Q. Morales, who speaks only English owns and operates a large warehouse? Most of his workers speak only English, and he requires which all of his workers speak English and which all communication in the workplace, which involves the performance of any job, be done in English. A number of workers whose primary language is not English complain about the policy on the grounds which they can converse in their native languages and still get the job done. If these workers bring a claim of national origin discrimination on the basis of this policy, illustrate what is Morales' best defence? Elucidate.
