One of the more common mistakes in the hiring process is failing to offer vigilant, clear, and supportive onboarding for new hires. Too often, managers celebrate the moment a candidate accepts an offer but forget that onboarding is as important to successful hiring as interviews or reference checks. The effort required to upgrade your onboarding from conventional to best practice is low, but the benefit is enormous. It's been found that employees who go through a structured onboarding process are 58 percent to 69 percent more likely to be with the company after three years than those who don't. Best practice onboarding has three elements: vigilance, transition, and clarity with support.
