Plant closing and notice period questions (update)

I received a formal notice about a mass layoff at my workplace. I do not know if I should start looking now or wait for severance news. Should I stay for the bonus?

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

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.
