from custom. Once an employee enters into a bonded relationships, they are characterised by asymmetry of information, opportunity, no time to search for alternative jobs and high exit costs. Estimates of bonded labour in India vary widely, depending on survey methods, assumptions and sources. Official Indian government estimates claim a few hundred thousand labourers are bonded labourers; while a 1978 estimate placed bonded labour in India to be 2.62 million. The 32nd National Sample Survey Organisation survey in India estimated 343,000 bonded labourers in 16 major states, of which 285,379 were located and freed by 1996. The major employment sectors for debt bonded labour include: agriculture, stone quarries, brick kilns, religious and temple workmen, pottery, rural weaving, fishing, forestry, betel and bidi workers, carpet, illegal mining and fireworks. Child labour has been found in family debt bonded situations. In each survey, debt bonded labourers have been found in unorganised, unincorporated sector. India enacted Bonded Labour System Abolition Act (1976) to prohibit any and all forms of bonded labour practice, to protect the bonded labour, and to criminalize individuals and entities that hire, keep or seek bonded labour. Child labour According to data from Census year 2011, number of child labourers is 10.1 million, 5.6 million boys and 4.5 million girls in India. Total of 152 million children, 64 million girls and 88 million boys are estimated to be in child labour globally, for almost one in ten of all children worldwide. Poverty, lack of schools, poor education infrastructure and growth of unorganised economy are considered as the most important causes of child labour in India. Article 24 of India's constitution prohibits child labour, but only in factories, mines or hazardous employment. The Indian Penal Code, the Juvenile Justice (care and protection) of Children Act-2000, and the Child Labour (Prohibition and Abolition) Act-1986 provide a basis in law to identify, prosecute and stop child labour in India. Nevertheless, child labour is observed in almost all unorganised, small scale, informal sectors of the Indian economy. Scholars suggest inflexibility and structure of India's labour market, size of informal economy, legal hurdles preventing industries from scaling up and lack of modern manufacturing technologies are major macroeconomic factors encouraging demand for and acceptability of child labour. Labour laws in India The labour laws of India originated and express the socio-political views of leaders such as Nehru from pre-1947 independence movement struggle. These laws were expanded
