American labor unions are increasingly critical of President Donald Trump’s tariffs on imported products like steel from China. A growing number of union members question whether the tariffs will lead to more manufacturing jobs, better wages and working conditions. At the Bull Moose Tube steel piping factory in Georgia, 56 United Steel Workers union members have been barred from their workplace for more than six weeks. The union had rejected a new agreement with the company. The proposed deal offered a small wage increase, but asked workers to pay a lot more for their healthcare. “I’m going backwards instead of forwards,” said steelworker David Horton. He has been off the job without pay since August 22. Employees have been demonstrating near the factory while the company brought in non-union workers during the labor dispute.
