Should I negotiate my severance? - 11 months and counting

I was offered 14 weeks of severance after 14 years as an event coordinator, and I have a few days to sign. Thank you in advance. I do not want to leave money on the table. Should I see a lawyer?

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

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