...on bad english

I am English teacher in Australia, and I have taught students including some from Phillipines English, as their second language. There is a difference between English as it is spoken(colloquial), and English as it is written. Written English which is often in business communication must be more correct in the ways words are used, and much more strict with grammar rules and sentence structure. This is probably what your employer means.Many students can speak English well, but need practice in using it in writing. There is not much difference in American/Australian/British English, except for some words that are more familiar in one country and not the other, or may mean something different in one country and not the other. American style English is known in every country because of American television and movies. in my experience the spoken language in any country has less rules,less formal and easy to speak and be understood after you have used it for a while. the written language can be harder to learn, because to be effective with it, you need to follow strict rules. it can take months or years of practice, and difficult to learn from a book, without a teacher or someone to guide you through it, and more importantly practise it. some people mainly learn the language by speaking it, others by reading and writing about it in a classroom.This might explain some of the differences between good and bad zenglish.

Practice makes perfect as they say. Find other people in your area who also speak english...or look for a class to take. I think actually USING the language by speaking it helps out much more than just reading manual, particularly with out someone to guide you on proper grammar and pronunciation. Though also, using a site like mylot can also connect you with many people who speak english as a first language and can give you correction and guidance if you ask.

I had subscribed to a newsletter from UK in the past and learned the style of english there albeit just slightly. If you can do the same, you will start to learn more about UK english.
