The proper responsibility of a concerned manager in this case is to make sure the person knows you have their back in terms of future references, petty resources (one guy I knew was on the hook for >$300 in reimbursements when laid off, as far as I know he never got them - another guy was forbidden to take his personal mouse/keyboard home with him), and similar things. If a mid-level manager actually cares, and was any good at their job, the best thing they can do is to keep doing it for that person.
