Answer:
Racial discrimination and unequal labor treatment.
Step-by-step explanation:
Hello!
Between 1915 and 1930, a social movement was developed, which was characterized by the movement of black people from the southern states to the urban centers of the north of the country.
This internal migration was motivated by the worsening of racial relations and the intensification of acts of violence in the southern states. People expected to find a good social climate and better working conditions in the industries of the northern cities.
Upon arrival, they met with the rejection of workers of European origin who were established in those cities, since they saw them as competition for their jobs.
