How would you feel if you sent an email to a colleague asking for his opinion and days have passed and yet you haven't received a reply? Perhaps, you too would wonder what went wrong. You become concerned about whether you have offended that person because you didn't get a reply. Maybe you also wondered how you would interact with that person when you see them but yet to receive a reply to your email. Your interaction with your colleagues says a lot about how successful workplace communication is (or not).
