Among them nine are minors…rescued labourers alleged that each worker was being paid just Rs. 300 per week, which is against the minimum…While the migrated labourers claimed that they had been confined inside the quarry boundary, the local residents have different versions about the allegations of bonded labour system, said Mr. Naik. The local residents have reportedly said that they had hired the rescued labourers on several occasions.
