Answer:
The correct answer is: Labor unions discriminated against Chinese immigrants and did not allow them to join.
Step-by-step explanation:
In the late 1800s, many labor unions in the United States were formed to protect the interests of workers and improve their working conditions. However, these unions often excluded Chinese immigrants from their ranks, viewing them as a threat to their own jobs and wages. Chinese immigrants were also subjected to discrimination and violence from other workers, particularly in industries such as mining and railroad construction.
One notable example of labor union discrimination against Chinese immigrants was the Chinese Exclusion Act of 1882, which was supported by many labor unions at the time. The act prohibited Chinese immigrants from entering the United States and denied citizenship to those already in the country. This law remained in effect until 1943.
Overall, labor unions in the 1800s did not treat Chinese immigrants well and actively worked to exclude them from their ranks and limit their employment opportunities.
