Plant closing and notice period questions - any advice?

I received a formal notice about a mass layoff at my workplace. This is my first time dealing with any of this. They offered a retention bonus for people who stay. Has anyone been through this?

Thanks for writing this out. I went through something close to it 7 months ago, and it got easier once I kept a simple log of every call and form.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
