Boeing St. Louis machinists, represented by the International Association of Machinists and Aerospace Workers (IAM), rejected a new contract offer from Boeing Defense. The offer included a 20% wage increase over four years but was deemed insufficient by union members. The current contract expires at 11:59 p.m. Sunday unless a new agreement is reached. Union members cited the proposal's failure to address their priorities and ensure a secure future.
