Greyhound Lines Inc. and the Amalgamated Transit Union (ATU) National Local 1700 have extended their collective bargaining agreement through Feb. 14. The contract was set to expire Jan. 31, however, the two sides have yet to find common ground on a couple of sticking points, including the company’s plan to create bus routes staffed by Spanish-speaking drivers. “We will continue negotiations to address all of the issues that are important to our employees,” said Steve Gorman, Greyhound’s president and CEO. “In the meantime, our business will operate as normal without interruption.”
