Explanation:

Labor strikes are one of the responses that the labor organization gave towards the uneven or inhumane policies of the factory owners. The strikes are called up by the union leaders. During the 1880s, more than 20,000 strikes were recorded in protest of the unjust and evil policies. On the other hand, the authorities and the government together tried to curb and oppose the strikes. For this purpose, the local police, the state militias, and federal troops were given the task of ending the strikes.
