The second-largest union at Boeing has filed a unfair labor complaint against the company. Filed by the Society of Professional Engineering Employees in Aerospace last Monday, the complaint accuses the company of violating a settlement related to its employee incentive plan. The union believes the plan is a anti-union program as the company has in the past said it is limited to non-union employees. The complaint filed with the National Labor Relations Board asks the company to refrain from applying the incentive program only to non-union employees.
