Elon Musk has yet another class action lawsuit to contend with over his handling of mass layoffs at Twitter. The latest comes from two former employees who allege “women were significantly affected more than men” in the November layoffs that cut nearly half its workforce.

According to the lawsuit, a total of 57% of women employees were laid off, compared with just 47 percent of men. It goes on to note that the disparity can’t be explained “based upon a justification that Musk intended to retain more employees in engineering-related roles” because women engineers were also cut at a higher rate than their male counterparts.

It states that “63% of females in engineering-related roles were laid off on November 4, 2022, while 48% of male employees in engineering-related [roles] were laid off.” For non-engineering roles, there was also a “great disparity” between men and women who lost jobs, with 51% of women and 42% of men affected by the cuts.

The lawsuit also cites numerous tweets from Musk that show his “discriminatory animus against women,” and claims that his requirements for employees to work up to 12-hour days as part of an “extremely hardcore” Twitter 2.0 is also has a “a disproportionate impact on women, who are more often caregivers for children and other family members, and thus not able to comply with such demands.”

The lawsuit is at least the fourth class action suit brought against the company following mass layoffs in November. Former employees and contractors are also suing the company over violations of the US Worker Adjustment and Retraining Notification (WARN) Act, which stipulates companies with more than 100 employees must provide at least 60 days notice ahead of mass job cuts. Another former employee has brought a suit against the company, alleging that Musk’s demand forcing all workers back to the office discriminates against people with disabilities.

Elsewhere, Musk is also facing an investigation from San Francisco city officials in the wake of reports that Twitter has set up hotel-like bedrooms inside of its offices for employees.
