package means is not salary only. It is a combination of Brand, profile and salary. So if we get it then we never try to loose it. Career is like a train.

Employer are a platform. some platform are small, where train like express stop for one to two minute, means a good skilled person never stay long in a small organization, he can stop only when there is some problem, like to train crossing or incase of some technical problem.

Train like Rajdhani, will stay for a long time only in bigger platform or in a junction. so this all depend on what type of platform and train is it.
