NEW YORK (AP) -- A strike by thousands of workers in Verizon's wireline division could potentially affect landline operations as well as installation of services like FiOS, its fiber-optic television and Internet lines.
Verizon says it has taken steps to avoid lessen the effects such as training managers and retirees.
The dispute does not affect the company's wireless division.
The contract for the 45,000 employees from Massachusetts to Washington, D.C., expired at midnight Saturday with the company and the workers unable to come to terms on issues including health care costs and pensions.
Verizon is asking for changes in the contract because it says its wireline business has been in decline for more than a decade as more people switch to using cellphones exclusively.
The union says the company wants worker concessions at a time when it's making billions in profits and top executives are making millions in salary.
