Dear Friend,
As per the Factories Act, there is no mention of CL & SL. The Factories Act speaks about Earned Leave at the rate of 1 EL for every 20 actual working days. If you have any provisions in your Certified Standing Order, Leave Rules, or HR Handbook, then you need to follow accordingly.
If it is the Shops & Establishments Act, then it is 12 CL, 12 SL, and 15 EL.
Thanks and regards,
Kamesh
