Human rights organizations have documented child labor in USA. According to a 2009 petition by Human Rights Watch: "Hundreds of thousands of children are employed as farm workers in the United States, often working 10 or more hours a day. They are often exposed to dangerous pesticides, experience high rates of injury, and suffer fatalities at five times the rate of other working youth. Their long hours contribute to alarming drop-out rates. Government statistics show that barely half ever finish high school. According to the National Safety Council, agriculture is the second most dangerous occupation in the United States. However, current US child labor laws allow child farm workers to work longer hours, at younger ages, and under more hazardous conditions than other working youths. While children in other sectors must be 12 to be employed and cannot work more than 3 hours on a school day, in agriculture, children can work at age 12 for unlimited hours before and after school."
