Plant closing and notice period questions - 7 months and counting

Our team was told about a closure date that is 17 weeks away. I do not usually post, so bear with me. Some colleagues are already leaving. Should I stay for the bonus?

Keep everything in writing and save the confirmation numbers. It saved me later.

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
