In December 2005, the TWU Local 100 called a strike in New York City. Negotiations for a new contract with the Metropolitan Transportation Authority (MTA) broke down over retirement, pension, and wage increases. The strike began at 3:00 a.m. EST on December 20. Most New York City Transit Authority and MTA Bus Company personnel observed the strike, effectively halting all service on the subway and buses, except for routes operated from the Spring Creek Depot, where workers represented by ATU Local 1181/1061 had a contract in force after striking against the predecessor operator, Command Bus Company, the previous year. Millions of commuters were affected. The strike officially ended at 2:35 p.m. EST on December 22, 2005. Service was restored overnight, with all transportation systems fully operational by the morning commute of the 23rd.
