Being [on the same page]

"ジョンさん、この会社に、コミュニケーションは一番大切です。「John, in our company, communication is the most important.」 It's vital that everyone is on the same page. All team members need to know what the others are doing. That's how an effective organziation operates. Do you understand?" ask my manager..

"はい、はい、はい。分かりました。 [Yeah, yeah, I got it.]" I replied grudingly (incidentally, this was pretty rude... saying Hai multiple times in succession usually indicates annoyance... but who cares... I'm a GAIJIN.) "Anything else before we conclude?" I asked.

His VERY NEXT SENTENCE was, "Yes there is, I don't want the others to know about the next item. Please keep this conversation a secret."
