Samuel Gompers, head of the American Federation of Labor (AFL), focused on economic goals for workers (like better wages, shorter workdays, increasing union membership) and favored "pure and simple" unionism, avoiding direct political party alignment. He prioritized collective bargaining and labor - related actions over union support for political parties.
