Plant closing and notice period questions after 5 years as a graphic designer

My employer announced that the site will close and gave us written notice. I do not know if I should start looking now or wait for severance news. Should I stay for the bonus?

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

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