When labor advocates and law enforcement officials talk about wage theft, they are usually referring to situations in which low-wage service-sector employees are forced to work off the clock, paid subminimum wages, cheated out of overtime pay or denied their tips. It is a huge and underpoliced problem. It is also, it turns out, not confined to low-wage workers.

In the days ahead, a settlement is expected in the antitrust lawsuit pitting 64,613 software engineers against Google, Apple, Intel and Adobe. The engineers say they lost up to $3 billion in wages from 2005-9, when the companies colluded in a scheme not to solicit one another’s employees. The collusion, according to the engineers, kept their pay lower than it would have been had the companies actually competed for talent.

The suit, brought after the Justice Department investigated the anti-recruiting scheme in 2010, has many riveting aspects, including emails and other documents that tarnish the reputation of Silicon Valley as competitive and of technology executives as a new breed of “don’t-be-evil” bosses, to cite Google’s informal motto.
