Up to half of Chicago's 12,000 cab drivers plan to strike between 6 a.m. and 11 a.m. Monday morning to protest the city's failure to green light a fare increase. The United Taxi Drivers Community Council is upset that new city regulations make it costlier to lease a cab, but the city has not let them pass along some of the costs to passengers.

Any kind of taxi driver strike is a struggle to organize. The Tribune reports that the drivers are independent contractors, and are not part of a single union.
