Of the Indian labour force, 93% are employed in the informal sector. So people in informal sector jobs have no protection, they have very little job security. In that context the other 7% who are in good jobs where they do have protection are under quite a lot of pressure. So I think there are huge difficulties in the implementation of labour law.
India has a whole panoply of labour laws but their implementation is of course extremely problematic. The fact that it has been possible for employers to greatly increase the use of contract labour precisely to avoid protective labour legislation over the last decade is an indication of that.
