We're running towards the complete loss of the identification between employee and company.
As it happens in sports or in real life , a union isn't forever!
In sport it doesn't exist the "flag-man" that identify himself and his career with the colours of only one team, in life it doesn't exist a devoted wife such as Penelope that wait for her Ulisse, the only man in her life.
Ability in retention and attractiveness are two faces of the same medal for a successfull company.

I will give you a point of view on which you can reflect:

Attractiveness? Included search costs, training costs, a top salary, an immaterial cost of integration ....
Retention? ability in creating new incentives, in giving qualified training, in exploiting experience and knoledge of the company processes ...
