Understanding Minimum Wage Discrepancies in India
The Constitution of India has provided equal powers to the Union (Central Government) and State Government on the items mentioned in the Concurrent List (Labour and Employment is one in the list). India is a vast country, and every state is different from others in many aspects. As such, minimum wages vary from state to state, declared by considering the Consumer Price Index/Cost of Living Index of the particular state. For Central Government undertakings, minimum wages are fixed by the Central Labour Department. Similarly, for State Government undertakings, the State Labour Department sets the minimum wages. This is why wages differ among states.
However, the higher of the central or state wage must be paid to the workmen, regardless of the competent authority's jurisdiction (Central or State). For example, if two factories (of the same schedule of employment) are located in the same state, one under the Central Government and another under State Government jurisdiction, the State Government notified wages must be paid in both factories if the Central Government minimum wages are lower.
Hope this clears any ambiguity.
