This is mainly because of the thought that others do not know anything over him. Once I told in my office projects officer that next day would power cut as mentioned in newspaper and asked him to get additional quantity of diesel for genset. He,as usual, did not accepted. On the next day sharply by 9.00 am. power went off. By 2.30 pm diesel got exhausted. He got bulb from production manager as well from GM.
In official matters sometimes, the big boss thinks that his views are correct and if somebody else tells something good also can't digest. Then what I feel is we should keep silent and implement the suggestions given by him and the result good or bad should be to his account. He may learn by doing mistakes.
If somebody points out us, we should take it in the correct perspective and analyse ourselves to see that whether by implementing the suggestions we may get benefitted. We should never ignore the points of others.
