Tom Geidt


Tom Geidt brings many years of employment and traditional labor experience to GBG, dividing his time between advice and litigation.  He began his career prosecuting unfair labor practice cases at the National Labor Relations Board for seven years.  Since then he has assisted employers, first in a boutique employment firm, Schachter Kristoff, and then in a large international firm, Paul Hastings, before co-founding GBG (then known as Grube Brown & Geidt) with Jeff Grube and Lisa Brown.

Tom assists employers in all aspects of labor and employment litigation and counseling, with a primary focus on wage and hour law, including the defense of wage and hour class actions.  He enjoys helping employers solve complex, cutting-edge wage and hour problems.  He has provided advice to several hundred employers across the U.S. on a wide variety of issues.

Tom also has successfully defended employers in over 70 wage and hour class actions and PAGA representative actions, first-chaired multiple jury trials, argued before the federal and California appellate courts, and authored briefs to the U.S. and California Supreme Courts.  He regularly handles arbitrations and administrative proceedings before the Department of Labor, Division of Labor Standards Enforcement, NLRB, EEOC, and other administrative agencies at the federal, state and local level.

Bank of America, N.A., 50 Cal.4th 1389 (2010): heavily involved in California Supreme Court case establishing, among other things, that plaintiffs in wage and hour suits may not seek “waiting time penalties” under California’s Unfair Competition Law and thus cannot apply a four-year statute of limitations
