Chicago cab drivers say they'll strike for 24 hours starting Sunday because of concern over fares.
Many protested outside of Chicago's City Hall on Tuesday.
They are asking for a 16% fare increase citing difficult economic conditions. Earlier this month, a fuel surcharge was eliminated after the price of gas fell.
A spokesman for United Taxidrivers Community Council says they've told city officials that the fuel surcharge is not the issue.
He says drivers need a more reliable means of income and the 16% increase is for increased cost of living.
The drivers say a strike could paralyze the city.
