ESI Coverage Clarification
If the contractor employs his workers in your factory, which is situated in a non-coverage area under ESI, they need not be covered under ESI by the contractor. Hope the matter is clarified to you.
ESI Corporation's Initiatives
ESI Corporation, under the Government of India, has already initiated action to cover the Act in various districts in the country. Hence, when the area where your factory is situated falls under ESI coverage, you can apply for ESI registration.
