when you are fired, you are free to disparage your former employer. she was not free to do that because she signed away that right, and you can only sign away something in exchange for something, which she obviously took.

when you don't mention or acknowledge this aspect, you are not making a convincing argument. perhaps they gave her a very attractive severance package, and you don't know that they didn't, so how can you draw a conclusion?

life threatening health problems is not a free pass to "i get whatever i want", not for me, not for you, and not for her, although we know that in the world of Karens it is an entitlement.
