Layoff notice, what does the 60 days mean? - what worked for you?

My employer announced that the site will close and gave us written notice. I am in Portland, in case local advice matters. I do not know if I should start looking now or wait for severance news. 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.
