Most companies spend only one to two weeks on their employee onboarding program, which is a big mistake. Onboarding that is too short leads to poor employee retention, dissatisfaction among employees and even a toxic work environment that can put strain the existing team.
The general consensus among HR professionals is that an onboarding should last at least three months. However, research shows that companies can increase employee retention if they extend the onboarding process throughout an employee's entire first year.
