Final answer:
An employee hired for less than three business days must present two original documents, one for identity and one for employment authorization, as required by the Immigration Reform and Control Act of 1986 and facilitated through the I-9 form.
Step-by-step explanation:
The question pertains to the requirements set by the Immigration Reform and Control Act of 1986 regarding the verification of an employee's legal right to work in the United States. Specifically, it asks how many original documents an employee who is hired for less than three business days must present to show their identity and employment authorization.
According to the regulations, the employee is required to present two documents; one that confirms their identity and another that verifies their employment authorization, prior to commencing employment, regardless of the duration of their employment term.
This process is facilitated through the completion of the I-9 form, which all employees, regardless of the length of employment, must complete.
