Prashant Kumbhar,
Minimum Wages is fixed by the State Govt. on the basis of all India average of consumer price index.The state govt. is empowered to categorize the skills for scheduled employment in different industries. This categorization is primarily based on the craftsmanship to perform the task. Some states have also included educational qualification in fixing the minimum wages.
Since the wages are based on the job performed by him with required skill, one is free to engage person accordingly. However, if state notification has linked the categorization with educational qualification, needs to be checked before engaging such employees.
States like Karnataka has empowered Labour commissioner to decide the rate of wages of such employees who are engaged through contractor and carry out jobs similar to workmen engaged by principal employer . This notification is under Rule 25(iv) of the Contract Labour ( R & A) Karnataka Rules. Hence, you need to check the same with respect to your state.
Thanks,
