The Minimum Wages Act of 1948 aims to set minimum wages for skilled and unskilled laborers in India based on a living wage standard. It outlines the history of minimum wage legislation in India from 1920 onwards and recommendations to establish wage boards. Minimum wages are revised every 5 years based on a cost of living index and differ across states, sectors, skills and occupations. While the Act aims to protect workers, there are limitations such as unemployment, inflation, exemptions and lack of awareness. There have been conflicts between central and state governments over fixing wages for programs like MGNREGA relative to state-level minimum wages.
