Greenberg Traurig said Tuesday that John Scalia, son of late U.S. Supreme Court Justice Antonin Scalia, has rejoined the firm as a shareholder in its Northern Virginia office and as a member of its global labor and employment practice.

Scalia spent 12 years at Greenberg Traurig before leaving to become a shareholder at Littler Mendelson in 2013. Two years later he moved to Pillsbury Winthrop Shaw Pittman, where he was senior counsel. His practice involves representing employers, including in arbitration and mediation proceedings, in federal and state courts, and before federal and state agencies.
