Some work is rumoured to be being offered to some of the cadets over the winter but I have not yet met anyone who has been formally offered that deal.
As far as I understand, that's definitely happening. I know people who have been offered a certain number of days per month flying for easyJet over the winter on this basis. These will be on CTC FlexiCrew terms (i.e. not a new intake of fresh cadets on the 6-month probation £1k/month contract.).
