Nearly one-third of women said they feel discriminated against or treated unfairly based on their gender at least once a week.

Twenty-five percent of female workers have experienced discrimination or unfair treatment in the workplace, and 17 percent said they have felt sexually harassed by a fellow employee or manager, according to a nationwide survey conducted by Harris Interactive. Of those who reported the incident to their employers, the majority said the offender was not held accountable.

The study, "Diversity in the Workplace," was designed to gauge the frequency, severity and occasion for perceptions of discrimination or unfair treatment and how diversity impacts hiring, compensation and career advancement. It focused on seven diverse segments including women, Asians, African Americans, Hispanics, workers with disabilities, mature workers age 50 or older and Gay/Lesbian/Bisexual/Transgender workers.

"As the female labor force has steadily climbed over the past quarter-century, employers have come a considerable way in implementing fair and equal workplace practices," said Rosemary Haefner, vice president of Human Resources at CareerBuilder.com. "Nevertheless, this study indicates that there is still much room for improvement. Nearly one-third of women said they feel discriminated against or treated unfairly based on their gender at least once a week."

"Despite the strides women and other diverse groups have made in the workplace, there is still a void at the top," said Nina Ramsey, senior vice president of Human Resources at Kelly Services. "Forty percent of all workers -- both diverse and non-diverse -- say there is an absence of diverse workers in management in their workplace. In order for an organization to evolve, their hiring, leadership development and succession practices need to evolve and include workers of all backgrounds."

Severity and Frequency of Discrimination or Unfair Treatment in the Workplace

Fourteen percent of female workers categorize the discrimination or unfair treatment they experienced at work as severe while 61 percent described it as moderate. Thirty-one percent of female workers said they experience discrimination or unfair treatment at least once a week. Twenty-six percent said once a month and 34 percent said it happens occasionally (defined as one to three times per year).

Reporting of Discrimination or Unfair Treatment

Unfortunately, much of the discrimination or unfair treatment goes unaddressed.

Seventy-two percent of female workers said they didn't think reporting the incident would make a difference while 46 percent feared being labeled as a trouble-maker and 34 percent feared losing their jobs.

Most of the female workers who reported discrimination or unfair treatment did so by bringing it to the attention of their direct supervisor (34 percent). Another 26 percent reported it to Human Resources while 18 percent reported it to someone in senior management. The majority of workers who reported the incident (61 percent) said they didn't think their claim was taken seriously and, in 69 percent of the cases, the offender was not held accountable. Only 3 percent of female workers took legal action against their employer.

Sexual Harassment

Seventeen percent of women said they have felt sexually harassed at the office. Seven percent said the source of harassment was by a peer, 8 percent pointed to their supervisor and two percent pointed to senior management. Fifty-nine percent did not report the incident. Of those who did report the incident, one-in-four said it was never addressed by the authority figure they consulted at work and 27 percent said the offender was not held accountable. Only 9 percent said the offender was fired.

Twenty-one percent of all workers -- both diverse and non-diverse -- said they have witnessed discrimination or unfair treatment of a co-worker based on their diverse background.

Hispanics
Another recent poll by Harris Interactive found that twenty-nine percent of Hispanic workers have experienced discrimination or unfair treatment in the workplace. Of those who reported the discrimination or unfair treatment to their employers, 77 percent said the offender was not held accountable.

"Hispanic workers are among the fastest growing segments of the U.S. labor force," said Jesse Caballero, Senior Career Advisor for empleosCB.com, a subsidiary of CareerBuilder.com. "They are also among the two groups reporting the highest levels of severe discrimination in the workplace. Fifteen percent said they have been addressed with a racial slur at work. Roughly one-in-four feel they are paid less and have fewer career advancement opportunities compared to their Caucasian counterparts."

Severity and Frequency of Discrimination or Unfair Treatment in the Workplace

Of the segments surveyed, Hispanic workers were among the most likely to categorize the discrimination or unfair treatment as severe at 26 percent. Twenty-nine percent of Hispanic workers said they experience discrimination or unfair treatment at least once a week. Eighteen percent said once a month and 31 percent say it happens occasionally (defined as one to three times per year).

Fifty-five percent of Hispanic workers who experienced discrimination or unfair treatment said they did not report the incident. Sixty percent of Hispanic workers said they didn't think reporting the incident would make a difference while 33 percent feared being labeled as a trouble-maker and 17 percent feared losing their jobs.

The majority of Hispanic workers who reported discrimination or unfair treatment did so by bringing it to the attention of their direct supervisor (24 percent). Another 22 percent reported it to someone in senior management while 13 percent reported it to Human Resources.

Twelve percent of Hispanic workers took legal action against their employer, the highest of all diverse groups surveyed.

"Creating and enforcing a healthy, balanced, diverse work culture starts at the top. This study reinforces the relative scarcity of diverse workers in management in most organizations," said Nina Ramsey, senior vice president of Human Resources at Kelly Services. "We can hope that the environment for Hispanics and other diverse workers will steadily improve as hiring, leadership development and succession practices evolve and include workers of all backgrounds."
