he United Nations says changes to India's child labour law which permit children to work for their families and reduce the number of banned occupations for adolescents will disadvantage vulnerable groups such as tribals and lower-caste communities...With child labour rates highest among tribal and lower caste communities at almost 7 percent and 4 percent respectively, UNICEF said, the changes could have an adverse impact on these especially marginalised and impoverished communities...More than half of India's child workers labour in agriculture and over a quarter in manufacturing - embroidering clothes, weaving carpets or making match sticks. Children also work in restaurants and hotels, and as domestic workers.
