The Mad Men are not as far behind us as we thought.

The Elephant In The Valley survey polled over 200 senior women in Silicon Valley, and found that 60 percent of them reported unwanted sexual advances at work.

Of that group, 65 percent said these advances were made by higher-ranking colleagues. Another 60 percent of those who had reported an incident were dissatisfied with the response.

An informal survey we ran on Twitter surfaced the same theme: 63 percent said they have experienced harassment in their workplace, according to combined results from two polls taken in June.

Mistreatment of women in the workplace is an economic as well as social problem because companies with women in the C-suite show better financial performance. When women are treated poorly in technology culture, they leave and don’t return to the industry.

Not that financial performance should be the first consideration in efforts to root out sexual harassment in the workplace.

Still, the situation isn’t completely bleak. Our poll about female founders and role models showed the largest proportion of respondents saying they could name at least two or three in the industry.

The existence of role models can contribute to increasing female participation in the workplace.
