By 1900, immigrants working in factories were making abysmal wages and were working long hours to try to survive. Despite labor restrictions, employers
often sought to persuade workers to work longer hours with "voluntary agreements". More significant than the long hours were the workers' concerns about

a. violence in the workplace by employers towards low-wage employees

b. restrictions of employment opportunities for workers of specific ethnic groups

c. termination of employment with no provocation and no opportunity to petition the termination

d. unsafe working conditions
