Final answer:
The organization that worked to help former slaves find employment on plantations and negotiated contracts was involved with landowners, specifically during the Reconstruction era when sharecropping was prevalent.
Step-by-step explanation:
The organization worked to help former slaves find employment on plantations and negotiated contracts with landowners. After the Civil War, during the Reconstruction era, sharecropping became widespread in the South as a way for freed slaves and poor whites to work on land they did not own. The system was heavily skewed in favor of the landowners, who would rent out their land in exchange for a significant portion of the crops produced, often leading to a cycle of debt for the sharecroppers. Organizations like the Bureau of Refugees, Freedmen, and Abandoned Lands, also known as the Freedmen's Bureau, sought to protect the rights of former slaves by negotiating contracts and setting up courts where they could seek redress for abuses.
