Onboarding is a term used to describe the welcoming of a new employee in their new team. In most cases, it refers to the employee's first few days, possibly also their training, plus handling of all formal and informal details connected with the start of their employment. This article will provide a checklist of what should be provided to the new worker on their first day and what that day should look like. We will focus here only on informal aspects and omit such matters as signing a contract or dealing with tax forms.
