WASHINGTON— Uber Technologies Inc., Lyft Inc. and other companies that use independent contractors as drivers are launching a campaign to head off Democratic efforts to classify their workers as employees, which would allow them to form unions.
The companies, which also include DoorDash Inc., Grubhub Inc. and several others, plan to run TV and internet ads in the Washington area featuring workers who say they prefer the flexibility of the independent-contractor model over that of a company employee.
