Oracle systematically underpaid thousands of women, lawsuit says

Class action alleges female workers were paid average of $13,000 less per year than men doing similar jobs

Thousands of women were systematically underpaid at Oracle, one of Silicon Valley's largest corporations, according to a new motion in a class-action complaint that details claims of pervasive wage discrimination.

A motion filed in California on Friday said attorneys seek to represent more than 4,200 women and alleged that female employees were paid on average $13,000 less per year than men doing similar work. An analysis of payroll data found disparities with an "extraordinarily high degree of statistical significance", the complaint said. Women made 3.8% less in base salaries on average than men in the same job categories, 13.2% less in bonuses, and 33.1% less in stock value, it alleges.
