Anyone who thinks that terms and conditions are going to improve down the road are extremely niave.
Even in the good times that have passed people are willing to pay for overpriced courses (Easyjet / BA / Virgin) be employed by agencies on low pay zero hour contract to get their hands on a shiny jet (Norwegian / Ryanair).
The airlines see this and they are going to abuse it in the future because there is a never ending line of mugs willing to set the bar even lower just so they can get their hands on a shiny jet.
