As you're being laid off from Fiserv, be certain to double-check and read all of the paperwork thoroughly! They will try to screw you over on your way out, especially by forcing you to shift to arbitration-only and to promise not to sue them for any reason.
Especially read and refuse that stupid non-disparagement agreement that they're eager to force you to sign on your way out. It may cost you some extra cash to refuse to sign it, but your integrity and sanity will thank you.
