Severance agreement arrived, need a second opinion - 12 months and counting

I was offered 16 weeks of severance after 16 years as a store manager, and I have a few days to sign. This is my first time dealing with any of this. I do not want to leave money on the table.

Thanks for writing this out. I went through something close to it 12 months ago, and it settled down once I kept a simple log of every call and form.
