A U.S. appeals court has revived a lawsuit against Meta Platforms, alleging bias against U.S. workers in favor of cheaper foreign labor. The 9th U.S. Circuit Court of Appeals ruled that discrimination against American workers extends to 'alienage' bias. The case involves Purushothaman Rajaram, a naturalized U.S. citizen seeking to represent a class of workers. Meta denies wrongdoing, but the decision sets up a potential Supreme Court case due to a circuit split on the issue. The ruling could impact hiring practices and diversity initiatives in the tech industry.
