Can you elaborate? I hear this line of thinking a lot, but never explained fully. In particular, what about being in same office helps with unproductive ICs? E. G. you mention tickets - it's not by being in the office that I will notice tickets aging or not being tackled efficiently. Fully recognizing the slacking instinct, I don't see being in office addressing it effectively. You don't stare at any given person's screen 8hrs a day.

(other issues such as social and emotional preferences are also valid but I feel separate and may hash out either way).
