Dear Chennaiin,
I hope that you can very well distinguish and understand the move of changing a holiday in its entirety and that of requiring the employees to work on such a holiday on business exigencies are different. I also think that every State National and Festival holidays Act recognizes the necessity of running certain industrial establishments like transports, communication, medical services, continuous process industries etc., even on such holidays in public interest as well as impossibility of shutting down of operations. That's why the options of availing of the holiday or working on double wages or for an alternative holiday within three days before or after the day are given to the employees themselves under the Acts. Therefore, we can not decry the act of working of such establishments on such holidays as per the procedure of Law as an unpatriotic gesture or the particular provision for exercising legal choice as a loophole. In my opinion the negative response is apt in the face of the wrong or misleading phraseology of the query despite the presence of lawful choices in the very Statute.
