Pros

*Better management than in some previous years. *Great and highly competent HR Generalist although she works between 2 plants. *Good maintenance support and troubleshooting from forklift mechanic. *Very supportive foremen in many areas, the younger ones are very engaged.

Cons

*If corporate had decided to keep this plant open, the full potential of this location could be realized and fleshed out. It may have been too little too late, anyway. I can see why they didn't since it has suffered under deferred maintenance and abuse by previous corporate policies and managers. *Retirement no longer offered. *Occasional coworker who is a walking legally defined hostile work environment among the work staff. *The current live-to-work schedule is deadly. It doesn't matter now that the Portland plant is closed but this would be liability where used in other locations. *Some managers have been split between 2 plants, what I call trying to squeeze juice out of raisins.
