BOSTON (AP) – Members of the union representing more than 1,900 striking NStar workers overwhelmingly approved a new contract Tuesday night, the union’s president said.

Gary Sullivan, president of Utility Workers Union of America Local 369, said the vote was 87 percent in favor of the new deal.

The union had been on strike for two-weeks against the electricity and gas utility.

Of 1,466 total votes cast on the contract, 1,277 were in favor and 189 against, he said.

Union leaders had recommended approval of the four-year deal reached over the weekend, after a mediator called the sides back to the bargaining table for the second time since the strike began on May 16.

The agreement would give NStar greater flexibility to schedule crews to repair overhead lines during the late afternoon and in the evening, rather than paying day shift workers overtime to handle that work.

The union won a pledge to hire more workers for dedicated maintenance crews, and the company dropped some proposed pension and benefit cuts.
