Plant closing and notice period questions (St. Louis)

Our team was told about a closure date that is 3 weeks away. I have read a lot of threads here and could not find my exact situation. Some colleagues are already leaving. 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.

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