So, with ever decreasing focus time and constant meetings where most of time we do not have actionable output. yeah, this is truth of corporate. I really feel, when we just say ‘Hi’, “Hello”, “Greetings of the day” “how are you” in professional chat like skype or teams and wait for other person to respond without full message or intention in chat, we are disrespecting someone else time. If you really feel and value your and someone’s time, Please send full message along with intention of conversation, other person can revert with necessary response, than just one more line of ‘hello”, also this will give opportunity to other person to find appropriate answer/response to your query if he do not have handy.
