Should I negotiate my severance? after 18 years as a production planner

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?

Thanks for writing this out. I went through something close to it 4 months ago, and it got easier once I kept a simple log of every call and form.

Read the release carefully. Mine included things I did not expect, like a non-compete.
