If you grant half-day earned leave for the second half on Saturday and half-day earned leave for the first half on Monday, then you are required to pay for Sunday, i.e., the weekly off, also if your pay system is based on 30 days. On the other hand, if there is a prefix or suffix to the leave of CL or SL, the intervening weekly off will also be treated as leave. If there is no leave balance in the credit of the employee who applies for leave as stated above, he has to lose two days' pay.
