Management at the Pilgrim nuclear plant in Plymouth and unionized workers have reached a tentative contract agreement.
The Utility Workers Union of America Local 369 announced the agreement early Tuesday morning. Union membership is schedule to vote on the proposal Wednesday.
Union president Dan Hurley said in a statement that the contract ‘‘has important protections’’ for the workers.
Entergy executive Robert Smith called the four-year labor contract ‘‘fair and equitable.’’
No details were released.
Contract negotiations had stalled over health care costs and working conditions.
The dispute became contentious with plant owner Entergy Corp. locking out union workers and the union filing labor complaints with the National Labor Relations Board.
In response to the agreement, the union said a rally outside the Statehouse planned for Tuesday had been cancelled.
