Verizon Communications Inc said on Monday it will add 1,400 new jobs and provide 10.5 percent in pay raises under terms of a new four-year tentative deal with unions representing about 40,000 workers.

The telecommunications company and the Communications Workers of America had reached a tentative deal on May 27. Details were disclosed on Monday.

The CWA said Verizon agreed to provide a 10.9 percent raise over four years. The reason for the difference in the pay raises was not immediately known.

Workers including network technicians and customer service representatives in the company's Fios Internet, telephone and television services went on strike on April 13 after talks hit an impasse.

Verizon will add 1,300 new call center jobs on the East Coast, and 100 new network technician jobs, Verizon spokesman Richard Young said.

Employees will receive a wage increase of 10.5 percent over the term of the contract that would expire on Aug. 3, 2019, with the first one coming after the contract is ratified by union members, Verizon said in a statement.

The deal provides signing bonuses in the Mid-Atlantic and in the Northeast regions as well as profit-sharing and pension increases, the CWA said.

Proposed company cuts in accident and disability benefits were withdrawn, but both parties have agreed to changes to active and retiree healthcare, the CWA said.

Striking workers will be back on the job on Wednesday. The work stoppage at Verizon stretched across several U.S. East Coast states, including New York and Massachusetts.

Verizon has shifted its focus in recent years to mobile video and advertising, while scaling back its Fios TV and Internet service.

Workers have been without a contract since their agreement expired last August and without healthcare coverage since May 1.

The strike, one of the largest in recent years in the United States, had drawn the support of Democratic U.S. Presidential candidates Bernie Sanders and Hillary Clinton.
