That sucks Z.
Part of the reason why I got out of the private sector so many years ago. Nearly 24 ago to be exact.
I saw 1st hand corporations all across the country letting senior employees go, most often with very little, if any, severance package. Just so disrespectful.
A person dedicates so much of their life to their employer, then w/o any notice..... BAM. Gone. Bye. Don't let the door hit you in the @$$ on the way out. Or even worse, they have you escorted off the property.
Makes me so mad. I've seen it more often than I ever care to acknowledge.
Good luck moving forward.
