According to a recent CareerBuilder survey, perceptions of unequal pay and career advancement opportunities are increasing in the workplace.Thirty-eight percent of female workers said they feel they are paid less than their male colleagues in the same roles that also have the same skills and experience, a marked increase over 2008’s 34 percent and 2003’s 31 percent during a similar survey.Additionally, 39 percent of women feel men have more opportunities to advance in their career, up from 26 percent in 2008.The perceptions seem to be rooted in fact. During a salary comparison, 45 percent of men surveyed reported they make $50,000 or more, compared to 24 percent of women. Ten percent of men make $100,000 or more, compared to just 3 percent of women. Alternatively, 40 percent of women reported their income at $35,000 or less compared to 24 percent of men.In regards to advancement, 30 percent of men surveyed said they hold a management position compared to 21 percent of women.“While many companies are working toward greater equality in all measures of the workplace, a significant disparity still exists,” said Rosemary Haefner, vice president of human resources at CareerBuilder. “Workers in general are more aware of average compensation levels. They are also more vocal about shortcomings they believe exist when it comes to their pay and title, especially coming off of a recession when workloads and hours largely increased.”More than one-third of women (35 percent) attributed the disparity in pay and career advancement to the fact that they don’t rub elbows or schmooze with management as much as men. Nearly a quarter simply felt management showed favoritism to the opposite sex.When asked what annoyed them most about the opposite sex in the office, men said women tend to gossip or become too emotional or sensitive. Women said men can be too arrogant, make inappropriate comments and don’t take female co-workers seriously.
