Probably United Mine Workers or United Steel Workers they will organize anyone!
But seriously all the respect in the world to both of those Unions. They made conditions in my part of the country. Many a family member belonged to both. I even held a UMWA Construction ticket for awhile before I got into the International Brotherhood of Electrical Workers. I have heard but don't know if it is true that the Taxi Cab drivers in NY City belong to the IBEW!
