Thank you all for the reply, @Natraj.
1. Thank you, sir. I still have a doubt. Suppose the daily basic + VDA = 312. If the person is working for 26 days, we have to give 26 * 312 = 8112. If the person is not working for four Sundays, how much do we have to pay for this period? Is it 1/6th of 8112 = 1352, or simply 8112 for the whole month? Kindly clarify, sir.
2. If we are only giving 8112 for the whole month (26 days of work), what about those four Sundays? Suppose a substitute is working on those four Sundays. Do we have to give a salary to that substitute for those four days?
