Thomas and Ruth Roy of Wellcat Holidays created the observance in 1997 as part of their catalog of unofficial holidays designed to add humor and reflection to everyday life.
The Science of Workplace Happiness
By the late twentieth century, organizational psychologists had built an entire field around engagement. Gallup launched its Q12 employee engagement survey in 1999, creating the first widely used yardstick for measuring how connected people felt to their work. The data it generated showed a consistent pattern: teams with higher engagement had lower turnover and better performance.
A 2013 study at the University of Warwick gave the connection a specific number. Researchers found that happy workers were roughly 12 percent more productive than their unhappy counterparts. That gap, applied across an entire company, represented a measurable competitive advantage.
