For those that are affected, look at your unvested HSA (or whatever it is called). That account is held in escrow until you are laid off. It is extremely rare for anyone that is let go to have a vested balance. Mine was about $29k when laid off. My severance was under that amount. So, when I got laid off, they pay my severance, and MAKE money of the unvested HSA account.
If you don't believe me, go look at your balance. I will bet almost all being laid off have a higher unvested balance than the cost of letting you go. This single handedly proves you are nothing more than an expense to them.
