Inter State migrant workers are one of the much-marginalized sections of worker class. They not only have to leave their own state and place of residence, but also have to face several troubles in the way of searching for a livelihood and a decent living condition. Though there is a central legislation that ensures various kinds of rights to the interstate migrant workers, yet the effectiveness of the law is always in question. Under the backdrop of these scenarios, this paper tries to analyse the various aspects of interstate migrant labourers, the effectiveness of the laws protecting their rights and also suggesting some measures to make the law for effective and goal oriented.
