NOTTINGHAM, MD— General Motors and union leaders reached a tentative agreement on a new labor contract on Wednesday that could end the United Auto Workers’ month-long strike, CNBC reports.

The work stoppage has been the UAW’s longest strike against GM since 1970.

Details of the agreement weren’t immediately made available, and the deal is expected to take about two weeks to finalize.

The new deal still needs to be approved by local union leaders and General Motors’ 48,000 UAW members, who have been on strike since the middle of September.

“The number one priority of the national negotiation team has been to secure a strong and fair contract that our members deserve,” UAW Vice President Terry Dittes, director of the UAW GM department, said in a statement.

The UAW’s national negotiating team is recommending that union members accept the deal.

County Executive Johnny Olszewski met with striking workers in White Marsh last month.
