National Grid and the unions representing the utility’s workers have reached a tentative labor agreement that averts a possible strike.
The deal was reached Saturday just hours before the prior contract expired.
The president of the Brotherhood of Utility Workers Council says the deal ensures that the utility will maintain current staffing levels, and more than 1,200 workers in Massachusetts and Rhode Island represented in negotiations will get a 2.5 percent raise each year of the four-year deal.
The proposal will be presented for ratification to union members May 20.
A spokeswoman for National Grid tells The Boston Globe the utility is “happy” an agreement has been reached.
National Grid has about 3.3 million electricity customers and 3.5 million natural gas customers in Massachusetts, Rhode Island and New York.
