This is the only book that describes the specifics of French management (and society) in easy to understand detail.

Of course, it helps if you're at least bilingual, as French phrases are intermingled everywhere in the book. Of course, they always provide translations, but it can help scare non-French speaking people away (and if that is the case, don't buy this book and don't do business with the French).

If you're interested in understanding the French, especially the businesspersons, , this is varmly recommended.
