Layoff notice, what does the 60 days mean? (Chicago)

I received a formal notice about a mass layoff at my workplace. I worked as a home health aide before 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 settled down 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.
