Dr Faust,
Very well put indeed.
The reality is this:
Wizz Air will not increase wages substantially for at least these reasons:
1) Not enough people actually leave when compared to the applicants in the system for jobs, and;
2) The wages are, in fact, market leading for those markets Wizz Air employ people in.
I've said it a hundred times before: Wizz offers opportunities for new pilots, co-pilots getting command, new commanders getting other jobs, experienced commanders getting into management or training..... the list goes on.
Once you've had enough of these, then leave. Or stay. The choice is yours.
