Apple has spent years “intentionally, knowingly, and deliberately paying women less than men for substantially similar work,” a proposed class action lawsuit filed in California on Thursday alleged.

A victory for women suing could mean that more than 12,000 current and former female employees in California could collectively claw back potentially millions in lost wages from an apparently ever-widening wage gap allegedly perpetuated by Apple policies.

The lawsuit was filed by two employees who have each been with Apple for more than a decade, Justina Jong and Amina Salgado. They claimed that Apple violated California employment laws between 2020 and 2024 by unfairly discriminating against California-based female employees in Apple’s engineering, marketing, and AppleCare divisions and “systematically” paying women “lower compensation than men with similar education and experience.”
