost of doing business.
If, on the other hand, there is some remote notion of compensating the people who actually got screwed, a settlement that got them, like, some money might be better. And as other commenters have pointed out, hiring your own lawyer to play Don Quixote against multiple giant corporations is not a winning proposition.
And "Junior" is so cute. I'll have to show that to the grandkids.
