I was made redundant into early retirement at 53. I did look for work, but back in the mid 1990s women in their 50s were virtually unemployable, at least at professional level, so I did voluntary work and did return to work for 6 months as maternity cover for my manager, but went returned to volunteering when she returned to work.
I would have liked to stay at work. I emjoyed my work and felt I could still make progress. But my employer had a very generous redundancy scheme, especially for over 50s and I had to balance an immediate pension, a big lump sum and other bells and whistles against risking staying on and finding that as soon as the redundancy scheme ended I could still find myself out on my ear, no lump sum beyond my statutory entitlement - a few weeks - and no pension until 60.
So I went. Sometimes it is wise to know the difference between what you want and what is in your best interests.
