Explanation:

Before 1860, the American agricultural economy was present but after this time the agricultural economy changed to a new medium called the Industrial economy.Across Europe 55,000 agencies recruited temporary workers across countries and this included immigrants also.Employers outsource many workers and deepen their short term contracts.Due to this immigrants across countries working on temporary basis demanded good wages and incentives.Strikes took place due to this.
