Are you remembering the importance of thanking your colleagues on a regular basis? Because the following story makes me feel a little delinquent when it comes to expressing my 'thanks' to people! The CEO of Belfor Holdings, Inc., Sheldon Yellen, writes (and yes, by hand) birthday cards to each of his 9,200 employees as a way to say thank you.

Yellen has written a birthday thank you card to every employee, every year, since 1985. And if that isn't enough, he also sends regular thank you notes, anniversary cards and get well cards for employees' children when they are sick. Many of his managers have embraced the habit with their own teams, and according to Yellen, the practice has created a more gracious and compassionate workplace culture.
