The chemistry is already lost between your hubby and the company. Go for next job. 3 Month severance pay is a pretty good deal.
He will feel very unhappy even he can find a way to stay.
A good working horse should be able to find a job very quickly.
I was laid-off 2 years even I had a lot of loves to the company. I really felt upset at that moment. But my new job now gives me much more $$$.
Frankly speaking, this lay-off could be the best thing happening to your hubby and your family.
Be adventurous.
