(TL;DR The main question is stated succinctly at the end)
I'm resigning from a position soon and will be asked to sign some paperwork before going;
I'm generally leaving on good terms.
I've seen some exit paperwork at other companies that involves a separation agreement asking you to agree to certain things, like not saying anything negative about your experience at the company, not disclosing anything about what you've worked on, releasing the company from any potential future legal claims, etc;
At a previous job, they'd waived the repayment of a relocation fee that I would have otherwise owed, in exchange for signing such paperwork (For example they had experienced issues with people leaving negative reviews on sites like Glassdoor, and included a clause in the agreement saying that you agreed not to do so); I know that there's a certain value to it on their end as it resolves potential liabilities and protects their reputation, etc
At the company I'm leaving right now, I don't have anything hanging over my head that they might waive in exchange for me to sign a separation agreement, and I'm wondering.... If I'm not gaining anything for my part in signing.... is there any incentive for me to actually sign?
Would it be super innapropriate for me to ask for some sort of (modest) payment (similar to a severance) as consideration for signing a separation agreement, even though I'm quitting?
Of course I don't want to seem like some kind of jerk when things are otherwise ending on a pleasant note, it's just a question that's been bugging my curiousity
