Too many companies bet on having a cut-throat, high-pressure, take-no-prisoners culture to drive their financial success.

But a large and growing body of research on positive organizational psychology demonstrates that not only is a cut-throat environment harmful to productivity over time, but that a positive environment will lead to dramatic benefits for employers, employees, and the bottom line.

Although there’s an assumption that stress and pressure push employees to perform more, better, and faster, what cutthroat organizations fail to recognize is the hidden costs incurred.

First, health care expenditures at high-pressure companies are nearly 50% greater than at other organizations. The American Psychological Association estimates that more than $500 billion is siphoned off from the U.S. economy because of workplace stress, and 550 million workdays are lost each year due to stress on the job. Sixty percent to 80% of workplace accidents are attributed to stress, and it’s estimated that more than 80% of doctor visits are due to stress. Workplace stress has been linked to health problems ranging from metabolic syndrome to cardiovascular disease and mortality.

The stress of belonging to hierarchies itself is linked to disease and death. One study showed that, the lower someone’s rank in a hierarchy, the higher their chances of cardiovascular disease and death from heart attacks. In a large-scale study of over 3,000 employees conducted by Anna Nyberg at the Karolinska Institute, results showed a strong link between leadership behavior and heart disease in employees. Stress-producing bosses are literally bad for the heart.
