Bonded labour, or debt bondage, is a form of modern slavery where people are forced to work to repay debts or other obligations. It is estimated that 20 million people worldwide are in bonded labour. In India, bonded labour has existed for thousands of years within the caste system and continues today in agricultural relationships. The Bonded Labour System (Abolition) Act was passed in 1976 to abolish bonded labour but has failed to meet its goals due to a lack of enforcement by district authorities. NGOs like Bachpan Bachao Andolan work to rescue and rehabilitate bonded labourers, especially children, but more needs to be done by the government to enforce laws against bonded labour and support rehabilitation efforts.
