Factory
From Arthapedia
Under the Factories Act 1948, factory means any space where ten or more workers are working or were working on any day in the preceding 12 months. They should be engaged in a manufacturing activity with the aid of power. Alternatively, when twenty or more workers are working in such a process without power, such a space would also be a factory. It excludes a mine , a mobile operation unit of armed forces, a railway running shed, hotel, restaurant or any eating place.
