Final answer:
During the Civil War, enslaved African Americans often engaged in work slowdowns.
Step-by-step explanation:
During the Civil War, slavery was a contentious issue in the United States. While the Emancipation Proclamation declared the freedom of enslaved African Americans in the Confederate states, it did not immediately end slavery. In the North, there were still some individuals who owned slaves, often referred to as Northern slaveholders. However, it was the enslaved African Americans who often engaged in work slowdowns as a form of protest and resistance against their oppressive conditions.
