I believe there were settlements with the Justice Department, there's also a pending class action lawsuit. The class is all of the employees of the relevant companies during the relevant time period. (I.e. Apple, Intel, Google, Intuit, Pixar, Lucasfilm and Adobe technical employees from 2005 through 2009.)

Unfortunately, the US class action system is somewhat corrupt and in many cases the suing attorneys get the lion's share of the money, while the class members get injunctive relief, a coupon, or a nominal payment. Or sometimes they get nothing at all, and a charity gets the money (this is called a cy pres award).

Bradley laid it out well, but I would go even farther. This million employees had significant wage suppression effects for the _entire_ market, not just the employees that were working at the firms in question.
