Oracle has been sued (PDF) for gender discrimination by three female former engineers who allege they were paid less than men in similar roles.

The proposed class-action case was first reported on Friday by The Information, which said it was filed in August. Records from San Mateo County Superior Court, where the case was filed, indicate that it was actually first filed in June and then amended on August 28 to add a third plaintiff.

The lawsuit was filed by the same law firm, Altshuler Berzon, that sued Google last month on similar grounds, with three female ex-Googlers as named plaintiffs. Like the Google case, the Oracle lawsuit mirrors accusations first made by the government. In January, during the final days of the Obama Administration, the US Department of Labor brought a case against Oracle , saying that the company pays women "less than comparable males in comparable roles." The government case also alleges racial discrimination.

Oracle called the government's January lawsuit "politically motivated, based on false allegations, and wholly without merit." The company declined to comment on the proposed class-action lawsuit reported Friday.

The lawsuit names three female engineers and says they were all paid less than men for "substantially equal or similar work."

Rong Jewett worked as an application engineer at Oracle from April 2012 until July 2016. Sophy Wang also worked in application engineering, beginning her stint at Oracle in October 2008 and leaving around March 2017. Xian Murray, the third plaintiff, worked at the company from March 2011 until October 2016. All three worked in the company's Redwood Shores, California headquarters.

Like the lawsuit against Google, the Jewett v. Oracle complaint alleges violations of the California Equal Pay Act and other sections of the state labor code.

Because Oracle is required to maintain records of wage rates and job classifications for all California employees, the company "knew or should have known" that it paid female employees less than their male counterparts, the complaint states.

On Thursday, Oracle's board recommended that shareholders vote against a proposal that the company produce a report on the gender pay gap. The proposal, which was disclosed in an SEC filing and reported by USA Today, notes that other tech companies, including Google, Microsoft, and eBay, have done gender pay assessments and published the results.
