Verizon workers in nine states could walk off the job as soon as early Sunday if union negotiators don't reach an agreement over benefits with the wireless carrier.
A contract covering 39,000 Verizon workers represented by two unions expires at the end of Saturday. Last week the Communication Workers of America announced that 86 percent of Verizon workers covered by the contract voted to strike in a recent poll, if a new agreement isn't reached.
The contract covers employees in nine states from Massachusetts to Virginia who work for Verizon's wireline business, which provides fixed-line phone services and FiOS Internet service.
The unions say the telecom giant is demanding that workers sharply increase their health care contributions and make concession on pensions.
