Uber drivers set their own hours, file taxes independently, and often own their cars. They don’t get health insurance from Uber and they don’t wear uniforms. And yet, Uber controls much of what they do by setting prices, handling their tips, and micromanaging them through its driver rating system. Are these drivers independent contractors, working for a strict boss? Or are they employees, entitled to benefits and covered expenses?

A law firm has filed a class action lawsuit against Uber in California on behalf of the state’s drivers, alleging that the company had misclassified them as independent contractors. Uber is going to the mat to defend the status quo, arguing that the class is too large, that drivers want to be independent contractors (which isn’t really material to their classification), and even trying to make itself seem more like Wal-Mart.
