The point that tends not to be stressed enough is that decent T&Cs for pilots (particularly debt-ridden flexi-FOs) is a matter of safety. Consider, if you will, the plight of the Parc guys who were threatened with the sack unless they accepted a financially-crippling 2-year Berlin contract. Some of the guys going are now not expecting to be able to meet even just their loan-repayments for the month - never mind earning enough to cover food/rent in Berlin. Already a few of them are organising second jobs in bars/restaurants.
Consider what WILL be happening in SXF in just a few weeks - FOs will be doing their 5am - 1pm early, heading home and changing into his/her bar uniform and working the evening shift until midnight or later. Home to bed for a couple of hours sleep and back down to the eJ crew room for 5am the following morning. Repeat.
Its a horrible thought but it seems the surest way to kill the flexi epidemic will be a hole in the ground.
