But there's also flipside to Kalanick's argument. By not paying for employees' health insurance, Uber saves tons of money, just as it also cuts costs by putting the costs of car ownership onto its drivers.

The suits argue that Uber improperly classifies its drivers at independent contractors, when they should be counted as full employees entitled to employer-provided benefits, including health insurance.
