Updated 6:10 p.m: John Stout, director of communications of Lockheed Martin issued the following statement about the strikes: “We believe our offer included terms that constituted a fair and equitable contract for the IAM members, including wage increases of 3 percent annually in each of the three years, a $3,000 signing bonus, an annual cost of living supplement of $800, increased retirement income for current employees, and various other improvements. We’re disappointed that the IAM members rejected the company’s last, best and final offer and voted to strike. Our operations will remain open and we will implement our contingency plan while focusing on meeting our commitments to our customers.”

Updated 4:30 p.m: The strike goes into effect at 12:01 a.m. on Monday. Picketing will begin at that time. 2,653 members voted to go on strike compared to 181 who voted against it. Members told CBS11 the major reasons behind the company-union tension are  fewer and more expensive healthcare options for workers and an effort to do away with pensions for new employees.
