Social security is the fundamental building block of just and equitable society. he modern concept of social security traces its origin to industrial revolution. According to International Labour Organization (ILO), "social protection floor" defines the basic set of rights, services nad facilities that every citizen enjoys. In the Indian context, given the vast and heterogeneous characteristic of the workforce, the informalization of employment has altered the meaning and scope of social security. On one hand, it denotes low level of social protection and high vulnerability and on the other hand, lack of institutional arrangements and policy. According to NSSO (2012), in 2009-10, 71 percent of workers in urban areas and 67 percent workers in rural areas were in the informal sector. These primarily constitutes migrants who are in transit from one contract to another. The issue of welfare and security of such workers has been bypassed in current political debate, setting the stage for worker unrests. There needs to be recognition of informal employment and how ongoing amendments can be extended to cover them.
