For severance they do a calculation based on max of 1 week per year of service or a minimum based on your pay position grade. If you were on Unlimited R&R or considered position grade 11, the minimum is 10 weeks.
You also get 45 days of outplacement service. 2 week pay in lieu of notice. Subsidized cobra at existing rate for 6 months.
Bumping this from the "Severance Question" thread as it is relevant info that should stay on top. Original is at @2ojj+1j8uSviE.
