SEATTLE (AP) - The Boeing Co. has presented its first full offer for new three-year contracts to the union representing its engineers and technical workers.

The Society of Professional Engineering Employees in Aerospace calls it incomplete and disappointing.

The summary outlined late Thursday on the Boeing Web site was light on details but Doug Kight, Boeing vice president of human resources, says the company is working toward contract offers that reward those employees "for the amazing work that they do every day."

Boeing says the offer includes unspecified pay raises in each year of the contract "through an annual salary adjustment fund." The offer also includes pension increases for current employees but proposes eliminating the defined benefit pension for new employees.

The union represents about 21,000 workers, mostly in the Seattle area and others in Oregon, Kansas, Utah and California.

Chief SPEEA spokesman Ray Goforth says Boeing "continues to press for removing Utah engineers from the professional contract."

SPEEA's two contracts expire on Dec. 1.

Boeing machinists began returning to work last Sunday after an eight-week strike.
