Wm. Robert Gignilliat, IV, is an Associate in the Greenville, South Carolina, office of Jackson Lewis P.C. His practice covers a broad range of employment law matters, including litigation and preventive advice and counsel.

Wage-and-hour litigation is a major component of Mr. Gignilliat’s practice. He has defended numerous class and collective actions alleging violations of the Fair Labor Standards Act, state statutes on overtime and wage payment, and common law principles on wages.  In defending these cases, he has experience with pleadings, discovery, timekeeping and payroll data analysis, drafting and arguing dispositive motions, fighting class certification, trial preparation, mediation, and strategic considerations. In April 2016, he took part in an intensive, three-day training program on the defense of class and collective actions with a focus on wage-and-hour litigation. 

In addition, Mr. Gignilliat has substantial experience defending employers and insurers in single-plaintiff cases involving discrimination, harassment, retaliation, employment contracts, non-competes, wrongful termination in violation of public policy, and denial of disability benefits under ERISA.

Mr. Gignilliat also regularly advises employers regarding employee discipline, ADA and FMLA leave, wage-and-hour issues, employment contracts, and other preventive measures to avoid litigation. 

While attending law school, Mr. Gignilliat was a member of the Georgia Law Review. After law school, he clerked for two years for the Honorable J. Randal Hall in the U.S. District Court for the Southern District of Georgia. He then clerked for the Honorable G. Ross Anderson, Jr., in the U.S. District Court for the District of South Carolina.
