"Slave-labor" refers to the practice of forcing people to work against their will, often without pay and under severe conditions. To avoid using this loaded term, there are several synonyms that can be substituted, such as forced labor, bonded labor, indentured labor, or human trafficking. These words can help to describe the same concept without invoking the painful history associated with the term "slave." It is important to always use language that is respectful and sensitive to those affected by such injustices, and to be aware of the power dynamics and systemic inequalities that contribute to the exploitation of vulnerable individuals.
