Professor Alex Edmans of The Wharton School of the University of Pennsylvania discovered that businesses with high levels of employee satisfaction perform better than those without. Research from the University of Warwick says happiness makes people 12 percent more productive.

This essentially means that 87 percent of employees have no passion for their work, lack motivation to get the job done and are unhappy.
