Engineer,
I've been in that situation, so I totally know what it feels like to see a plant shutdown. I worked as a process engineer for "thin film" manufacturing facility that was formerly owned by Du Pont. The workers there had over 30 years experience, and new management came in and laid off half the workforce in a day. Eventually the plant was shutdown, re-opened, shutdown.....sold off......etc
Its hard seeing very experienced people be let go based on the headcount numbers. To make matters worse, this plant was the largest employer in the area, and really decimated the economy there.
Anyways, Good luck on the job search. If you are really up for it, you may want to go back and get your PE certification and work in design.
