NEW YORK (AP) — General Electric Corp. said Monday that it agreed on tentative labor deals with two of its biggest unions after a month of talks.

The conglomerate's agreements with IUE-CWA and the United Electrical, Radio and Machine Workers of America are subject to review by union negotiating committees and ratification by union members by June 30.

GE's existing contracts with the unions expire at midnight.

The company said unions affected by the tentative agreements represent about 15,200 GE workers in the U.S. The IUE/CWA represents approximately 7,900 GE workers, while the UE represents about 3,100 employees. Contracts negotiated with additional unions at the local level represent more than 4,000 unionized workers.

The new four-year agreements provide better wages, pension and job and income security, the company said.

IUE-CWA local union leaders will meet Wednesday to review the tentative deal and decide whether to submit it for a ratification vote. The UE conference board will meet Tuesday to review the contract and will make a recommendation on Thursday. If recommended for approval by union leaders, the ratification votes will be conducted by June 30.

The deal with the IUE/CWA covers GE locations including Louisville, Ky. (GE Appliances); Lynn, Mass. (GE Aviation); and Schenectady, N.Y. (GE Energy). The UE deal includes GE employees in Erie, Pa. (GE Transportation) and Fort Edward, N.Y. (GE Energy).
