SEATTLE (AP) The latest on the Seattle City Council's decision on whether to allow drivers of ride-hailing companies to unionize (all times local):

1:45 p.m.

Seattle could soon become the first city in the nation to let drivers of ride-hailing companies such as Uber and Lyft form a union over pay and working conditions.

The City Council is expected to vote Monday on whether to extend collective bargaining rights for drivers of taxis, for-hire transportation companies and app-based ride-hailing services that are part of the growing on-demand economy.

Supporters say many drivers are immigrants who depend on full-time work, but some make less than minimum wage and lack basic worker rights.

San Francisco-based Uber and others say federal labor law prevents cities from regulating collective bargaining for independent contractors. They say the ordinance would violate federal antitrust laws by allowing independent transportation providers to conspire to artificially drive up transportation costs.
