Today's work force is more diverse, and women are no exception to this trend. In fact, women are filling more senior leadership roles than they were just 10 years ago, which can be attributed to a shift in attitude in the workplace, says Eileen Habelow, senior vice president of organizational development of Randstad, a provider of human resources services.

In the past, there was a stigma attached to women in senior leadership roles, but this is no longer the case, Habelow says. Companies are even finding that organizations with women in senior leadership roles tend to have a competitive advantage. With women taking on those roles, there is greater diversity at the top, leading to better management among a varied work force.

"With a diverse pool of leaders, an employer can be more effective at leading a diverse pool of workers," Habelow says. "The more you diversify at the leadership level, the more effective you'll be at leading a diverse work force pool."
