Confused About New Salary Cycle: Should First Month Be Full or Prorated?

Our organization wants to start a new pay pattern where the salary month runs from the 25th to the 25th, ensuring that employees receive their salary on the 1st of each month. However, in the first month, we have calculated the salary for only 25 days, from the 1st to the 25th. Next month's payment will cover the period from the 26th of April to the 25th of May, ensuring a full month's salary.

I believe this calculation is incorrect. Please advise on how we should handle the payment for the first month. Should it be a full salary for the 25 days or a prorated amount for 25 days?

Thank you for your guidance.

Your work is perfectly okay. For the first month, in view of the rationalization of wage period, only 25 days' salary could be paid. If any workmen are covered under the Industrial Disputes Act, keeping them in agreement with this amount constitutes a change in service conditions and requires a 9-A Notice to the workmen.
