Every language has a word for "thanks." It's one of the few concepts that works in a hut in Bali, a London skyscraper or a mini-mart in Peoria.

In the U.S. (in November) and Canada (in October), we have actual paid-time-off days of "thanks." And while many of us spend these Thanksgiving days expressing gratitude for our families, friends, health or prosperity, what about thanking the people who make your business possible: Your team.

By now there's enough statistical evidence that recognition done right plays a critical role in engaging employees and creating high-performance cultures. Our research shows it also creates enhanced feelings of trust and communication in employees. But it's hard to benefit from the impact of gratitude if you don't do it.

No one knows this better than Kirt Walker, president and chief operating officer of Nationwide Financial in Columbus, Ohio. We were working with Kirt and his amazing leadership team at meeting last week when he issued this challenge: "It's Thanksgiving. Make sure you thank your people."

He then gave them a very specific way he wanted them to accomplish the task: He asked them to write handwritten notes to every direct report, expressing specifically what that employee has done to help the organization thrive. And he wanted them delivered before Thanksgiving Day.

Kirt promised he was going to do it himself. We love it when leaders lead by example.

As Kirt knows, great service will only happen if we keep our employees engaged and focused. And a handwritten note costs almost nothing, but can be a very personal, very powerful way to convey gratitude. It is a warm conversation that is all about you, doesn't beep at you, distract you, or pull you away to do something else.

Letters and notes we've received have found their way into our journals and onto the walls around our desks. They are constant reminders of the people we work with who have become more than associates, they are now my friends. Chester's favorite note came from a colleague--Mike Goodson--who knew he was struggling. After telling Chester specifically how he thought he added value to the world, he summed up with a few lines we'll never forget: "Chester, you aren't just great. In the pantheon of greatness you are the greatest. You, my friend, are Spartacus." Chester laughed, admittedly choked up a little, and the handwritten note is still hanging prominently on his wall years later.

Today, we send a lot of notes, not only to work associates but to family and friends too. Every Sunday Chester says he writes a note to each of his two boys, Brinden and Garrett, who are away from home. He tells them how much he loves and appreciate them, and lets them know they are never far from his thoughts. Once in a while he does get a letter back (because he gave them stationery for Christmas last year, and stamps). One of his favorite notes was from 21-year-old Brinden who said when he gets his dad's letters he doesn't always open them right away, but often saves them for a day when things have been tough in his incomprehensible (to us) chemical engineering classes. As Brinden said, "I know that after I read a letter from my dad, I will feel better about myself."

Whether in our personal or public lives, specific and sincere notes can validate the ones we count on the most, those we care about. It takes so little time and the return far outweighs the effort.

So, wherever you live on this planet, why not use November as your month of thanks? Take a moment to look around you. Give thanks to your team members, your employees, your clients. Send a note of thanks to your leader for those paychecks that keep coming or the assignments and the trust he or she gives you. Send thanks to the network of professional relationships you've built in your industry. Giving "thanks" has never been more appropriate. And don't forget friends and family too.

Take this opportunity to say thanks and your gratitude will spread like melted butter on warm yams. Don't do it and you'll look like a turkey.
