Rights and things
I am not CC but an interested part time pax.
I read a lot here about rights and potential unfairness.
Undoubtably, you will have T&C that were agreed to at some point in time. However, things change. The actual governing principle here is supply and demand.
There are more A/C, more Pilots and many more CC than anyone needs. So the price for each will fall. The unions may be doing a great job in trying to protect working conditions, however, when it comes to money - it will either work for the company or not. If not, no company!
