Three female lawyers who worked at Morrison & Foerster are joining an ongoing lawsuit accusing the firm of gender discrimination, with claims the firm routinely holds back mothers and pregnant women and gives them less pay and promotion opportunities than their male peers.

The three new plaintiffs—proceeding anonymously as Jane Doe 4, Jane Doe 5 and Jane Doe 6 in an amended complaint filed Jan. 25 by lawyers at Sanford Heisler Sharp—join three others who previously sued the firm in a proposed $100 million class action filed in April 2018.
