My wife went through her job being made redundant a few years ago. She didn't have a choice but to leave where she was working for over 20 years.
The money was good but as you'll mostly find with a lump sum of money, it ran out with some house renovations etc.
I remember how upset she was at the time but looking at it now, she agrees it was the best thing to ever happen to her.
Overall, if you take the money, it's a change and they say a change is as good as a holiday!
The only word of caution I have for you is speak to an accountant as I think, although not exactly sure, that there are different tax rules for volutany redundancy v's forced redundancy. I thought forced redundancy was taxed less, but again, not sure and you should really find out as it can make a big difference to the $$$$ that end up in your bank account at the end of the day.
Hope this helps.
