Meanwhile, Google's HR department allegedly accused a conservative employee of "inciting violence" after he stated that he would teach traditional gender roles to his children.
The engineer who was sacked by Google after he criticized its diversity policies - he issued a memo saying women land fewer tech jobs than men because of biological differences - sued his ex-employer, alleging that he and others at the internet giant were harassed over their conservative political views.
James Damore was fired from his engineering job at Google past year after he wrote a memo that criticized the company's diversity efforts and argued that the low number of women in engineering positions was a result of biological differences.
The lawsuit was filed Monday in Santa Clara County Superior Court.
Damore's fellow plaintiff in the class action is another Google employee, a former software engineer named David Gudeman. Included in the lengthy post were comments that men and women have different interests and abilities, affecting diversity in tech jobs and pay gaps.
Danielle Brown, at that time the Google vice president of diversity, responded to the document in a memo, writing that the document "advanced incorrect assumptions about gender" and that "it's not a viewpoint that I or this company endorses, promotes or encourages".
"Google's under-leveling of women not only resulted in Google paying them lower base salaries than if they had been properly leveled, but also resulted in Google paying them smaller bonuses and fewer stock units and options than if Google had placed them in the proper level", that lawsuit says, according to Associated Press. Damore, who also filed a complaint with the National Labor Relations Board, appeared to embrace his rising political visibility, posing in a T-shirt with the word "Goolag" written in a multicolored style that mimicked Google's familiar logo.
After he was sacked, he became a cult hero of the political right.
