Normally, independent contractors are not subject to minimum wage requirements, since those laws (such as the Fair Labor Standards Act) apply only to employees. Lots of litigation focuses on whether contractor drivers should, in fact, be classified as employees and therefore subject to minimum wage and overtime rules, but if the drivers are properly classified as independent contractors, minimum wage requirements typically do not apply.
But under a new rule in New York City, ride share drivers are now entitled to a minimum wage in excess of $15 per hour, despite being independent contractors.
