Layoff notice, what does the 60 days mean? - 3 months and counting

Our team was told about a closure date that is 5 weeks away. I have read a lot of threads here and could not find my exact situation. They offered a retention bonus for people who stay. Should I stay for the bonus?

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