If you want to understand the high tech labor market in the United States, a good place to start might be one of these stories about a lawsuit in the U.S. District Court in California.

These stories trace the progress of legal actions against some of America’s best-known tech companies over their attempts to suppress their employees’ wages through anti-competitive “no-poaching” agreements.  The Department of Justice found evidence that Intel, Adobe Systems, Google, Apple, Pixar, and Intuit made  secret agreements not to call each others’ employees with job offers, thereby reducing job opportunities and salaries in the industry. DOJ induced the six companies to settle an anti-trust suit in 2010 with a promise not to engage in similar restraints on trade in the future. The companies paid no damages and admitted no violations of anti-trust law, but the employees who had been hurt by the practices were not satisfied.

Employees filed suit against the six companies and Lucasfilm in federal court alleging an illegal conspiracy to restrain wages and salaries and seeking damages.  When the companies tried to have the suit dismissed, the district court judge sided with the plaintiffs, and in January, according to Phys.org, Judge Lucy Koh ruled that the case should proceed to trial and that Apple CEO Tim Cook, Google Chairman Eric Schmidt and Intel chief Paul Ottelini may be questioned by plaintiffs’ attorneys about their roles in the alleged conspiracy. The trial, reportedly, will take place in November.

I recommend keeping this case in mind when it comes time to evaluate the companies’ claims that their interest in bringing skilled guestworkers to the U.S. has nothing to do with getting cheaper labor. Never mind that the H-1B visa, which ties employees to a single employer for 6 years or more, is a bigger restraint on employee mobility than a no-poaching agreement.
