Most of us sign our work emails with ‘thanks,' but according to author Janice Kaplan, who penned ‘The Gratitude Diaries,’ there’s a conspicuous lack of genuine thanks in the workplace. This is a pity, because it turns out gratitude is profoundly motivating—maybe even more motivating than money! In a new study, 81 percent of people said they’d work harder for an appreciative boss, but only 10 percent said they showed their colleagues gratitude on a regular basis. Conversely, financial incentives provide temporary fuel, but once they’re achieved, employee satisfaction goes back to baseline. The bottom line? Whether you’re a worker bee or a boss, don't be afraid to show gratitude at the office. It might get you more than just appreciation. Does your office have a culture of gratitude, or platitudes? Sound off in the comments.
