The playground isn't the only place where you'll run into bullies. Internet bullying has led to suicides. Office bullying is on the rise, and it's a deal-killer no matter what business you're in.

If you think people outgrow bullying behavior just because they get older, think again. Bullies come in all ages, shapes and sizes - and on all rungs of the corporate ladder.

Remarkably, bullying in the workplace is among the leading reasons for employees to seek other employment. Even more remarkably, most don't list bullying as the reason they quit.

Instead, they suffer in silence and take their talents elsewhere.

And suffer they do. Scholars at the Project for Wellness and Work-Life at Arizona State University found that "workplace bullying is linked to a host of physical, psychological, organizational and social costs." Their research indicated that stress is the most predominant health effect associated with bullying in the workplace: "Stress has significant negative effects that are correlated to poor mental health and poor physical health, resulting in an increase in the use of sick days or time off from work."

Can any company afford that?

In a CareerBuilder survey of more than 5,600 full-time employees, 27 percent of workers said they have felt bullied in the workplace. Most of them didn't confront the offender or report the abusive behavior.

What form did the bullying take? Workers gave these examples:

• Comments dismissed or not acknowledged: 43 percent.

• Falsely accused of a mistake: 40 percent.

• Needlessly harsh criticism: 38 percent.

• Forced into doing work that wasn't really part of the job: 38 percent.

• Held to different standards and policies from other workers: 37 percent.

• Made the focus of gossip: 27 percent.

• Yelled at by boss in front of co-workers: 24 percent.

• Belittling comments during meetings: 23 percent.

• Others taking credit for work: 21 percent.

Does any of this sound familiar?

Management is responsible for keeping the workplace free of sexual, racial or other forms of harassment and inappropriate behavior. If an issue is reported, reasonable action should follow.

Unfortunately, sometimes the manager is the bully. If that manager has a manager, the victim needs to go to that level. He or she might be doing the company a huge favor by exposing the reason so many good people in that department are heading for the hills.

Mackay's Moral: If you're being bullied, take the bull by the horns before there's a stampede.
