It has been observed especially at client facing services that clients are often more favourable towards the personnel serving them rather than the company itself. This is because at such service- centric professions such as management consulting or law, the personal attention is immense. Thus a study was conducted to gauge the differential and it was noticed that with each six months extra being devoted, the chances of the client shifting loyalties to the employee increases by an additional two percent. This is particularly impactful when employees at the service provided either join any competitor or start their own enterprise. Companies are aware of this trend and thus seek employees who can bring with themselves their existing clients.
