Amy Miller, a former partner at Levi & Korsinsky in New York, sued the plaintiffs securities law firm for discrimination Tuesday, alleging she was underpaid, and ultimately fired, because of the name partners’ flawed and antiquated beliefs about working mothers.

Miller, who is now of counsel at Cohen Milstein Sellers & Toll, said Eduard Korsinsky promoted her to partner at the end of 2017 but never followed up on his promise to give her a raise, nor did he ever give her the “commissions” that certain male partners at the firm receive for winning big cases. Her bonuses were on par or lower than what a male associate received, she claimed in a lawsuit in Manhattan federal court.
