A former Jones Day associate who is now an in-house attorney for Facebook has joined a gender bias lawsuit against Jones Day, making her the third named plaintiff in the case.

The lawyer, Jessica Jardine Wilkes, was an associate at Jones Day from October 2014 to September 2016, and is now product counsel at Facebook in Menlo Park, California, according to her LinkedIn profile and state bar records.

Employment class action firm Sanford Heisler Sharp brought the case against Jones Day in April on behalf of former associates Nilab Rahyar Tolton and Andrea Mazingo, as well as four anonymous women. Lawyers at Sanford Heisler and Jones Day argued in Washington, D.C., federal district court last month over whether the unidentified women should be able to keep their anonymity in advance of any trial.
