It’s dubious whether this person brought their social media personality into the office. And who’s to say that the entire localized team might not share in the same culture? Would be interesting to hear accounts from the coworkers. Certainly it sounds like there was at least one who had the author’s back. Finally, I am unsure whether that is an accurate, or fair, assessment about their particular subculture. Are you operating with additional insight on that subject? From an insider’s perspective, perhaps?
