The Girls in Tech nonprofit group’s recent poll found that 66 percent of tech-employed women plan to vote for Hillary Clinton, while 3 percent plan to vote for Trump. A surprising large number — 30 percent — don’t plan to vote for either one of the U.S. presidential candidates.

The survey is based on a survey of 582 women working in the U.S. tech sector, and it’s part of the group’s first quarterly survey on the State of Women in Technology.

Seventy-seven percent feel that a Trump presidency would be damaging for women in the workplace, while only 7 percent felt a Clinton presidency would be damaging.

Aside from the presidential campaign, the survey had other data related to women in the workplace. For instance, 81 percent felt they have experienced gender discrimination.

About 64 percent of the women said they felt that Clinton has been judged more harshly than her male predecessors. And 54 percent of women feel that they have been sexually harassed or experienced a hostile work environment. The same number, 54 percent, said they felt they have been passed over for a promotion because of their gender.

Of those who knew about the Ellen Pao gender discrimination lawsuit against Kleiner Perkins Caufield & Byers, 59 percent hoped that Pao would win her case (she lost), while 37 percent were neutral. Ninety-one percent felt workplace conditions have improved for women in the last five years, while 8 percent felt it has gotten worse.

And 55 percent of women in a relationship with a man made more money than their counterparts.

“Women working in technology have come a long way in increasing our numbers in boardrooms and in technical positions,” said Adriana Gascoigne, CEO and founder of Girls in Tech, in a statement. “This survey shows that there’s still much work to be done, but as a group, we have a strong and powerful voice.”

San Francisco-based Girls in Tech has multiple chapters around the world, and it has 50,000 members. Its aim is to promote women and girls in the tech industry. The survey was conducted last week.
