"A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples if you love one another.” John 13:34-35
Taking care of your people is one of the guiding principles of every US Marine Corps officer. If you take care of your people, then your people will take care of you. If you do not take care of your people, your people will not take care of you. This means that you need to know your people like a good shepherd knows his flock of sheep. This means that you need to know the good, the bad, and the ugly of your people. You also need to know of some of the challenges that your direct reports are dealing with outside of work, especially if they are affecting your people's performance at work. Most people cannot just check their problems at the door when they come to work in the morning.
