The Minimum Wages Act 1948 generally specifies minimum wage rates on a per day basis, and extends to the entire country and is revised within a period of not less than five years, however there is a provision to increase dearness allowance every two years. The norms in fixing and revision of minimum wages were first recommended by ILC, 1957.

Revision of minimum wage rates is based on a 'cost of living index' and wages can be fixed for an entire state, part of the state, class or classes and employments pertaining to these categories. The fixation of wages is based on the norms mentioned and a wage board (different for different industry).

Under the Minimum Wages Act, State and Central Governments have the power to fix and revise minimum wages. The act specifies that the "appropriate" government should fix the wages i.e. if the wages to be fixed are in relation to any authority of Central government or Railway administration then the Central government fixes it. However, if the wage rate is to be fixed or revised for a scheduled employment, the respective state governments fix it. The Centre fixes the National floor level Minimum Wage that
