This site seems like just griping, but I just got the boot after 20+ years, so I've seen the severance package for US (I am going to retire, so not so bad for me). Although access to Citrix networks is cut off on Nov 15, the "Final Date of Employment" is December 1, so we get an extra 2 weeks pay in addition to severance package which, at least in US, is X weeks for pay level + 2 weeks per year up to 15 years. After 15 years, no bump in package or in PTO days.
Also, by setting the Final Date of Employment to December 1 instead of Nov 30, we get the whole month of December normal benefits.
At least some of us with RSUs that vest in the next 12 months will get those too, although the generic package info does not say that.
I chose to stay through thick and thin and enjoyed working with a lot of great people.
