Explanation:
Samuel Gompers was the head of the largest labor federation of America known as American Federation of Labor. This organization comprised of workers that were skilled artisans, weavers, carpenters etc. He also headed the labor movement after actively forming a union of workers in the cigar industry. He himself was a cigar worker and thus could relate to the plight of the people working there. Young aged children were employed in cigar factories and the wage and benefits were not even enough to support survival of one.
Thus, Samuel arouses his voice to stand against the injustices done to the workers in cigar factory which later turned out to be mass movement.
