PHILADELPHIA (WPVI) -- The union representing more than 5,000 SEPTA workers who operate buses, trolleys and subways in Philadelphia said Friday that a strike is imminent.

Members of Transport Workers Union Local 234 , which is SEPTA's largest workers union, have been working without a contract since Nov. 7.

Negotiations with the transit agency began in October.

"I can tell you now that my patience has run out. I'm tired of talking and we're about to start walking," said Will Vera, president of TWU Local 234, during a news conference on Friday afternoon.

Union leaders say they are seeking modest raises, pension increases, changes to working conditions and health care improvements.

"A strike is imminent," said John Samuelson, international president of the Transport Workers Union.
