I agree, things should be safe for any industry, it's not so.
Just take something like health care, Doctors working 90 hours a week in hospitals, half the number of nurses needed, plus nurses help with the hospitals profits by having to pay for parking at work!
Don't expect help from CASA, if any pilot does come forward they will be the ones worse off, not the company they work for. I have come across people in CASA that were helpful, they are the exception. Nobody wants anything to do with CASA, they are poison.
With most work being casual, expect the pressure to operate with illegal practices to get worse. That's what happens when employees lose any bargaining they had, no choice but do what your told (illegal or not) or no job.
