The Department of Justice has sued Facebook. The lawsuit alleges that Facebook has discriminated against U.S. workers by reserving positions for temporary visa holders. The DOJ also alleges that Facebook failed to consider qualified and available domestic workers. The DOJ is seeking civil penalties, back pay on behalf of domestic workers that were allegedly denied employment and other relief to prevent future discrimination.
