Why, skilled workers belong to an American Federation of Labor craft union, and unskilled workers belong to a Congress of Industrial Organizations union, of course. Skilled workers are trained by the union through apprenticeships. Unskilled workers are trained, minimally, by their foremen. And the CIO is a Communist front, say the bosses. That's the US classic labor history view.
