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

My employer announced that the site will close and gave us written notice. This is my first time dealing with any of this. They offered a retention bonus for people who stay. What did the workforce office offer?

I stayed for the retention bonus and looked for work on the side. It cushioned the gap.

The workforce board ran a rapid-response session for us with résumé help and information on benefits. Ask if yours will.
