Thirteen labor unions and the AFL-CIO’s Metal Trades Department filed a lawsuit against the Trump administration Friday to stop the White House’s effort to limit government employees’ practice of doing union work instead of their jobs while being paid by taxpayers.

“On May 25, the Friday before Memorial Day, President Trump signed three executive orders that the affiliated unions of the Metal Trades Department, AFL-CIO, contends violated the due process and collective bargaining rights of workers employed by the federal government,” stated Metal Trades Department President James Hart. “The president’s executive order is an attack on our hard-working members and their rights.”
