The Transport Workers Union Local 100 walked off their jobs, shutting down transit systems over a contract dispute. The city implemented mandatory carpool requirements, where cars entering the central business district were required to carry three or more passengers and the strike birthed the popular "dollar vans", independent operations that charge a small fee for rides and service areas outside the reach of the transit system. Other commuters walked, biked, or roller-bladed across the city. The union would eventually receive a smaller pay increase and a cost of living adjustment, and the MTA then raised fares 20% to make up the difference.
