I spoke recently with a current Easyjet f/o who was forced to join as flexi crew.
Money was ok to start with, plenty of hours, But no extras such as pensions, loss of license or sick pay. Now though the number of hours he gets are reducing so therefore does his pay.
He was very worried about the new permanent contracts to be offered as although they would be permanent, the salaries would again be much lower(turbo prop levels). To low to survive on, he said( mortgage, loan etc).
Of course these people would then be used as preference over flexi crews.
He seemed to think that the new contracts would result in a larger exodus than before. All his friends were already looking elsewhere for better contracts (Monarch, Jet2, Middle East).
