Why did labor unions oppose immigrants in the 1880's?

Answer 1

Immigrants in the 1880's did not oppose their low wages.

The central job of a union is to limit the supply of labor from which employers are allowed to hire. Immigrants raised the supply and thus lowered the cost of labor.

Answer 2

they had opposed the Mexican immigrants because they did not know any English. the Americans had no way to communicate with them.

Nope. Unions did not care whether workers spoke only a foreign language. If that was a problem, it was a prob for the EMPLOYER>

Unions oppose immigrants because they increase the supply of labor and lower the cost of labor. More competition for each available job. And if unions strike, replacement is easier.

all those answers r dumb especially the one above mine its because the believed that immigrants took jobs from native-born americans

Answer 3

Immigrants were willing to work for relatively low wages
