In Sweden this kind of work is called 'practice' work and it's expected of benefit receivers to step up to the plate. They are not paid a wage, however they see getting benefits as payment. It's more or less reserved for those who have been on benefits for years, but it can be requested.
I'm back on benefits again after finishing my summer job, and I'd be throwing myself at fruit picking jobs if there were any round here. We have a lot of fruit farms, but just like the 'pick your own' in the UK most fruit farms here sell direct from the bush/tree or mechanically harvest and are typically a small section of a much larger grain farm.
Interestingly, however, a plot of land right beside my apartment is being dug up by the council. They will plant a lot of fruit trees and bushes purposely for keeping everybody in free fruit all year round. Fruit is also given out at workplaces for free. (Sweden)
