Onboarding is the process of introducing new employees to a company, its culture, policies, responsibilities, and work environment. It usually includes training, orientation sessions, paperwork, and guidance from managers or team members. Effective onboarding helps employees understand their roles faster and feel comfortable in the workplace. It is important because it improves productivity, boosts confidence, reduces confusion, and increases employee retention. A strong onboarding process also helps new hires build relationships with coworkers, adapt to company expectations, and contribute more successfully to business goals from the beginning of their employment.
