Should I negotiate my severance? - 12 weeks in

I was offered 4 weeks of severance after 4 years as an electrician's helper, and I have a few days to sign. I do not usually post, so bear with me. I do not want to leave money on the table. Should I see a lawyer?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

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