Boss plays a very important role in the carreer of an individual. How far the boss will help the subordinate will depend on how the subordinate manages insecurity , ego and idiosyncrasies of the boss.
To manage the insecurity of the boss, the subordinate must demonstrate his loyality to the boss.This involves
1.0 Keeping the boss informed about the developments that the subordinate comes to know of which might be of interest to the boss.
2.0 Helping the boss to repair the damage that might have been caused by the boss's mistake.
3.0 Protecting the boss's image when the boss is being discussed
Furthermore , every human being has an ego, and believe it or not, the boss is also a human being. If the ego is hurt, relationships will be affected adversely. A subtle pampering of the ego helps to build a good relationship. I have seen one case where one hotel server could rise up to the chief Executive of the Hotel by satisfying the ego of his boss. But his rise was also as dramatic as his fall.
Everybody has idiosyncrasies- everybody acquires habits in his life. So does the Boss : and these are difficult to change. The subordinate has to adjust his habits with those of the Boss.
