Miles offtarget, although it's not as good a scheme as most of us would have liked, Seasonal working at bmibaby was a choice between a permanent job or redundancy for those affected by the criteria.
For the benefit of fact, they get 71% of basic salary year round but a variable roster pattern ranging from 100% full time during the summer to 50% in the winter. Note that they also get 71% salary when working the 50% roster in the winter.
The day off bought rate when working 100% rosters is the same as a full timer.
