A Supreme Court judge in Brooklyn has fined the Transport Workers Union (TWU) $2.5 million for the illegal strike that crippled the city.

In addition to the fine, the judge indefinitely suspended automatic dues collection for the 33,000 members of TWU Local 100. The union will be allowed to reapply for the collection service after 90 days. The judge earlier this month also ruled that union president Roger Toussaint be jailed for 10 days and fined $1,000 for criminal contempt.

The strike, which stemmed from a contract dispute with the Metropolitan Transportation Authority (MTA), shut down all subway and metro bus lines. In staging the 60-hour walkout during the December holiday shopping season, the union violated the state Taylor Law, which bars public employees from striking.
