If the factory/shop is otherwise supposed to be covered by the ESIC, you may have to show to the concerned authorities that you are providing better facilities and benefits than those offered by the ESIC. You have to apply for exemption which may be granted an exemption for a year which has to be renewed. Please read Section 87-89 under chapter VIII of the ESIC Act for details.
