For example, in Persia, the situations and lives of such slaves could be better than those of common citizens. Forced labour Forced labour, or unfree labour, is sometimes used to describe an individual who is forced to work against their own will, under threat of violence or other punishment, but the generic term "unfree labour" is also used to describe chattel slavery, as well as any other situation in which a person is obliged to work against their own will, and a person's ability to work productively is under the complete control of another person.
