Except Maternity leave and CL , an additional teacher can not enjoy any other leaves. See the G.O. NO. 1541-Edn (S) /21-2/77, dated 15.12.1977 posted by our administrator, May,10,2012.
I enclosed a clarification of above leave.
In exceptional case/s like urgent medical cause, ML can be availed on condition that as soon as the post get retained, ML taken will be adjusted with the accrued quantity of ML w.e.f. the date of joining upto the date of retention. One on additional post can not avail ML but leave account gets credited as usual. The MC can forward such cases to the WBBSE for approval/consent.
