3) African Americans were treated unfairly by employers.
Explanation:
The Black Codes were laws that restricted the freedom of African Americans, they were created after the abolition of slavery during the Civil War.
African Americans were treated badly under those laws, especially when it comes to labor. They were forced to sign early labor contracts, if they did not agree with it they could be arrested, fined and forced into unpaid labor. African American workers were subjected to arrest, beating and forced labor. Orphans and kids would work into unpaid labor.
There were also restrictions to employers, anyone who offered higher wages to black laborer could be punished.
