The term 'kind of labor' can refer to two different types of jobs: MENIAL labor and SLAVE labor. MENIAL labor is a type of work that requires little skill or training and is often considered to be tedious or unpleasant. SLAVE labor, on the other hand, is a form of forced labor in which people are held against their will and forced to work for no pay. Both of these types of labor are still present in many parts of the world today.
