When a organization has carefully searched for and managed to hire the PERFECT candidate, there is a delicate time period (1 to 6 months from date of hire depending on the position) where that person will either prove to be a great hire, falter or have left.
Recent US data shows half of all hourly workers leave new jobs in the first 4 months and half of senior outside hires fail within 18 months.
Clearly this is costly to an organization. By implementing a robust onboarding program, the odds of success increase exponentially. Onboarding helps new hires adjust to the social and performance aspects of their jobs so they can quickly become productive, contributing members of the organization and feel at home.
