It’s a difficult thing, in the busy work world we all live in, to make sure your people are looked after and appreciated. It’s very easy to take them for granted because you trust them to do their work. I’m not saying you should micromanage them, but showing an interest in them and their work would help them feel like part of the team. Letting other things get in the way creates an issue. One that may lead your best performers to leave for a place where they feel more appreciated.
