Correct phrase is entitlement not availability.
Now either you are factory or an establishment.
Factory: Since CL / SL is not defined under the factories act, the entitlement will be governed by company's leave policy.
Establishment: If CL & SL is mentioned in the applicable shops act,the entitlement will be as per the provisions of shops act; if there is no mention of CL/ SL, the entitlement will be as per company's leave policy.
