How did Andrew Carnegie feel about unions?

Andrew Carnegie had a complex relationship with labor unions. Initially, he supported workers' rights and believed in fair treatment, but his stance shifted significantly after the Homestead Strike of 1892. During this violent conflict between strikers and private security forces, Carnegie sided with management, viewing unions as a threat to business operations and economic progress. Ultimately, he believed that while workers deserved fair wages, unions could disrupt the harmony between labor and capital.
