On Wednesday, US District Judge Lucy Koh granted preliminary approval for a settlement between four top tech companies—Apple, Google, Adobe, and Intel—and their former employees. The employees launched a class action suit against the companies after the Justice Department sued the top tech firms for anti-competitive labor practices in 2010.

The Justice Department had accused Apple, Google, and other top tech firms of agreeing not to approach each others’ engineers with better employment offers. The employees estimated that they collectively lost out on $3 billion in wages because competing companies would not give them better offers.

Lucasfilm, Pixar, and Intuit were also part of the original suit, but employees of those companies settled for $20 million early on in the suit.
