Severance offer, what should I ask for? after 3 years as a project coordinator

I was offered 3 weeks of severance after 3 years as a project coordinator, and I have a few days to sign. There is a non-disparagement clause. Should I see a lawyer?

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

An hour with an employment lawyer cost me a small fee and made me feel much safer about signing.
