Private companies -
If it's factory / warehouse EL would be 15. if Shop & Establishment PL would be 15 in a year. EL/PL can be encash twice or as per convenient of HR Policy through Basic + DA (Mostly companies doesn't separate DA from Basic)
Each get credited after 20 working days or 5 leaves on 4 month completion.
CL & SL would be same i.e. 1 CL / SL would get credited after completing 30 days as per Pro rata basis. means 12 CL. No Carry Forward.
Public holiday will remain close depend upon scope of job. if necessary for life, company may open. otherwise close.
Restricted holiday means employee can take two of all RH. (it's flexible not restricted actually).
For any confirmation revert me on the same.
