Republic Day (January 26), Independence Day (August 15) and Gandhi Jayanti (October 2) are the three national holidays observed in India. On these days all institutions, irrespective of under which law they are covered, or whether they are public or private organizations or MNCs should necessarily remain closed.
But if for some reasons, on these national holidays if the employers wish to keep their organization functional, they need to obtain prior permission from concerned authorities. Also, the workers who work in organization on these national holidays are entitled to receive double wages for the day. (Though these national holidays are a matter of Central legislature, some states do have made provisions for compensatory leave to the workers who have worked on these national holidays, and this is over and above double wages for that day.
