The book protects the interests of everyone, who needs INTERPRETATION BUT is unfamiliar with the target foreign languages. It offers the non-Foreign language speakers the keys to unlock three mysteries: + How to evaluate the foreign language skills of an employee; a language assistant; or an interpreter despite the lack of knowledge of that language, + How to manage an interpretation session without knowing the target non-English languages, and + How to reach the primary goal of a session utilizing interpretation services without studying the necessary foreign languages. No matter what experience the readers have or what field they are in, this "Errors Proof Jacket" will protect them against out-of-control influence by inaccurate interpretations.
