Striking Amazon and Starbucks workers in California and elsewhere have long pushed for union contracts. The Trump administration is unlikely to be on their side.

America’s unions have had a banner year. In November 33,000 machinists returned to their stations at Boeing having won a 38% wage increase over four years. Their victory followed a seven-week strike that brought the planemaker to its knees.

Amazon delivery drivers and Starbucks baristas are on strike in a handful of U.S. cities as they seek to exert pressure on the two major companies to recognize them as unionized employees or to meet demands for an inaugural labor contract.
