What is the pension position? If he has a very attractive defined benefit pension scheme, then it would be a factor towards staying.
No job is reliable anymore and if your husband can get around €90k net, then it's hard to beat this offer. If the company's financial position is precarious, then getting out now sounds good.
It might be his dream job, but, at worst, he will get a few years at home with the kids. Not too bad either.
If the company recovers after a few years, he may well get his job back.
