Thousands of hotel workers in Las Vegas fighting for new union contracts are rallying on the city's iconic Strip. Dozens of workers snarled traffic during rush hour Wednesday evening. They're vowing to be arrested to bring attention to the labor union’s negotiations with three major casino companies. Workers sat in two separate circles across multiple lanes, stopping traffic in both directions. Police officers stood by with zip ties but did not immediately make arrests. The Culinary Workers Union said ahead of the protest that 75 workers could be arrested for “civil disobedience” between the Bellagio and Paris Las Vegas resorts.
