This is an unusual query; however, I would like to clarify from seniors who will be held responsible for non-compliance - the principal employer or the contractor. If the principal employer, in spite of knowing about all the statutes related to contract work, awards the contract to the contractor at an ad hoc price, and later it is revealed by the labor inspector that compliance is not being followed properly by the contractor, while the contractor pleads that whatever he receives from the principal employer is merely the cost of salary which does not include any statutory deductions. Note that there does not exist any written agreement for this work assigned.
