@Somnath Jana As per Circular No. S/104, dated 07.08.2009 issued by the WBBSE, a teaching or non-teaching staff may enjoy only 13 CL in the sesssion 2011-’12 (From February, 2011 to December, 2011). As your date of joining is 22-06-2011, you are entitled to enjoy a maximum of 7 CL in the session 2011-12 (i.e., up to Dec,2011). So no question of enjoying 14 CL in the first two months arises in your case.
@Somnath Jana In your case the above mentioned rule is applicable as @gpgarain has mentioned above. Also, keep one thing in mind that CLs are meant to be availed in a proportional manner throughout the year. It is not as if you are entitled to enjoy all the allotted CLs in a single month. Most HMs follow this rule.
