Does a Subcontractor with 20+ Workers Need a License if the Main Contractor Isn't the Employer?

I want to know if a subcontractor who has 20 or more manpower in the construction area requires a license. The main contractor holds a license for all workers under whom the work is carried out, but the main contractor is not a principal employer. Please suggest how I can solve this problem.

What is the contention of the principal employer? As a matter of fact, if the main contractor obtained the labor license, it means the subcontractors are also covered under the same. The contractor cannot issue the Form V to the subcontractors. If the principal employer issues the Form V through the contractor, then only the subcontractor can apply for the labor license. Otherwise, it is not possible to obtain the labor license.

Regards,
