This is an usual query,how ever would like to clarify from seniors as to who will be held responsible for non compliance ,Principal employer or the contractor , if the principal employer in spite of Knowing about all the statutes related of contract work awards the contract to the contractor on adhoc price.Later it is revealed by the labour inspector that compliance is not being followed properly... by the contractor.While contractor pleads what ever he receives from principal employer is the mere cost of salary which does not include any statutory deduction.Note there does not exist any written agreement for this work assigned.
