Yes, the rejection of unionization by skilled workers was a significant factor in the slow growth of labor unions in the United States during the 19th century. Skilled workers often viewed unions as a threat to their individual bargaining power and job security. This reluctance to join unions hindered the overall growth and effectiveness of the labor movement during that time period.
