You can ask the employees to work on a declared holiday by informing them in advance in the prescribed form and sending a copy of the same to the Labor Officer. This should be on one condition: the employee shall be paid double the rate of wages for the day and shall be given another day as a compensatory holiday.
Right of the Employer to Call Employees on Holidays
Asking the workers to work on a holiday following the above is a right of the employer. However, this 8-hour working will be considered as overtime work, and when the overtime exceeds the maximum permitted as per the state rules, you will be in trouble. You can also say that abstaining from overtime work is insubordination, but the same can be challenged by the workers and union, saying that working on a holiday is purely voluntary and no employee shall be compelled to work on a holiday. By calling them for work, the very purpose of declaring the holidays for the year in advance will be defeated.
Considerations for Holiday Work
Therefore, the issue has to be faced considering the importance of holidays, religious sentiments, etc.
