I have been teaching English to business professionals for 6 years, but have just started my own company. I am familiar with many business English books, but they all seem to follow a format that leaves half the book sort of useless for many of my classes.
My current students are managers of production facilities. They don't need anything that deals with sales, negotiation, marketing or finance. I'd really like to find something a little more specific to production/international distribution/suppliers, while still covering all the listening, reading, speaking and reading basics. The students are in two groups: pre-intermediate and elementary.
All help greatly appreciated!
