Boeing union workers who assemble fighter jets strike in two states following rejection of contract offering 20% general wage increase and $5,000 bonus.

Saying “enough is enough," thousands of workers at three Boeing manufacturing plants went on strike overnight.

More than 3,200 union members who assemble Boeing's fighter jets in the St. Louis area and Illinois went on strike on Monday after rejecting a second contract offer the previous day. Boeing Defense said it was ready for the work stoppage and it will implement a contingency plan that uses non-labor workers.
