Teachers and demonstrators hold signs and chant during a rally outside the West Virginia Capitol in Charleston, West Virginia, U.S., on Friday, March 2, 2018. A week ago, thousands of public school teachers in West Virginia went out on strike, a rare but familiar union-organized action to protest low wages and rising health-care costs. Tuesday night, state union leaders and the Governor Jim Justice reached a deal, and the teachers were expected to be back at work on Thursday, but they didn't go. Unsatisfied with the resolution, they stayed on the picket line, mounting one of the country's biggest unauthorized "wildcat" strikes in decades. Photographer: Scott Heins/Bloomberg via Getty Images
