Severance offer, what should I ask for? - what worked for you?

My manager said the package is final, but the letter gives me time to review. It has been weighing on me all week. It includes health coverage for a couple of months. What did you ask for?

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.

I asked for two more weeks and a neutral reference. They agreed to the reference and added a week.
