I do not think that a legal commentary or case law is required to establish it. A factory where a manufacturing activity is carried out is covered under the Factories Act, mine is covered under the Mines Act or a Plantation is covered under Plantation Labour Act. All these Act speak about registration of the establishment and provide for health, safety and welfare of the people employed therein. An establishment which will not come under these Acts like an administrative office, sales office or depot where there is only support functions carried out should also be registered and follow some guidelines for health, safety and welfare of the people employed in such offices. Obviously an admin. office which is situated within the boundaries of the factory, mine or plantation will be under the Factories Act, Mines Act or Plantation Act, as the case may be. Those outside the boundaries or situated away from the factory, mine or plantation will not be covered by the respective Act and for that the State Act meant for shops and commercial establishments will apply.
