I cannot understand why anyone with even the merest shred of self-respect would fly on that airline, whether as a flight crew, cabin crew or passenger.
Very simple answer:
Some do not have much choice.
If your dream has been for ages to become a commercial pilot, your flight school tells you not everything about chances getting you a job, and spent 150-200K on the study, you have to make some money to pay the bank the interest and pay back the loan.
Any crew member wants to live, pay rent or mortgage etc etc etc . And need food.
Then there are not many jobs available for pilots. If you are very lucky KLM, BA or any legacy airline offers you a job.
Otherwise you might end up starting you own LTD based in Ireland and will fly on contract and being paid by the flown hours.
And your dept will increase because your typerating needs to be paid back as well. Double trapped into the claws of the airline.
I can image the fear of crews not to whistle blow to the press or co-workers.
Airlines are in charge at the moment. Some with less ethics with and a strong wish for the highest possible profit for the stakeholder abuse the current situation.
