What is the process of providing workers with training for a completely new job called?

The process of providing workers with training for a completely new job is known as retraining. This involves teaching employees the new skills and knowledge required to perform different tasks that are distinctly different from their previous roles. Retraining is often necessary when new technologies are introduced, when there is a shift in market demand, or when an employee transitions to a different job role within the organization.

In contrast, upskilling refers to enhancing existing skills rather than teaching entirely new ones. Cross-training involves training employees in multiple roles to improve flexibility within the workforce, but it does not imply that the employee is being trained for a completely different job. Orientation training is an initial training process to help new employees understand the organization, its culture, policies, and procedures, rather than equipping them for a new job beyond their initial role. Thus, retraining is the term that best captures the comprehensive training for a completely new job position.
