Six political leaders have urged machinists in the Puget Sound to accept a proposed contract from Boeing that moves them away from a fixed-payment pension plan—even though the officials have the same type of retirement package.

On Monday, government and other officials gathered in Everett, Wash., to talk about the importance of machinists accepting a new contract this week. Six called on union members to accept the deal, including one who is already drawing pension payments and five others who are expected to do so upon retirement.
