The three plaintiffs held different positions while at Google: one was a software engineer, one was a communications specialist, and one was a manager who worked in various roles.
Kelly Dermody, a lawyer for the women said that "While Google has been an industry-leading tech innovator, its treatment of female employees has not entered the 21st century". The complaint also alleged Google consistently assigned women to "lower tiers" or "job ladders" with lower compensation and fewer opportunities for promotion than their male counterparts.
Finberg stated that the case brought against Google would rely heavily on testimony from the U.S. Department of Labor's hearings which showed, "statistically significant (compensation) disparities adverse to women across the board". The analysis revealed a difference of 6-7 standard deviations between pay for men and women in nearly every job classification in 2015; that is quite a large difference of pay simply based on gender.More news: Behind-The-Scenes Pics Show How Disney World Prepared For Hurricane Irma
If it goes to court, the class action lawsuit will grow to cover all of Google's women employees over the past four years in what would be a costly penalty for the Silicon Valley giant.
In an exclusive interview with the Guardian, Ellis said the gender pay gap is a deeply ingrained problem at Google, and while "lip service" has been paid by companies that claim to be committed to combating pay disparities, the problem "hasn't really changed".More news: Danica Patrick seeking new racing team, could consider retirement
"The net result of this systemic discrimination is that Google pays women less than men for comparable work".
"We disagree with the central allegations", Google spokeswoman Gina Scigliano, said in a statement to CNN Tech.
This comes at a time when there has been much talk about the way women employees are paid and discriminated against, as well as about work environments not being diverse enough.
The suit seeks unspecified "wages due" and damages, as well as shares of Google, profits from the companies "unlawful and/or unfair business practices".More news: Frustrated consumers report credit freeze problems
