The letter sent to Whitman by the SSA regarding the maid’s SSN specifically states: “This letter … is not a basis, in and of itself, for you to take any adverse actions against the employee … Any employer that uses the information in this letter to justify taking adverse action against an employee may violate state or federal law and be subject to legal consequences.”
AND … While employers are required to complete a Form I-9 attesting that the employee provided “facially valid” proof of identity and eligibility to work, It is ILLEGAL to arbitrarily reject valid or valid-looking documents, or to demand more proof than the law requires. That constitutes discrimination based on immigration status, national origin, etc.
