The Minimum Wages Act of 1948 was passed to protect unorganized workers in certain industries by establishing minimum wage rates. The Act aims to ensure wages are enough not just for a worker's subsistence but to maintain their work efficiency. It empowers the appropriate government to fix minimum wages for scheduled employments where exploitation is common. Key objectives include preventing exploitation, empowering governments to set and revise wages regularly, and applying the law widely in organized sectors. The Act outlines procedures for fixing and revising wages every five years and establishes advisory boards. It regulates payment and overtime wages, and penalties are prescribed for paying less than minimum wage.
