Say, the last period continue to 4-30 p.m. A or few teacher(s) has/have to given their departure time-4-30 p.m. though they left school 4-15 p.m. It is possible, if the M.C. is agreed to allow to do so. But think a case, if the A.I./S.I./D.I. or their representatives are visited the school in the eleventh hours of the school and found that the 5 or 6 or 8 etc. teachers had gone before the time of departure (4-30) giving the time of departure (4-30), then what will be happened? Is the M.C. managed the case?
By the by , no doubt your M.C. is very kind-heart.
No,there will be no reflection about the time of arrival and departure.
Thanks a lot.
