Whether it’s a standoffish coworker or an arrogant boss, incivility at the office doesn’t just affect the moods of a few employees; it hurts an entire company.

Consider these statistics: 12 percent of all employees say they’ve left jobs because they were treated badly. Fortune 1000 executives spend roughly seven weeks per year resolving employee conflicts. And an astonishing 95 percent of Americans say they’ve experienced rudeness at work.

Christine Pearson and Christine Porath examine the devastating toll that bad behavior can have on otherwise well-functioning companies. Combining their own scientific research with stories from fields as diverse as criminology, education, and psychology, they show how to spot the roots of incivility, rip them out, and create a culture of respect. They urge managers to stop making excuses, set a zero-tolerance policy, and lead by example.

Bestsellers like The No Asshole Rule and The Power of Nice have shown the hunger for more civility at work; now The Cost of Bad Behavior shows exactly what to do about it.
