Executive Positions: Women More Responible Than Men?

What a man can do, a woman can do better.

According to a Duke University paper, females in leadership positions are regarded as better at the job.

The study reveals that women are seen by employees as more competent and relationship oriented. It’s an ironic development. Women have to work harder and face more obstacles than their male counterparts, which also makes them substantially more effective and respected once they reach executive positions.

How true is this?
