Microsoft Gender Bias Case Seeks Class Action Status for 8,600 New Plaintiffs

With co-counsel, Lieff Cabraser represents three female current and former tech professionals suing Microsoft Corp. for gender discrimination who are seeking class action status for their suit to bring in an additional 8,630 female Microsoft workers who have been employed by the company since 2012.

The women claim that the giant software maker maintained “an abusive, toxic ‘boy’s club’ atmosphere, where women are ignored abused, or degraded.” Microsoft is also accused of discriminating against female workers via a “stack ranking” employee evaluation process, which plaintiffs argue has a disparate and negative impact on women. The complaint also notes many instances of male co-workers discounting their female counterparts during meetings and sexually harassing them.

The complaint alleges that Microsoft is in violation of Title VII of the Civil Rights Act of 1964 and the Washington State Law Against Discrimination through actions leading to lesser pay and fewer promotions of female employees than their male counterparts.

As reported by Bloomberg News, “the women said their expert consultants have determined that discrimination at the Redmond, Washington-based company cost female employees more than 500 promotions and $100 million to $238 million in pay, according to Oct. 27 court filings.”

The case is Moussouris v. Microsoft Corp., 2:15-cv-01483, U.S. District Court, Western District of Washington (Seattle).
