A union says nearly 40,000 striking Verizon employees will return to work Wednesday after reaching a tentative contract agreement. It includes 1,300 new call center jobs, nearly 11 percent in raises over four years and the first contract for Verizon wireless store workers. The Communications Workers of America union announced the tentative pact Monday with Verizon Communications Inc. They’d reached an agreement in principle Friday but hadn’t released details or a date for the workers’ return from one of the largest strikes in the United States in recent years. Verizon says a tentative agreement to end one of the largest strikes in the U.S. in recent years is good for both employees and the business. Union members will vote on the deal after returning to work. Landline and cable employees in nine Eastern states and Washington, D.C., struck in mid-April. Other workers stepped in, but there were some holdups.
