Hi Amit,
The topic is really very serious and interesting.
If the principal employer has engaged some workers through a contractor or outside agencies, it is the responsibility of the outside agency to deposit the ESI Contribution of the workers engaged by the contractor.
However, what the ESI authorities are doing is issuing notices to the principal employer for not submitting the ESI Contribution of the workers engaged by outside agencies. In fact, this is the responsibility of the outside agencies/job contractor, but in ESI, nobody bothers about it.
In the case of outsourcing work/job entrusted to outside parties where no supervision is involved by the principal employer or by his agent, the persons to whom the outsourcing has been done or their employees will not become the employees of the principal employer automatically. Hence, any amount paid to the contractors to whom the job work is entrusted, no contribution is payable on the said amount by the principal employer.
However, ESI authorities are not taking care of the judgments given by the various High Courts and the Honorable Supreme Court of India; they are only minting money by issuing notices to the principal employer.
I hope the matter is clear to you.
Best Regards,
Sushma
