This may seem a bit naïve, but I would like to think for an airline with the scale of Easyjet it would not be beyond the wit of man to device rosters that both maximised working hours and let people rest.
Is the problem a lack of will on the part of management or the nature of the beast?
What would a 'decent' EASA compliant roster look like, and is it deliverable given the economics of the low cost model?
