Boeing (NYSE: BA) and the Society of Professional Engineering Employees in Aerospace (SPEEA) reached a tentative agreement on a new six-year contract extension, following several weeks of discussions, the company said. Under the tentative agreement, Boeing would continue to provide SPEEA-represented employees with above-market compensation for their skills. SPEEA health care contributions have not changed since 2008, while health care costs for other Boeing employees and employees across all industries have increased. Under the tentative agreement, employees would see modest increases in cost sharing for participation in the company´s market-leading health care plans in addition to having continued access to a zero contribution health care plan. The tentative agreement includes access to Boeing´s Preferred Partnership health plan in Puget Sound, which provides additional savings to employees.
