What was the roll of the government in the battles between unions and big business from 1870's-1920's?

From the 1870s to the 1920s, the government often sided with big business in the conflicts between labor unions and employers. This was evident through the use of legal measures, such as injunctions and anti-strike laws, to suppress labor actions. Additionally, state and federal troops were sometimes deployed to break up strikes and maintain order, reflecting a pro-business stance. Overall, government policies and interventions typically favored corporate interests over the rights of workers and unions during this period.
