For investors this is a positive development for two reasons. First, it sets the tone for Boeing's pension plans, as union workers under the new contract gave up their pension-style retirement plan for a 401(k)-style contribution plan. That will help bring down Boeing's long-term pension costs which have dragged down earnings. Second, it will also secure Everett's workforce, which is experienced with 777X production, rather than selecting another location where budget overruns and production delays would be more likely.
