Seattle sued over city ordinance that allows Uber, Lyft drivers to unionize

US Chamber of Commerce suit is latest in legal battle over whether drivers are independent contractors or employees and what rights they should have

The US Chamber of Commerce sued the city of Seattle on Thursday over an ordinance that allows drivers of ride-hailing apps Uber and Lyft to unionize, saying it violates federal antitrust laws.

Seattle last year became the first US city to pass a law giving drivers for companies such as Uber and Lyft, as well as taxis and for-hire drivers, the right to collectively negotiate on pay and working conditions.
