Few seniors have given their valuable inputs, and I hope that will help you understand the matters better. Going by the same approach, I would like to add a few more points on the questions you mentioned in your last post. As you have mentioned that you would like to understand concepts in line with the Shops and Establishment Act, I will try to answer accordingly, assuming your location to be Delhi (correct me if I am wrong).
However, I personally feel that private organizations work within the framework suggested by the Acts and Laws, but not everything can always be strictly followed as per the act/law. That's where organizations use their own discretion to implement and run day-to-day affairs while not largely deviating from the given framework.
Question 1
I guess it is one of the most spoken-about topics in this forum or even others, and maybe between employees and HR, a lot of views have been put on this. To the best of my knowledge and as per the inputs from my HR network, I have seen it as a company-specific decision. Some companies include any holiday/birthday-off/weekly-off as leave if they fall in continuous leaves taken by the employee, whereas some only take into consideration all days as leaves excluding the above-mentioned days. Some companies take all the above-mentioned days as leaves only if they exceed the pre-decided continuous leaves that one takes as per the policy.
The Delhi Shop and Establishment Act mentions that a holiday should be paid but has not set a very clear guideline for how it should be included in the continuous leaves. You can decide in consultation with your management which option you would like to formulate and implement in this regard.
Question 2
Prefix & Suffix stands for a leave before and after another leave/holiday/weekly-off/birthday-off. For example, as you mentioned in Question no. 1, the employee has taken leave on 01-Oct-11, 02-Oct-11, and 03-Oct-11. Now, as per the existing policy of the company, 02-Oct-11 is a national holiday. So if the person has taken leave on 01-Oct-11 as a prefix leave and again took another leave on 03-Oct-11 as a suffix leave, then the company can take it as 3 days leave as it has a prefix of 01-Oct-11 and a suffix leave of 03-Oct-11, having 02-Oct-11 in between. In contrast, it can be considered as only 2 days leave, i.e., only for 01-Oct and 03-Oct.
As you have mentioned that your 3rd query has been answered, I will not be writing more on it.
Hope this will help.
Thanks,
Prashant
