By Dan Levine SAN FRANCISCO (Reuters) – A U.S. judge on Friday rejected a request from Apple, Google and two other tech companies to avoid a trial in a class action lawsuit alleging a scheme to drive down wages. Trial is scheduled to begin in May. Apple, Google, Intel and Adobe asked for a judgment in their favor without a trial, arguing that any no-hire agreements between the companies were reached independently, and were not part of an overarching conspiracy. U.S. District Judge Lucy Koh in San Jose, Calif., however, rejected that argument. An Intel spokesman said the company is studying the ruling, and representatives for Google and Apple declined to comment.
