But some times when we ignore the existing staff and bring somebody from outside above them, there will be a problem for the members in the department and they never cooperate with the new boss. How the new boss brings the old employees working under him will bring him into his fold is the skill of the new employee. If the new employee thinks that he is much better than his seniors, then only a problem with the new employee will come.
On the reverse, we can see to the same extent, new comers are not considering the seniors as seniors as the new comers are qualified more over the seniors. They have some superiority complex in them and they do not respect the seniors. Some years back as I was given to look after branches administration also, I was under tour frequently all over India. To Assist me in factory work, my director asked me to take an assistant. I agreed and took a graduate assistant and as he hold an additional diploma, he kept in his mind that soon he would get promotion over mine. So, he behaved very rudely with others as of a Manager. Everybody complaints about him to me and my director. We called him and explained his situation and to handle employees very normally as we are in Personnel Department. But he started to say that the handling of employees should be very strict as to hold them in a limit etc., We decided to wait for some time and as we predicted he left the job before completing one year as he could not cope with our functioning.
So both the type of juniors as well seniors are in organisations.
