I love the English language and I have a deep fear that this is the final destination for our language; that given demographics it will start to permanently reflect Mandarin translationisms, at least in the workplace. So many code reviews and design docs I deal with now are full of missing articles and tenses. I try to help with corrections but it can honestly start to feel like you're a big jerk in a code review if you're constantly correcting people's English.
It can be done better or worse - some of the best advice I got for teaching ESL was that if someone uses incorrect grammar, to simply repeat the clause with correct grammar and a 'go on?' tone. Immediate, low-friction feedback is one of the best ways to learn, what makes people think you're a jerk is if you call attention to their mistakes.
Of course, that's much easier in conversation than written communication. A good reason to make small talk with your co-workers.
