The real problem is that business English is merely a marketing system. It's purpose is not to teach you about business in English, its purpose is to make you speak better English. The only whiff of business is the office-based examples. How can someone who needs to learn English from scratch expect to start with, say business English for beginners (they do sell these)? It's like trying to run before you can walk. All language learning should be based on a firm and solid base without a narrow focus on one or another aspect. If you have learnt English well and can successful understand and enjoy the majority of things you may watch or hear, you will have no problem learning any new vocab necessary to your specific profession, but what good is writing the perfect fax or e-mail when you can't understand shit?
Now, I’ve taught business English and this, my Russian friends, should be your first warning of the retarded English teachers operating out there. Both the English and Russian teachers operating are not businessmen and most, at least financially, are not successful life examples that one would want to imitate. So, does your business English teacher actually have the first clue about business? Are they businessmen? No, they’re not, so why pay them money to do something you could be doing alone with a book (most English teaching text books have answers in them).
As for the English-speaker reader
You may think this bears no relevance to you, but if you do plan on teaching here, it will annoy you too. I’ve had enough of complete novices asking for business English when they can’t even string two freaking words together. The smaller companies can sometimes be quite unprofessional so it’s really important you choose the right one. I’ll make a separate post about working with Russians and will list some of the bad experiences I’ve had. But before i end this, i want any Russian reading it to know, this post is to try and help you save money and improve your English, i have no motif here other than to make your learning time more efficient.
