About 39,000 Verizon landline and cable workers on the East Coast are expected to walk off the job after they say there has been little progress in negotiations since their contract expired nearly eight months ago. The workers, members of two unions - the Communications Workers of America and the International Brotherhood of Electrical Workers - represent installers, customer service employees, repairmen and other service workers in Connecticut, Delaware, New York, New Jersey, Massachusetts, Pennsylvania, Rhode Island, Maryland, Virginia and Washington, D.C., for Verizon's wireline business, which provides fixed-line phone services and FiOS Internet service.
