Should people continue working from home (or from anywhere) after lock-downs and social distancing are no longer necessary, the leadership pains so many complain about are just going to get more severe.
Little communication and transparency, lack of empathy, difficulties in sharing a common vision, finding ways to work together on problems rather than distributing solutions. All of this is going to feel even worst when you do not have the aid of common spaces, shared coffee breaks, chit chats with colleagues and informal conversations.
The world is going to need many better leaders.
