David Lavitman, a Milton driver who signed up for Uber, has sued the car service, claiming its illegally keeping half drivers' tips.
Lavitman filed his suit in state court in December, but Uber had it moved to federal court this month.
Lavitman alleges the company collected a 20% gratuity fee on all rides, but only gave half that to drivers.
Uber tells the Boston Business Journal [2] drivers keep all the gratuities, but that it does take a percentage of the meter fee plus $1 per trip.
