Expressing thanks in the workplace involves thoughtfulness and skill. Based on a gratitude journaling exercise over the course of a month by 58 American professionals (Study 1) and a survey of over 1,200 American professionals (Study 2), this research demonstrates the many written and spoken ways in which professionals value receiving thanks in low-effort, high-effort, minor-accomplishment, and major-accomplishment situations. The research suggests gratitude expressions can be interpreted through media synchronicity theory and social comparison theory. A variety of training and teaching approaches are offered.
