Hi, here are a few inputs:
Leave policy alignment
It depends on company policy how the leave policy is aligned and agreed upon. If any leave earned by an employee should not be considered for prefix or suffix as this is an eligibility of such an employee. For example, 20 working days, 1 EL, six-day continuous work, 1 day of rest, or declared holidays, etc.
Consideration of declared holidays
Some establishments will not consider declared holidays as leaves which are approved by the labor department like national and festival holidays.
As a practice, other than national or festival holidays, earned leaves, all other leaves may be treated as part of leaves, like how it is treated for ESI or maternity leaves.
