before get the answers:ask yourself:

at workplace,
your "shabby English" is understood? can you understand them, most of times?
do you often chat with people?
do you have lunch and enjoy talking with people?
do you share your little stories with others?
do your share your life exp with others?
do you often have small talks with other?
when people talking, do you reflect actively, or just say "ok." , "yes", "all right"?
...

as a matter of fact, you can get the answer after you think about the questions.

good luck!
