There is no such rule in WBSR. 14 days CL is admissible to a Govt. Employee through out the year. For a new entrant in service a proportionate number of CL is admissible to him/ her. You can take 2 CL on a single month, no problem.
Sir, I don’t think it is necessary. You have already got your health scheme card, I hope. While claiming reimbursement, the card itself is the record of your enrollment.
