Sounds to me like you would be better off taking the voluntary route.

Redundancy of any kind is rarely fun at the time, but 6 months after mine I wished it had come years before! Now retiring 20 years on and I couldn't possibly have been as well off with my old career - it really was the best thing that ever happened to me, workwise.

The main thing is to not beat yourself up about it, you know your own worth, even if you think they don't.
