“4. Give recognition and show appreciation. “The deepest principle of human nature is the craving to be appreciated,” wrote William James, the father of American psychology. It is impossible to be motivated and do great work if you don’t feel that somebody cares and appreciates what you do. Studies have shown that for people to be happy and productive at work, they need to experience positive interactions (appreciation, praise) vs. negative (reprimands, criticism) with their manager in a ratio of at least 3:1. (Watch out: For a marriage to work, you actually need a 5:1 ratio!!) So make it a simple habit to thank people each and every day — and that includes using the word generously in emails to your team. The way people want to receive recognition varies greatly: public vs. private, material vs. immaterial, from peers vs. from superiors, etc. Great managers test different approaches and observe reactions until they find the triggers that work best with each of their people. At MOM’s Organic Market, managers will sometimes publicly recognize employees who have performed well, but CEO Scott Nash has often found that one-on-one comments are most effective.”
