Must be your first time getting fired ;-)
IANAL but...
1. The vacation time is yours - don't let them bluff you.
2. you'll probably have to sign to get the severance
3. don't sign until you get a lawyer to look it over.
Goood advice in this post. I would add start working very hard in finding new employment. ASAP The more resumes you get out there the better. Hunt hard and give yourself options. Good Luck
I have a disability and I have never, ever slacked off from work a day in my life.
I'm frustrated and angry and embarrassed as hell.
