When did the Central Plan Scheme for the rehabilitation of bonded labourers start?

Explanation: Bonded labour is prohibited in India by Articles 21 and 23 of the Constitution. In 1976 Bonded Labour System (Abolition) Act was enacted. Under it, identification, release and rehabilitation of freed bonded labour is the direct responsibility of the concerned state/union territory governments. In order to assist the state/UT governments in the rehabilitation of identified and released bonded labourers, Central Plan Scheme was started in 1978. As per the Scheme, the central government bears 100% of expenditure and the states are not required to pay any contribution for the purpose of cash rehabilitation assistance, surveys and awareness campaigns for bonded labour.
