In Company Second Edition is a fast-paced, four-level Business English course for professional adults who need to communicate in everyday business situations.
I actively dislike this book. I know that many people think business students don't need grammar, which is probably why this book marginalizes grammar. But, in my opinion, at Pre-Intermediate level some basic grammar needs to be taught. Otherwise your students end up speaking fluently, but no one will understand them because of the bad grammar they use. In addition, the listening tasks are horrible. There are usually no gist tasks, only detailed tasks, and in the gap-fill tasks there are usually 4-5 consecutive gaps per sentence to be filled in, which would be almost impossible to do even for higher-level students. In sum, don't waste your money on this...
