Previous Updates on the Case

Plaintiffs filed their motion for class certification on October 27, 2017. A public version of the motion is available here. Public versions of Plaintiffs’ expert reports are available here and here. Plaintiffs are currently seeking to unseal most of the evidence in support of their motion and expect more of that material to be publicly available in the coming months. Microsoft’s opposition to the motion for class certification is due on January 5, 2018, and Plaintiffs’ reply is due on February 9, 2018. After that, the Court will issue an order, which typically takes from one to five months. Plaintiffs’ motion seeks certification of a class of female employees who worked in the Engineering or I/T Operations Professions and in stock levels 59-67 from September 16, 2012 to the present.

On October 14, 2016, the district court denied Microsoft’s second motion to dismiss the disparate impact claims in the case. The court also ruled that the statute of limitations for the Washington state law claim extends back to September 16, 2012. Read a copy of the court’s order here.

On March 8, 2016, the district court denied Microsoft’s first motion to dismiss the case.  The court ruled that discovery shall proceed based on Plaintiffs’ current class definition, which includes all current and former female technical professionals employed by Microsoft in the U.S.  The court gave Plaintiffs thirty days to file an amended complaint pleading their disparate impact claim in more detail.  The amended complaint was filed on April 7, 2016.

On September 16, 2015, a gender discrimination class action lawsuit was filed against Microsoft Corporation. The class action, Moussouris v. Microsoft Corporation, was brought by a former female Microsoft technical professional on behalf of herself and all current and former female technical professionals employed by Microsoft in the U.S. On October 27, 2015, an amended complaint was filed, adding current Microsoft employees Holly Muenchow and Dana Piermarini as named plaintiffs, in addition to Ms. Moussouris.

Allegations Of Sex Discrimination In The Workplace By Microsoft

The class action complaint alleges that Microsoft has engaged in systemic and pervasive discrimination against female employees in technical and engineering roles (“female technical employees”) with respect to performance evaluations, pay, promotions, and other terms and conditions of employment. The unchecked gender bias that pervades Microsoft’s corporate culture has resulted in female technical professionals receiving less compensation than similar men, the promotion of men over equally or more qualified women, and less favorable performance evaluation of female technical professionals compared to male peers.

The complaint alleges that the disadvantage to female technical employees in pay and promotion is not isolated or exceptional, but rather the predictable result of Microsoft’s policies and practices and lack of proper accountability measures to ensure fairness, and that Microsoft has implemented these policies and practices despite knowing that they have a long-standing disparate impact on female technical employees.

The complaint further alleges that Microsoft’s continuing policy, pattern, and practice of sex discrimination against female technical employees violates federal and state laws, including Title VII of the Civil Rights Act of 1964 and the Washington Law Against Discrimination.

The proposed class includes women who worked at Microsoft from September 16, 2012 to the present.

Relief Sought in Microsoft Gender Discrimination Lawsuit

The lawsuit seeks back pay as well as monetary damages, including punitive damages, sustained as a result of Microsoft’s unlawful discrimination.

The lawsuit also seeks several orders, including:

  1. An injunction against Microsoft to keep it from engaging in policies, patterns, and/or practices that discriminate against its female technical employees because of their gender or participation in this lawsuit;
  2. An order requiring that Microsoft institute and carry out policies, practices, and programs that provide equal employment opportunities for all employees, regardless of gender, and that it eradicate the effects of its past and present unlawful employment practices;
  3. An order requiring Microsoft to develop and institute accurate and validated standards for evaluating performance, determining pay, and making promotion decisions;
  4. An order appointing a monitor to ensure that Microsoft complies with the injunction provisions of any decree that the Court orders; and
  5. An order restoring the plaintiff and class members to their rightful positions at Microsoft (i.e., reinstatement), or in lieu of reinstatement, an order for front pay benefits.
