Why did migrant workers face competition for jobs?

Migrant workers often faced competition for jobs due to several factors, including an oversupply of labor in certain regions and industries, which heightened the competition among workers for limited positions. Additionally, local workers sometimes viewed migrant labor as a threat to their job security, leading to tensions and competition. Economic conditions, such as high unemployment rates or downturns in specific sectors, further exacerbated this competition. Lastly, varying skill levels and wage expectations among migrant workers contributed to a complex job market where competition was intensified.
