The Minimum Wages Act, 1948 aims to prevent exploitation of labor by ensuring a minimum wage for scheduled employments. It empowers central and state governments to fix and revise minimum wages in scheduled industries through committees with equal employer and employee representation. The Act defines key terms and sets rules for payment of wages, working hours, overtime rates, and maintenance of records. Employers failing to pay minimum wages can face imprisonment of up to 6 months, fines, or both.
