Unhappiness can be expensive. According to Gallup's 2018 State of the Global Workplace report, 85% of employees are not engaged at work, and it's costing our economy approximately $7 trillion in lost productivity each year.

While it's important for business leaders to take action, employees are also encouraged to seek out their own ways of boosting satisfaction at work. Why? A cheery disposition — and not a bigger paycheck — can actually make you better at your job and less likely to quit.
