I am a manager in an environment that has a history of employing many non-English speaking minorities. They are for the most part very hard working and productive and have presented assumedly valid green cards, soc. sec numbers and/or work visas. Recently I have come into a situation where my home office has rejected a few individuals paperwork, claimed they are completely invalid, that they are not legally employable in this country and that these persons must no longer be employed by the company. A few days later my boss had rehired these persons under different names and numbers (in addition, this being the third sets of invalid documentation). Am I at any legal risk because I KNOW the individuals I see before me cannot legally work in this country, and my superiors are allowing it to happen? Have my superiors broken any laws, and have I because of association?
