An onboarding checklist is a tool used by organizations to ensure that new employees are properly integrated into the company and their roles. It is designed to go beyond the first day of orientation and includes many steps involving several departments. The checklist ensures that the organization does not miss any crucial steps in the onboarding process, which can help to retain employees for longer. The checklist includes items to be completed on the first day, the first week, the first month, and beyond, and is intended to provide employees with the encouragement and support they need to become productive and engaged in their roles.
