New Yorkers are trudging through their third day without bus or train service, as a transit strike keeps the city in turmoil.

As residents walked, jogged or biked to work this Thursday morning, union leaders and transit officials met for their first talks since the strike began.

That meeting came after three union leaders were threatened with jail for defying a state law against strikes by public workers. The union already is being fined $1 million each day of the walkout.

The strike has shut down New York's huge subway and bus network, crippling normal travel arrangements for millions of people. Business is down sharply at the city's famous shops and department stores, as well as at restaurants, museums and theaters.

The strike also comes during the busy holiday period, costing the local economy hundreds of millions of dollars a day.
