Since Sept. 15, 40,000 union workers have been working under an expired contract. The union voted 95% in favor of a strike authorization on Sept. 26, which means a citywide strike can be called at any moment.

"We have a history and tradition here in Las Vegas of civil disobedience," said Ted Pappageorge, secretary-treasurer and chief negotiator for the union during a Monday press call. "That means when you believe that there's something unjust going on, that you will send a message and take an arrest in a peaceful, nonviolent action. To send a message that we're disciplined, we're organized, and we're strong, and we're ready to fight."
