Layoff notice, what does the 60 days mean?, accounts payable clerk here

My employer announced that the site will close and gave us written notice. I have read a lot of threads here and could not find my exact situation. I do not know if I should start looking now or wait for severance news. Has anyone been through this?

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

Start your search early. I wish I had begun the day of the notice.
