Lawyers from four Houston trial firms were on separate sides of a recent trial. But now they are jointly representing a teenage alternate juror who was fired during his jury duty.

The juror, Zachary White, filed a petition Friday in state district court in Houston, alleging that Mercedes-Benz of The Woodlands fired him on Feb. 25 for failing to show up on Mondays and Saturdays for “scheduled shifts outside of the jury duty schedule.” White alleges in the petition, however, that he was “not officially scheduled” for work on those Mondays and Saturdays while he was on the jury.
