Onboarding — easing new hire into their jobs as quickly and efficiently as possible — is a technique that a growing number of businesses are adopting. But while onboarding programs are becoming increasingly popular, it's also true that many businesses fail to exploit the process to its full potential. That's a shame, because a little time and energy spent helping a worker at the beginning of his or her employment can pay big benefits in terms of job performance and loyalty for many years to come.
