Answer:
The vast majority of labor was unpaid. The only enslaved person at Monticello who received something approximating a wage was George Granger, Sr., who was paid $65 a year (about half the wage of a white overseer) when he served as Monticello overseer.Life expectancy was short, on many plantations only 7-9 years.Industrial slaves worked twelve hours per day, six days per week. The only breaks they received were for a short lunch during the day, and Sunday or the occasional holiday during the week.Fearing that black literacy would prove a threat to the slave system -- which relied on slaves' dependence on masters -- whites in many colonies instituted laws forbidding slaves to learn to read or write and making it a crime for others to teach them.However, the health of plantation slaves was far worse than that of whites. Unsanitary conditions, inadequate nutrition and unrelenting hard labor made slaves highly susceptible to disease. Illnesses were generally not treated adequately, and slaves were often forced to work even when sick.Slaves were punished by whipping, shackling, beating, mutilation, branding, and/or imprisonment. Punishment was most often meted out in response to disobedience or perceived infractions, but masters or overseers sometimes abused slaves to assert dominance.
