For two weeks pay, I would not agree to anything. For two years pay, I would consider it.
I had no idea that professionals were given such ridiculous offers and expected to sign off on them. At my last job, I was guaranteed 1 year of severance in the event of losing my job. Fortunately, it never happened. At my current job I will get a relatively modest 24 weeks severance if I lose my job. If it ever comes to that, I plan on doing what some of my former co-workers did. Refuse to sign the "release of all claims" unless they give you a year severance and history has shown they'll give it to me.
