Severance offer, what should I ask for? after 3 years as a home health aide

My manager said the package is final, but the letter gives me time to review. I do not want to leave money on the table. What did you ask for?

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

Ask for the offer in writing and do not sign on the spot. A day or two to think is normal.
