Leave structure differs from company to company. Most companies put 8 SL, 8 CL and 16 PL. And it is been paid at pro-rata basis.. means if its 8 number of leaves in a year then after 3 months one will be eligible for only 2 SL and same with other types of leaves.. Moreover if Leave calender is from January to December and someone joins in April then for the calender year he will be eligible for only 6 CL, SL and 12 PL.
Out of these 3 types of leaves, CL can't be carried forward for the next year. While PL and SL can be carried forward..
Some companies encash the available PL at the end of the year while some companies do the cash only at the time of separation from the company.
Hope now your query has been answered.
