Amid vast unemployment, India's biggest job creator short of labour

The challenge of retaining staff despite 12.2 crore people losing their jobs in India last month shows how difficult it will be for Modi to restart Asia’s No. 3 economy, where the bulk of the workforce comprises so-called informal labour that are denied security and benefits. Economists predict a rare contraction in national output.
