Should I negotiate my severance? (Tampa)

My manager said the package is final, but the letter gives me time to review. I worked as an office manager before this. There is a non-disparagement clause. What did you ask for?

Thanks for writing this out. I went through something close to it 10 months ago, and it got easier 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.
