@OP. I know this cat and mouse game that Ford is playing with us can be devastating for mental health. You'll find other companies out there playing the same game (usually large enterprises). Even medium sized companies will use a bad job market to keep the salaries low.
As an employee, there is not much you can do to change how companies treat their workforce. However, you can change yourself to adapt to this "new" playfield. As others below said, you have to keep your skills current. Stop working for free (no more unpaid OT), and use that time to improve yourself.
Always live below your means. Build a big rainy fund, at least 10-12 months of expenses, and keep it accessible. With the current rates, you can do a ladder CD strategy, which allows to get some extra money on interest.
If you don't have a rainy fund now, start saving while you search for another job. The search for the new job should supersede anything else, but your 40 hours at Ford. The Ford company is too unstable now to allow for anything else.
Personally, I am staying a little bit longer at Ford, due to personal reasons, but I am working on my skills. I don't have any long term plan on staying in this sinking boat. I'll try to ride out the recession, or whatever economical storm is coming soon, here at FMC before I move out.
