Proskauer Rose has been hit with a $10 million gender discrimination suit by its former chief financial officer, Elly Rosenthal, who alleges the firm marginalized her and eventually fired her after she took leave for breast cancer treatment (See Complaint).

In Rosenthal v. Proskauer Rose, 111343-11, filed yesterday in Manhattan Supreme Court, Ms. Rosenthal, 57, accuses the firm, which has more 650 attorneys in 12 offices, of demoting her after her medical leave, denying her pay increases and eventually replacing her with a man who was less qualified, despite her 16 years of excellent performance.
