Unpopular answer: alcohol. Not while your working hours, of course. When I first came to UK as a tourist, I traveled quite a few European countries and was of high regard towards my English. Bummer: starting from Heathrow border control I could barely understand people and they had to make an effort to understand me. Same at the hotel. So I got to the nearest local pub and was sitting there really having hard reflections on my language skill, when someone approached me and says something like "Hey, mate, why the long face?". I tried to communicate and to my surprise it was easier than before. In a couple hours and few pints I was supporting not just a small talk, but the full fledged political discussion about Putin killing Litvinenko. I read later, that alcohol, to put it simple, breaks our internal barriers. In my case language trouble was caused by such barrier named "I must be good at things". So I was trying to build correct phrases, use articles, tenses and so on. After couple of beers I just throwed all these out of the window and was more interested in listening to my peers and getting my words to them. The same is correct for the work: everyone knows than you are not a native speaker, and no one expects you to use Shakespeare's language. All you need is to get the information from and to your team, no matter accent and other things. If someone will snob you with your language skills - let them be, they probably don't have any other reason to feel themselves superior to you.
