Unfortunately, to a much larger extent than people probably think or realise, one of the major causes for this, I think, is pilots themselves.
Foxtel is correct. If an employer does not pay you the correct wages, you either "like it or lump it". There is always plenty more drivers lining up behind waiting for that elusive job.
The industry is such that many people will do almost anything, even pay to fly someone else's aicraft, just to get some time up.
The operators that do pay the award are few and far between, with a line of pilots waiting out the door to fill someone's shoes.
If you're holding your breath waiting for a good paying GA job, you better exhale, or you will no doubt pass out!
