Want that raise? YouTube's CEO has some advice for women

As the gender pay gap remains stubbornly wide, YouTube's CEO has some tips for her fellow women in tech.

"Whether it's salary or a promotion or a job, I think it's important for women to ask for what they think they deserve," said Susan Wojcicki at the Grace Hopper Celebration of Women in Computing in Houston on Thursday.

Only by asking will women find out whether or not it is possible. She stressed how important it is for women to be their own advocates and not feel guilty about it. It's difficult for a colleague to be an advocate for others, if they are not their own advocates.

In remarks before a packed audience of mostly women, Wojcicki also stressed the importance of getting more women in tech. Women make up just a quarter of computer and math occupations, according to data from the Bureau of Labor Statistics.

In part, misconceptions about computer science, including that it's boring and girls would not be good at it, are driving this gender imbalance in interest in the topic, she said.

"Unless we make computer science a priority, we risk making gender, class and racial disparities worse as jobs flow to those with a computer science background," Wojcicki said.
