Have you considered working for a charity as a volunteer? The range of opportunities goes way beyond standing behind the counter in a charity shop, enjoyable but not everyone's cup of tea. In my area the range of voluntary jobs ranges from helping look after the donkeys in a donkey sanctuary,to caring for redundant churches to running helplines - and that is only ones I know of. My county council has a voluntary work opportunities page on its website and some areas have Volunteer Centres.
If you enjoyed your work and have skills that could be useful in the voluntary sector look for a suitable opportunity. Some years ago I was made redundant into early retiremment, after a year trying to find work I took my skills to the voluntary sector and quickly found a suitable opportunity.
