Boeing machinists vote Sunday on contract offer. A strike may affect defense projects and put St. Louis in the spotlight on labor disputes.

Boeing retracts its proposal to alter machinist work schedules in its new contract offer, which will be voted on by union members this Sunday morning.

Boeing made a new offer Thursday to the local machinists union, with a strike just days away. There’s no change to the 20% pay increase over the four-year contract, but this new offer does remove a controversial work schedule change and adds a 50-cent per hour pay increase to those at the top of the scale with good attendance.
