Over 3,200 Boeing union workers in St. Louis voted to strike after rejecting a proposed contract that included a 20% wage increase over four years. The union cited the contract as failing to meet worker priorities. A 'cooling off' period delays the strike until August 4th. Boeing, who called the offer their richest ever, is preparing for the strike. The rejection comes as Boeing prepares to announce second-quarter earnings, following a strong increase in aircraft deliveries.
