The Minimum Wages Act of 1948 was passed to prevent exploitation of workers in industries where wages were low and bargaining power was weak. It empowers the central and state governments to fix minimum wage rates for scheduled industries. The Act covers all workers regardless of skill level or employment type. It requires employers to pay workers no less than the minimum wage set for their class of work and maintain registers documenting wages paid. The Act has been amended over time to regularly revise wages, expand coverage, and strengthen implementation.
