I never actually worked for Cabair but I do have a mate who recently jacked in the KLM uk deal with them after instructing with them for nearly two years.
He has done his own IR and now has a job with another airline. During his time at Cabair he suffered two paycuts a reduced working week to get round employment rules and minimum wage obligations and very poor morale. I visited him when I was in London doing my MCC and he and his flat mate were facing warrant sales for non paymeny of council tax and their phone had been cut off!
Instructors phoned in sick all the time near the end of each month as it cost them less to not go to work and to top it all off the 'free' IR at the end was done in very minimal hours (I think 7-8 hours was the expected norm).
So yes the lure of a job with KLMuk looked very attractive to my mate in the beginning but two years at the hands of what is, sadly very typical, poor management ruins that illusion.
It does sound very grim from that, but I do know that many people have stuck it out and are now flying with the airline, BUT you must be aware of just how bad things are in the period of time before that happens, rich parents and an understanding bank manager can be helpful but then this is what companies like Cabair rely on so you dont feel that they are not supporting you like a responsible employer should and they can get their pound of flesh out of you whilst other people support you through it!
