NEW YORK -- The Google engineer who wrote a highly controversial internal memo about gender differences that'ssays he's been fired -- and that he's not going to take it lying down.
James Damore's memo, which claims biological factors contribute to gender inequality in the tech sector, sparked a quick rebuttal from Google after it circulated widely online.
Google CEO Sundar Pichai denounced the memo in an email Monday for "advancing harmful gender stereotypes" and said he was cutting short a vacation to hold a town hall with staff on Thursday.
Damore's widely shared memo, titled "Google's Ideological Echo Chamber," criticized Google for pushing mentoring and diversity programs and for "alienating conservatives."
Google's just-hired head of diversity, Danielle Brown, responded earlier with her own memo, saying Google is "unequivocal in our belief that diversity and inclusion are critical to our success." She said change is hard and "often uncomfortable."
In a statement to CBS News early Tuesday, Damore said he had been "wrongfully terminated" for what Google told him was "perpetuating gender stereotypes."
"As far as I know," Damlore said, "I have a legal right to express my concerns about the terms and conditions of my working environment and to bring up potentially illegal behavior, which is what my document does. Before being fired, I submitted a charge to the National Labor Relations Board about how Google's upper management is misrepresenting and shaming me in order to silence my complaints. It's illegal to retaliate against a NLRB charge.
"I think what they did was illegal and I'm currently exploring all possible legal remedies," Damore said.
The battling messages come as Silicon Valley grapples with accusations of sexism and discrimination.
Google is in the midst of a Department of Labor investigation into whether it pays women less than men, while Uber's CEO recently lost his job amid accusations of widespread sexual harassment and discrimination.
Leading tech companies, including Google, Facebook and Uber, have said they are trying to improve hiring and working conditions for women. But diversity numbers are barely changing.
Damore's memo, which gained attention online over the weekend, begins by saying that only honest discussion will address a lack of equity. But it also asserts that women "prefer jobs in social and artistic areas" while more men "may like coding because it requires systemizing."
The memo, which was shared on the tech blog Gizmodo, says biological differences between men and women are the reason "we don't have 50 percent representation of women in tech and leadership."
While the engineer's views were broadly and publicly criticized online, they echo the 2005 statements by then-Harvard President Lawrence Summers, who said the reason there are fewer female scientists at top universities is in part due to "innate" gender differences.
Brande Stellings, senior vice president of advisory services for Catalyst, a nonprofit advocacy group for women in the workplace, said the engineer's viewpoints show "how ingrained, entrenched and harmful gender-based stereotypes truly are."
"It's much easier for some to point to 'innate biological differences' than to confront the unconscious biases and obstacles that get in the way of a level playing field," Stellings wrote in an email.
Google, like other tech companies, has far fewer women than men in technology and leadership positions. Fifty-six percent of its workers are white and 35 percent are Asian, while Hispanic and Black employees make up 4 percent and 2 percent of its workforce, respectively, according to the company's latest diversity report.
Tech companies say they are trying, by reaching out to and interviewing a broader range of job candidates, by offering coding classes, internships and mentorship programs and by holding mandatory "unconscious bias" training sessions for existing employees.
But, as the employee memo shows, not everyone at Google is happy with this.
