Read the following secondary source, then describe at least one cause and one effect of the Homestead Strike:

Homestead Strike
The first and bloodiest of a series of industrial strikes in the 1890s, the Homestead Strike took place at the Carnegie Steel Company plant in Homestead, Pa., in 1892. It was precipitated when company manager Henry Clay Frick sought to impose a wage cut. When the Amalgamated Association of Iron, Steel, and Tin Workers refused his terms and called a strike on June 29, Frick brought in about 300 Pinkerton detectives to run the plant. On July 6 an armed clash occurred between workers and detectives, in which several were killed; soon afterward, the state militia was sent in. Under the soldiers' protection, nonunion laborers manned the steel mills from July 12 to November 20, when the strike collapsed. Frick's success gravely weakened unionism in the steel industry, which was not unionized successfully until the 1930s.

One cause of the Homestead Strike was the decision by Henry Clay Frick, the company manager at Carnegie Steel, to impose a wage cut. This wage cut was seen as a significant reduction in the workers' pay and led to dissatisfaction among the Amalgamated Association of Iron, Steel, and Tin Workers, who then called for a strike.

One effect of the Homestead Strike was the violent clash between workers and Pinkerton detectives. This clash resulted in several deaths and heightened tensions between the two parties involved. As a response to the violence, the state militia was sent in to restore order and protect the nonunion laborers who were brought in to replace the striking workers. This ultimately led to the defeat of the strike and weakened unionism in the steel industry, preventing successful unionization until the 1930s.

One cause of the Homestead Strike was the wage cut imposed by company manager Henry Clay Frick. The workers, represented by the Amalgamated Association of Iron, Steel, and Tin Workers, refused the wage cut and called for a strike on June 29, 1892. This disagreement and refusal to accept the wage cut led to the escalation of the conflict.

One effect of the Homestead Strike was the weakening of unionism in the steel industry. After the armed clash between workers and detectives, the state militia was sent in and nonunion laborers were brought in to man the steel mills. This allowed the company to continue operating without the involvement of unionized workers. The strike ultimately collapsed on November 20, 1892, and this success for Frick gravely weakened unionism in the steel industry. It took several more decades before successful unionization in the steel industry occurred in the 1930s.

To find the cause and effect of the Homestead Strike, we need to analyze the information from the given secondary source. According to the source, the cause of the Homestead Strike was the company manager, Henry Clay Frick, seeking to impose a wage cut on the workers. When the Amalgamated Association of Iron, Steel, and Tin Workers refused the wage cuts and called for a strike, Frick brought in Pinkerton detectives to run the plant.

The effect of the Homestead Strike was a violent clash between the striking workers and the Pinkerton detectives on July 6th, resulting in several deaths. Following this clash, the state militia was sent in to stop the violence. With the militia's protection, nonunion laborers were brought in to replace the striking workers from July 12th to November 20th, leading to the collapse of the strike.

As a result of the strike's failure, the success of Frick's strategy seriously weakened unionism in the steel industry. It was not until the 1930s that the steel industry was successfully unionized again.

To summarize:
- Cause: Henry Clay Frick's attempt to impose a wage cut.
- Effect: Violent clash between workers and Pinkerton detectives, collapse of the strike, weakening of unionism in the steel industry.
