So it is saying 12 days leave with pay. Hence you cannot term it as CL and SL. you should term it as PL. for your company, giving only 12 days PL is mandatory as per the TN Shops and Establishment Act. Apart from that, there should be one weekly off and other holidays as per National Holidays and Festivals Act.
I hope I am able to clear your doubt.
