After initially keeping silent, Jones Day has responded publicly to a $200 million proposed gender bias class action brought by six associates last week, vowing to fight the claims and touting its commitment to women's inclusion and advancement.

In a statement posted on the firm's website, Jones Day said it provided women with flexibility in their path to partnership and highlighted the leadership roles women play in the firm. The majority of its women partners are mothers who took family leave and often worked flexible schedules, the statement said.

"Jones Day is proud of its success in promoting a diverse group of outstanding lawyers," the firm said. "The success of Jones Day's women lawyers has been supported by our inclusive culture that rewards talent, teamwork, integrity and mutual commitment to our clients and the firm."
