Thanksgiving is all about showing gratitude, but sometimes we forget to do it with some of the people we see every day: our co-workers. Sara Algoe, who studies social interactions at the University of North Carolina at Chapel Hill and is director of the Love Consortium, gives us a crash course in the best practices for showing appreciation and explains why saying thanks is as important for the person giving it as it is for the person receiving it. And we hear from Jacob Coite, who has made an art out of showing appreciation to the people he works with.  Send us your stories about work and careers!
